+/**
+ * Client Interceptors
+ *
+ * This module describes the interceptor framework for clients.
+ * An interceptor is a function which takes an options object and a nextCall
+ * function and returns an InterceptingCall:
+ *
+ * ```
+ * var interceptor = function(options, nextCall) {
+ *   return new InterceptingCall(nextCall(options));
+ * }
+ * ```
+ *
+ * The interceptor function must return an InterceptingCall object. Returning
+ * `new InterceptingCall(nextCall(options))` will satisfy the contract (but
+ * provide no interceptor functionality). `nextCall` is a function which will
+ * generate the next interceptor in the chain.
+ *
+ * To implement interceptor functionality, create a requester and pass it to
+ * the InterceptingCall constructor:
+ *
+ * `return new InterceptingCall(nextCall(options), requester);`
+ *
+ * A requester is a POJO with zero or more of the following methods:
+ *
+ * `start(metadata, listener, next)`
+ * * To continue, call next(metadata, listener). Listeners are described
+ * * below.
+ *
+ * `sendMessage(message, next)`
+ * * To continue, call next(message).
+ *
+ * `halfClose(next)`
+ * * To continue, call next().
+ *
+ * `cancel(message, next)`
+ * * To continue, call next().
+ *
+ * A listener is a POJO with one or more of the following methods:
+ *
+ * `onReceiveMetadata(metadata, next)`
+ * * To continue, call next(metadata)
+ *
+ * `onReceiveMessage(message, next)`
+ * * To continue, call next(message)
+ *
+ * `onReceiveStatus(status, next)`
+ * * To continue, call next(status)
+ *
+ * A listener is provided by the requester's `start` method. The provided
+ * listener implements all the inbound interceptor methods, which can be called
+ * to short-circuit the gRPC call.
+ *
+ * Three usage patterns are supported for listeners:
+ * 1) Pass the listener along without modification: `next(metadata, listener)`.
+ *   In this case the interceptor declines to intercept any inbound operations.
+ * 2) Create a new listener with one or more inbound interceptor methods and
+ *   pass it to `next`. In this case the interceptor will fire on the inbound
+ *   operations implemented in the new listener.
+ * 3) Make direct inbound calls to the provided listener's methods. This
+ *   short-circuits the interceptor stack.
+ *
+ * Do not modify the listener passed in. Either pass it along unmodified,
+ * ignore it, or call methods on it to short-circuit the call.
+ *
+ * To intercept errors, implement the `onReceiveStatus` method and test for
+ * `status.code !== grpc.status.OK`.
+ *
+ * To intercept trailers, examine `status.metadata` in the `onReceiveStatus`
+ * method.
+ *
+ * This is a trivial implementation of all interceptor methods:
+ * var interceptor = function(options, nextCall) {
+ *   return new InterceptingCall(nextCall(options), {
+ *     start: function(metadata, listener, next) {
+ *       next(metadata, {
+ *         onReceiveMetadata: function (metadata, next) {
+ *           next(metadata);
+ *         },
+ *         onReceiveMessage: function (message, next) {
+ *           next(message);
+ *         },
+ *         onReceiveStatus: function (status, next) {
+ *           next(status);
+ *         },
+ *       });
+ *     },
+ *     sendMessage: function(message, next) {
+ *       next(message);
+ *     },
+ *     halfClose: function(next) {
+ *       next();
+ *     },
+ *     cancel: function(message, next) {
+ *       next();
+ *     }
+ *   });
+ * };
+ *
+ * This is an interceptor with a single method:
+ * var interceptor = function(options, nextCall) {
+ *   return new InterceptingCall(nextCall(options), {
+ *     sendMessage: function(message, next) {
+ *       next(message);
+ *     }
+ *   });
+ * };
+ *
+ * Builders are provided for convenience: StatusBuilder, ListenerBuilder,
+ * and RequesterBuilder
+ *
+ * gRPC client operations use this mapping to interceptor methods:
+ *
+ * grpc.opType.SEND_INITIAL_METADATA -> start
+ * grpc.opType.SEND_MESSAGE -> sendMessage
+ * grpc.opType.SEND_CLOSE_FROM_CLIENT -> halfClose
+ * grpc.opType.RECV_INITIAL_METADATA -> onReceiveMetadata

Subject: [PATCH 0125/1899] stronger checking for functions in client.js
 checking for functions simply by instanceof would render library usesless in
 vm or REPL contexts. because if client is created in another V8 context,
 typeof would still return "function" but instanceof Function would fail and
 return false for functions and arrow functions. thus it would be impossible
 to create client before starting a REPL context.

+# Pure JavaScript gRPC Client
+
+## Installation
+
+Node 9.x or greater is required.
+
+```sh
+npm install @grpc/grpc-js
+```
+
+## Features
+
+ - Unary and streaming calls
+ - Cancellation
+ - Deadlines
+ - TLS channel credentials
+ - Call credentials (for auth)
+ - Simple reconnection
+
+This library does not directly handle `.proto` files. To use `.proto` files with this library we recommend using the `@grpc/proto-loader` package.

Subject: [PATCH 0178/1899] fix: avoid using deprecated Nan APIs

deprecated. Instead there are mechanisms in place that allow native
modules to preserve async context across async calls.

 # gRPC Protobuf Loader
 
+A utility package for loading `.proto` files for use with gRPC, using the latest Protobuf.js package.
+
 ## Installation
 
 ```sh
@@ -13,7 +15,37 @@ const protoLoader = require('@grpc/proto-loader');
 const grpcLibrary = require('grpc');
 // OR
 const grpcLibrary = require('@grpc/grpc-js');
-protoLoader.load(protoFile, options).then(packageDefinition => {
+
+protoLoader.load(protoFileName, options).then(packageDefinition => {
   const package = grpcLibrary.loadPackageDefinition(packageDefinition);
 });
+// OR
+const packageDefinition = protoLoader.loadSync(protoFileName, options);
+const package = grpcLibrary.loadPackageDefinition(packageDefinition);
+```
+
+The options parameter is an object that can have the following optional properties:
+
+| Field name | Valid values | Description
+|------------|--------------|------------
+| `keepCase` | `true` or `false` | Preserve field names. The default is to change them to camel case.
+| `longs` | `String` or `Number` | The type to use to represent `long` values. Defaults to a `Long` object type.
+| `enums` | `String` | The type to use to represent `enum` values. Defaults to the numeric value.
+| `bytes` | `Array` or `String` | The type to use to represent `bytes` values. Defaults to `Buffer`.
+| `defaults` | `true` or `false` | Set default values on output objects. Defaults to `false`.
+| `arrays` | `true` or `false` | Set empty arrays for missing array values even if `defaults` is `false` Defaults to `false`.
+| `objects` | `true` or `false` | Set empty objects for missing object values even if `defaults` is `false` Defaults to `false`.
+| `oneofs` | `true` or `false` | Set virtual oneof properties to the present field's name. Defaults to `false`.
+| `include` | An array of strings | A list of search paths for imported `.proto` files.
+
+The following options object closely approximates the existing behavior of `grpc.load`:
+
+```js
+const options = {
+  keepCase: true,
+  longs: String,
+  enums: String,
+  defaults: true,
+  oneofs: true
+}

+## ABOUT ELECTRON
+
+The official electron documentation recommends to [build all of your native packages from source](https://electronjs.org/docs/tutorial/using-native-node-modules#modules-that-rely-on-node-pre-gyp). While the reasons behind this are technically good - many native extensions won't be packaged to work properly with electron - the gRPC source code is fairly difficult to build from source due to its complex nature, and we're also providing working electron pre-built binaries. Therefore, we recommend that you do not follow this model for using gRPC with electron. Also, for the same reason, `electron-rebuild` will always build from source. We advise you to not use this tool if you are depending on gRPC, and use the following instructions instead.
+
+The best to get gRPC to work with electron is to do this, possibly in your postinstall script in your `package.json` file:
+
+```
+npm rebuild --target=2.0.0 --runtime=electron --dist-url=https://atom.io/download/electron
+```
+
+Note that the `2.0.0` above is the electron runtime version number. You will need to update this every time you go on a different version of the runtime.
+
+If you have more native dependencies than gRPC, and they work better when built from source, you can explicitely specify which extension to build the following way:
+
+```
+npm rebuild --build-from-source=sqlite3 --target=2.0.0 --runtime=electron --dist-url=https://atom.io/download/electron
+```
+
+This way, if you depend on both `grpc` and `sqlite3`, only the `sqlite3` package will be rebuilt from source, leaving the `grpc` package to use its precompiled binaries.
+
 ## BUILD FROM SOURCE
  1. Clone [the grpc Git Repository](https://github.com/grpc/grpc).
  2. Run `npm install --build-from-source` from the repository root.

Subject: [PATCH 0312/1899] Replaces `string` type with actual possible values

Enhances documentation of the `type` argument for `grpc.Server.register`, leveraging on JSDoc's support for literal enumerations.

This keeps developers from having to dig through the source code to find the valid values.

 This library does not directly handle `.proto` files. To use `.proto` files with this library we recommend using the `@grpc/proto-loader` package.
+
+## Some Notes on API Guarantees
+
+The public API of this library follows semantic versioning, with some caveats:
+
+ - Some methods are prefixed with an underscore. These methods are internal and should not be considered part of the public API.
+ - The class `Call` is only exposed due to limitations of TypeScript. It should not be considered part of the public API.
+ - In general, any API that is exposed by this library but is not exposed by the `grpc` library is likely an error and should not be considered part of the public API.

Subject: [PATCH 0366/1899] grpc-js-core: simplify regular expression usage

This commit moves two regular expressions out of the functions
they are used in, and defines them as constants. This commit
also switches from match() to test(), as a Boolean result is
all that's needed.

+## BUILD FROM SOURCE
+
+The following command can be used to build from source when installing the package from npm:
+
+```
+npm install grpc --build-from-source
+```
+
+The `--build-from-source` option will work even when installing another package that depends on `grpc`. To build only `grpc` from source, you can use the argument `--build-from-source=grpc`.
+
 ## ABOUT ELECTRON
 
 The official electron documentation recommends to [build all of your native packages from source](https://electronjs.org/docs/tutorial/using-native-node-modules#modules-that-rely-on-node-pre-gyp). While the reasons behind this are technically good - many native extensions won't be packaged to work properly with electron - the gRPC source code is fairly difficult to build from source due to its complex nature, and we're also providing working electron pre-built binaries. Therefore, we recommend that you do not follow this model for using gRPC with electron. Also, for the same reason, `electron-rebuild` will always build from source. We advise you to not use this tool if you are depending on gRPC. Please note that there's not just one way to get native extensions running in electron, and that there's never any silver bullet for anything. The following instructions try to cater about some of the most generic ways, but different edge cases might require different methodologies.

 This way, if you depend on both `grpc` and `sqlite3`, only the `sqlite3` package will be rebuilt from source, leaving the `grpc` package to use its precompiled binaries.
 
-## BUILD FROM SOURCE
- 1. Clone [the grpc Git Repository](https://github.com/grpc/grpc).
- 2. Run `npm install --build-from-source` from the repository root.

+ 4. Run `npm install --build-from-source`.
 
  - **Note:** On Windows, this might fail due to [nodejs issue #4932](https://github.com/nodejs/node/issues/4932) in which case, you will see something like the following in `npm install`'s output (towards the very beginning):

Subject: [PATCH 0398/1899] grpc-js-core: delay composing credentials

The channel and stream credentials may change between the time
a CallCredentialsFilterFactory is created and the time that
the metadata is sent. This commit delays composing the credentials
until the time metadata is sent.

Subject: [PATCH 0422/1899] grpc-js-core: use Map for metadata store

In more recent versions of Node, Maps are more performant than
POJOs when used as maps. Switching to Maps also eliminates an
expensive delete operation, as well as uses of hasOwnProperty().

Subject: [PATCH 0424/1899] grpc-js-core: simplify Metadata clone()

This commit inlines the only use of cloneMetadataObject(). It
also eliminates an extra MetadataObject - the result of
cloneMetadataObject() was allocating a new MetadataObject to
replace the internal representation of the newly allocated
Metadata object in clone().

Subject: [PATCH 0430/1899] grpc-js-core: remove use of flow() and flowRight()

This commit replaces combinations of bind(), map(), and
flow() with simple for loops. This improves performance, and
lessens the dependency on lodash.

Subject: [PATCH 0432/1899] grpc-js-core: remove simple uses of lodash

This commit removes lodash as a production dependency. It
remains as a devDependency because it's used in tests, but the
uses in the src/ directory were easily replaced with vanilla
JavaScript.

Subject: [PATCH 0545/1899] Fix grpc-tools install script

This allows npm to determine the path to `node-pre-gyp` for the install
script from `grpc-tools` rather than specifying the path. This also
brings the install script in line with the one used for the `grpc`
package.

+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+

+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,

+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

Subject: [PATCH 0638/1899] Native: Remove unused ChannelCredential type
 definitions

Removes:
- getCallCredentials
- getSecureContext

These functions no longer exist, so their presence in the type
definitions is invalid.

Subject: [PATCH 0662/1899] Fix a TypeError loading a non-existent proto file.

The issue: https://github.com/grpc/grpc-node/issues/876

This is an obvious typo; `typeof` has to return a string `'undefined'`, not a literal `undefined.`

Subject: [PATCH 0674/1899] grpc-js: reject invalid Content-Type requests

This commit implements the following portion of the spec:

If Content-Type does not begin with "application/grpc",
gRPC servers SHOULD respond with HTTP status of
415 (Unsupported Media Type). This will prevent other
HTTP/2 clients from interpreting a gRPC error response,
which uses status 200 (OK), as successful.

Subject: [PATCH 0686/1899] grpc-js: handle multiple messages in single 'data'
 event

This commit adds support for receiving multiple messages in a
single 'data' event from the underlying HTTP2 stream. It also
handles potential out of order messages due to asynchronous
deserialization of messages.

Subject: [PATCH 0709/1899] grpc-js: shutdown improvements

This commit maintains a Set of all active sessions. This allows
tryShutdown() to gracefully stop the server properly (as
recommended in the Node HTTP2 documentation). The same Set of
sessions also allows forceShutdown() to be implemented.

Subject: [PATCH 0711/1899] test: make connctivity test more robust

The key change here is forcing the final unary call to
wait for the server to be ready. The native client was
making the RPC, but didn't appear to have a valid
connection at the time.

 The official electron documentation recommends to [build all of your native packages from source](https://electronjs.org/docs/tutorial/using-native-node-modules#modules-that-rely-on-node-pre-gyp). While the reasons behind this are technically good - many native extensions won't be packaged to work properly with electron - the gRPC source code is fairly difficult to build from source due to its complex nature, and we're also providing working electron pre-built binaries. Therefore, we recommend that you do not follow this model for using gRPC with electron. Also, for the same reason, `electron-rebuild` will always build from source. We advise you to not use this tool if you are depending on gRPC. Please note that there's not just one way to get native extensions running in electron, and that there's never any silver bullet for anything. The following instructions try to cater about some of the most generic ways, but different edge cases might require different methodologies.

Subject: [PATCH 0719/1899] Fix 'noImplicitAny' issue with declaration file.

The latest release of grpc-node cannot be used in a typescript project that uses -noImplicitAny.  This is due to a signature being added without a specified return type.  This causes the return type to implicitly be 'any' which TS explicitly disallows.  For projects that use strict flags to catch lots of bugs, this prevents usage of this version of grpc entirely.

+# grpc-health-check
+
+Health check client and service for use with gRPC-node.
+
+## Background
+
+This package exports both a client and server that adhere to the [gRPC Health Checking Protocol](https://github.com/grpc/grpc/blob/master/doc/health-checking.md).
+
+By using this package, clients and servers can rely on common proto and service definitions. This means:
+- Clients can use the generated stubs to health check _any_ server that adheres to the protocol.
+- Servers do not reimplement common logic for publishing health statuses.
+
+## Installation
+
+Use the package manager [npm](https://www.npmjs.com/get-npm) to install `grpc-health-check`.
+
+```bash
+npm install grpc-health-check
+```
+
+## Usage
+
+### Server
+
+Any gRPC-node server can use `grpc-health-check` to adhere to the gRPC Health Checking Protocol. 
+The following shows how this package can be added to a pre-existing gRPC server.
+
+```javascript 1.8
+// Import package
+let health = require('grpc-health-check');
+
+// Define service status map. Key is the service name, value is the corresponding status.
+// By convention, the empty string "" key represents that status of the entire server.
+const statusMap = {
+  "ServiceFoo": proto.grpc.health.v1.HealthCheckResponse.ServingStatus.SERVING,
+  "ServiceBar": proto.grpc.health.v1.HealthCheckResponse.ServingStatus.NOT_SERVING,
+  "": proto.grpc.health.v1.HealthCheckResponse.ServingStatus.NOT_SERVING,
+};
+
+// Construct the service implementation
+let healthImpl = new health.Implementation(statusMap);
+
+// Add the service and implementation to your pre-existing gRPC-node server
+server.addService(health.service, healthImpl);
+```
+
+Congrats! Your server now allows any client to run a health check against it.
+
+### Client
+
+Any gRPC-node client can use `grpc-health-check` to run health checks against other servers that follow the protocol.
+The following shows how this package can be used by a pre-existing gRPC client.
+
+```javascript 1.8
+// Import package
+let grpc = require('grpc');
+let health = require('grpc-health-check');
+
+// Create the client
+let healthClient = new health.Client('localhost:8082', grpc.credentials.createInsecure());
+
+// Define the request, which contains the service to health check
+// By convention, the empty string "" key represents that status of the entire server.
+let request = {
+  service: "",
+};
+
+// Define the callback
+function callback (error, status) {
+  if (error) {
+    console.error(error);
+    return;
+  }
+
+  console.log(status);
+}
+
+// Make the request
+healthClient.check(request, callback);
+```
+
+This should print out "NOT_SERVING" if used with the server above.

 ### Client
 
 Any gRPC-node client can use `grpc-health-check` to run health checks against other servers that follow the protocol.
-The following shows how this package can be used by a pre-existing gRPC client.
-
-```javascript 1.8
-// Import package
-let grpc = require('grpc');
-let health = require('grpc-health-check');
-
-// Create the client
-let healthClient = new health.Client('localhost:8082', grpc.credentials.createInsecure());
-
-// Define the request, which contains the service to health check
-// By convention, the empty string "" key represents that status of the entire server.
-let request = {
-  service: "",
-};
-
-// Define the callback
-function callback (error, status) {
-  if (error) {
-    console.error(error);
-    return;
-  }
-
-  console.log(status);
-}
-
-// Make the request
-healthClient.check(request, callback);
-```
-
-This should print out "NOT_SERVING" if used with the server above.

+# Compression
+
+## Client side
+The preferred method for configuring message compression on a client is to pass `options` when the client object is instantiated.
+
+The two options need to be passed:
+
+**grpc.default_compression_algorithm** (integer)
+
+The option keeps the value of a compression algorithm.
+
+Possible values for this option are:
+- `0` - No compression
+- `1` - Compress with DEFLATE algorithm
+- `2` - Compress with GZIP algorithm
+- `3` - Stream compression with GZIP algorithm
+
+**grpc.default_compression_level** (integer)
+
+The option keeps the value for the level of compression.
+
+Possible values for this option are:
+- `0` - None
+- `1` - Low level
+- `2` - Medium level
+- `3` - High level
+
+### Code example
+```javascript
+client = new ExampleClient("example.com", credentials.createInsecure(), {'grpc.default_compression_algorithm': 2, 'grpc.default_compression_level': 2});
+```

-**This library is currently incomplete and experimental. It is built on the [http2 Node module](https://nodejs.org/api/http2.html).**
-
 This library implements the core functionality of gRPC purely in JavaScript, without a C++ addon. It works on the latest version of Node.js on all platforms that Node.js runs on.

Subject: [PATCH 1018/1899] grpc-js: Remove watcher from queue before calling
 watcher callback. Fixes #1352

In the case where a new watcher is synchronously added to the watcher queue via the
watcher callback, this can result in the callback being called multiple times.

To support this case, the watcher needs to be move removed from the queue
before calling the watcher callback.

 This library does not directly handle `.proto` files. To use `.proto` files with this library we recommend using the `@grpc/proto-loader` package.
 
+ ## Migrating from [`grpc`](https://www.npmjs.com/package/grpc)
+
+ `@grpc/grpc-js` is almost a drop-in replacement for `grpc`, but you may need to make a few code changes to use it:
+
+ - If you are currently loading `.proto` files using `grpc.load`, that function is not available in this library. You should instead load your `.proto` files using `@grpc/proto-loader` and load the resulting package definition objects into `@grpc/grpc-js` using `grpc.loadPackageDefinition`.
+ - If you are currently loading packages generated by `grpc-tools`, you should instead generate your files using the `--generate_package_definitions` option in `grpc-tools`, then load the object exported by the generated file into `@grpc/grpc-js` using `grpc.loadPackageDefinition`.
+ - If you have a server and you are using `Server#bind` to bind ports, you will need to use `Server#bindAsync` instead.
+
 ## Some Notes on API Guarantees
 
 The public API of this library follows semantic versioning, with some caveats:

 ## Some Notes on API Guarantees
 
 The public API of this library follows semantic versioning, with some caveats:
 
- - Some methods are prefixed with an underscore. These methods are internal and should not be considered part of the public API.
- - The class `Call` is only exposed due to limitations of TypeScript. It should not be considered part of the public API.
- - In general, any API that is exposed by this library but is not exposed by the `grpc` library is likely an error and should not be considered part of the public API.

+# grpc-tools
+
+This package distributes the Protocol Buffers compiler `protoc` along with the
+plugin for generating client and service objects for use with the Node gRPC
+libraries.
+
+## Usage
+
+This library exports the `grpc_tools_node_protoc` executable, which accepts all
+of the same arguments as `protoc` itself. For use with Node, you most likely
+want to use CommonJS-style imports. An example of generating code this way can
+be found in [this guide](https://developers.google.com/protocol-buffers/docs/reference/javascript-generated#commonjs-imports).
+The `grpc_tools_node_protoc` automatically includes the Node gRPC plugin, so
+it also accepts the `--grpc_out=[option:]path` argument. The option can be
+one of the following:
+
+ - `grpc_js`: Generates code with `require('@grpc/grpc-js')` instead of
+   `require('grpc')`
+ - `generate_package_definition`: Generates code that does not `require` any
+   gRPC library, and instead generates `PackageDefinition` objects that can
+   be passed to the `loadPackageDefinition` function provided by both the
+   `grpc` and `@grpc/grpc-js` libraries.

-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,

-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-# Node.js gRPC Library
-
-## PREREQUISITES
-- `node`: This requires `node` to be installed, version `4.0` or above. If you instead have the `nodejs` executable on Debian, you should install the [`nodejs-legacy`](https://packages.debian.org/sid/nodejs-legacy) package.
-
-- **Note:** If you installed `node` via a package manager and the version is still less than `4.0`, try directly installing it from [nodejs.org](https://nodejs.org).
-
-## INSTALLATION
-
-Install the gRPC NPM package
-
-```sh
-npm install grpc
-```
-
-## BUILD FROM SOURCE
-
-The following command can be used to build from source when installing the package from npm:
-
-```
-npm install grpc --build-from-source
-```
-
-The `--build-from-source` option will work even when installing another package that depends on `grpc`. To build only `grpc` from source, you can use the argument `--build-from-source=grpc`.
-
-## ABOUT ELECTRON
-
-The official electron documentation recommends to [build all of your native packages from source](https://electronjs.org/docs/tutorial/using-native-node-modules#modules-that-rely-on-node-pre-gyp). While the reasons behind this are technically good - many native extensions won't be packaged to work properly with electron - the gRPC source code is fairly difficult to build from source due to its complex nature, and we're also providing working electron pre-built binaries. Therefore, we recommend that you do not follow this model for using gRPC with electron. Also, for the same reason, `electron-rebuild` will always build from source. We advise you to not use this tool if you are depending on gRPC. Please note that there's not just one way to get native extensions running in electron, and that there's never any silver bullet for anything. The following instructions try to cater about some of the most generic ways, but different edge cases might require different methodologies.
-
-The best way to get gRPC to work with electron is to do this, possibly in the `postinstall` script of your `package.json` file:
-
-```
-npm rebuild --target=2.0.0 --runtime=electron --dist-url=https://atom.io/download/electron
-```
-
-Note that the `2.0.0` above is the electron runtime version number. You will need to update this every time you go on a different version of the runtime.
-
-If you have more native dependencies than gRPC, and they work better when built from source, you can explicitely specify which extension to build the following way:
-
-```
-npm rebuild --build-from-source=sqlite3 --target=2.0.0 --runtime=electron --dist-url=https://atom.io/download/electron
-```
-
-This way, if you depend on both `grpc` and `sqlite3`, only the `sqlite3` package will be rebuilt from source, leaving the `grpc` package to use its precompiled binaries.
-
-## BUILD IN GIT REPOSITORY
-
- 1. Clone [the grpc-node Git Repository](https://github.com/grpc/grpc-node).
- 2. Run `git submodule update --init --recursive` from the repository root.
- 3. Run `cd packages/grpc-native-core`.
- 4. Run `npm install --build-from-source`.
-
- - **Note:** On Windows, this might fail due to [nodejs issue #4932](https://github.com/nodejs/node/issues/4932) in which case, you will see something like the following in `npm install`'s output (towards the very beginning):
-
-    ```
-     ..
-     Building the projects in this solution one at a time. To enable parallel build, please add the "/m" switch.
-     WINDOWS_BUILD_WARNING
-      "..\IMPORTANT: Due to https:\github.com\nodejs\node\issues\4932, to build this library on Windows, you must first remove C:\Users\jenkins\.node-gyp\4.4.0\include\node\openssl"
-      ...
-      ..
-    ```
-
-    To fix this, you will have to delete the folder `C:\Users\<username>\.node-gyp\<node_version>\include\node\openssl` and retry `npm install`
-
-## CONFIGURE BINARIES' LOCATION
-
-You can configure the location from which the pre-compiled binaries are downloaded during installation.
-
-`npm install --grpc_node_binary_host_mirror=https://your-url.com`
-
-Or defining `grpc_node_binary_host_mirror` in your `.npmrc`.
-
-## API DOCUMENTATION
-
-See the [API Documentation](https://grpc.io/grpc/node/).
-
-## TESTING
-To run the test suite, simply run `npm test` in the install location.
+The `grpc` npm pacakge previously lived in this package. It has been removed. It now lives in the [`grpc@1.24.x` branch](https://github.com/grpc/grpc-node/tree/grpc%401.24.x/packages/grpc-native-core) where bugfixes are still being applied.

-/**
- * Client Interceptors
- *
- * This module describes the interceptor framework for clients.
- * An interceptor is a function which takes an options object and a nextCall
- * function and returns an InterceptingCall:
- *
- * ```
- * var interceptor = function(options, nextCall) {
- *   return new InterceptingCall(nextCall(options));
- * }
- * ```
- *
- * The interceptor function must return an InterceptingCall object. Returning
- * `new InterceptingCall(nextCall(options))` will satisfy the contract (but
- * provide no interceptor functionality). `nextCall` is a function which will
- * generate the next interceptor in the chain.
- *
- * To implement interceptor functionality, create a requester and pass it to
- * the InterceptingCall constructor:
- *
- * `return new InterceptingCall(nextCall(options), requester);`
- *
- * A requester is a POJO with zero or more of the following methods:
- *
- * `start(metadata, listener, next)`
- * * To continue, call next(metadata, listener). Listeners are described
- * * below.
- *
- * `sendMessage(message, next)`
- * * To continue, call next(message).
- *
- * `halfClose(next)`
- * * To continue, call next().
- *
- * `cancel(next)`
- * * To continue, call next().
- *
- * A listener is a POJO with one or more of the following methods:
- *
- * `onReceiveMetadata(metadata, next)`
- * * To continue, call next(metadata)
- *
- * `onReceiveMessage(message, next)`
- * * To continue, call next(message)
- *
- * `onReceiveStatus(status, next)`
- * * To continue, call next(status)
- *
- * A listener is provided by the requester's `start` method. The provided
- * listener implements all the inbound interceptor methods, which can be called
- * to short-circuit the gRPC call.
- *
- * Three usage patterns are supported for listeners:
- * 1) Pass the listener along without modification: `next(metadata, listener)`.
- *   In this case the interceptor declines to intercept any inbound operations.
- * 2) Create a new listener with one or more inbound interceptor methods and
- *   pass it to `next`. In this case the interceptor will fire on the inbound
- *   operations implemented in the new listener.
- * 3) Make direct inbound calls to the provided listener's methods. This
- *   short-circuits the interceptor stack.
- *
- * Do not modify the listener passed in. Either pass it along unmodified,
- * ignore it, or call methods on it to short-circuit the call.
- *
- * To intercept errors, implement the `onReceiveStatus` method and test for
- * `status.code !== grpc.status.OK`.
- *
- * To intercept trailers, examine `status.metadata` in the `onReceiveStatus`
- * method.
- *
- * This is a trivial implementation of all interceptor methods:
- * var interceptor = function(options, nextCall) {
- *   return new InterceptingCall(nextCall(options), {
- *     start: function(metadata, listener, next) {
- *       next(metadata, {
- *         onReceiveMetadata: function (metadata, next) {
- *           next(metadata);
- *         },
- *         onReceiveMessage: function (message, next) {
- *           next(message);
- *         },
- *         onReceiveStatus: function (status, next) {
- *           next(status);
- *         },
- *       });
- *     },
- *     sendMessage: function(message, next) {
- *       next(message);
- *     },
- *     halfClose: function(next) {
- *       next();
- *     },
- *     cancel: function(next) {
- *       next();
- *     }
- *   });
- * };
- *
- * This is an interceptor with a single method:
- * var interceptor = function(options, nextCall) {
- *   return new InterceptingCall(nextCall(options), {
- *     sendMessage: function(message, next) {
- *       next(message);
- *     }
- *   });
- * };
- *
- * Builders are provided for convenience: StatusBuilder, ListenerBuilder,
- * and RequesterBuilder
- *
- * gRPC client operations use this mapping to interceptor methods:
- *
- * grpc.opType.SEND_INITIAL_METADATA -> start
- * grpc.opType.SEND_MESSAGE -> sendMessage
- * grpc.opType.SEND_CLOSE_FROM_CLIENT -> halfClose
- * grpc.opType.RECV_INITIAL_METADATA -> onReceiveMetadata
- * grpc.opType.RECV_MESSAGE -> onReceiveMessage
- * grpc.opType.RECV_STATUS_ON_CLIENT -> onReceiveStatus
- *

Subject: [PATCH 1118/1899] Update node-pre-gyp to pickup fix for #1362

node-pre-gyp 0.12.0 uses needle 2.4.1 which has the bug in it.
Even with grpc 1.24.3, which refers to the updated version, it seems npm can decide to use the older version referenced by this package.

+       * 
+       * Each mapping specifies a URL path template and an HTTP method. The path

+       * as each field is a non-repeated field with a primitive (non-message) type.
+       * The path template controls how fields of the request message are mapped to
+       * the URL path.
+       * 
+       * Example:
+       * 
+       * service Messaging {
+       * rpc GetMessage(GetMessageRequest) returns (Message) {

+       * 
+       * Any fields in the request message which are not bound by the path template
+       * automatically become HTTP query parameters if there is no HTTP request body.
+       * For example:
+       * 
+       * service Messaging {
+       * rpc GetMessage(GetMessageRequest) returns (Message) {

+       * int64 revision = 2;    // Mapped to URL query parameter `revision`.
+       * SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
+       * }
+       * 
+       * This enables a HTTP JSON to RPC mapping as below:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `GET /v1/messages/123456?revision=2&sub.subfield=foo` |
+       * `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield:
+       * "foo"))`
+       * 
+       * Note that fields which are mapped to URL query parameters must have a
+       * primitive type or a repeated primitive type or a non-repeated message type.
+       * In the case of a repeated type, the parameter can be repeated in the URL
+       * as `...?param=A&param=B`. In the case of a message type, each field of the
+       * message is mapped to a separate parameter, such as
+       * `...?foo.a=A&foo.b=B&foo.c=C`.
+       * 
+       * For HTTP methods that allow a request body, the `body` field
+       * specifies the mapping. Consider a REST update method on the
+       * message resource collection:
+       * 
+       * service Messaging {
+       * rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
+       * option (google.api.http) = {

+       * body: "message"
+       * };
+       * }
+       * }
+       * message UpdateMessageRequest {
+       * string message_id = 1; // mapped to the URL
+       * Message message = 2;   // mapped to the body
+       * }
+       * 
+       * The following HTTP JSON to RPC mapping is enabled, where the
+       * representation of the JSON in the request body is determined by
+       * protos JSON encoding:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+       * "123456" message { text: "Hi!" })`
+       * 
+       * The special name `*` can be used in the body mapping to define that
+       * every field not bound by the path template should be mapped to the
+       * request body.  This enables the following alternative definition of
+       * the update method:
+       * 
+       * service Messaging {
+       * rpc UpdateMessage(Message) returns (Message) {
+       * option (google.api.http) = {
+       * patch: "/v1/messages/{message_id}"
+       * body: "*"
+       * };
+       * }
+       * }
+       * message Message {
+       * string message_id = 1;
+       * string text = 2;
+       * }
+       * 
+       * 
+       * The following HTTP JSON to RPC mapping is enabled:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+       * "123456" text: "Hi!")`
+       * 
+       * Note that when using `*` in the body mapping, it is not possible to
+       * have HTTP parameters, as all fields not bound by the path end in
+       * the body. This makes this option more rarely used in practice when
+       * defining REST APIs. The common usage of `*` is in custom methods
+       * which don't use the URL at all for transferring data.
+       * 
+       * It is possible to define multiple HTTP methods for one RPC by using
+       * the `additional_bindings` option. Example:
+       * 
+       * service Messaging {
+       * rpc GetMessage(GetMessageRequest) returns (Message) {
+       * option (google.api.http) = {
+       * get: "/v1/messages/{message_id}"
+       * additional_bindings {
+       * get: "/v1/users/{user_id}/messages/{message_id}"
+       * }
+       * };
+       * }
+       * }
+       * message GetMessageRequest {
+       * string message_id = 1;
+       * string user_id = 2;
+       * }
+       * 
+       * This enables the following two alternative HTTP JSON to RPC mappings:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
+       * `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id:
+       * "123456")`
+       * 
+       * ## Rules for HTTP mapping
+       * 
+       * 1. Leaf request fields (recursive expansion nested messages in the request
+       * message) are classified into three categories:
+       * - Fields referred by the path template. They are passed via the URL path.
+       * - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They are passed via the HTTP
+       * request body.
+       * - All other fields are passed via the URL query parameters, and the
+       * parameter name is the field path in the request message. A repeated
+       * field can be represented as multiple query parameters under the same
+       * name.
+       * 2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields
+       * are passed via URL path and HTTP request body.
+       * 3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP request body, all
+       * fields are passed via URL path and URL query parameters.
+       * 
+       * ### Path template syntax
+       * 
+       * Template = "/" Segments [ Verb ] ;
+       * Segments = Segment { "/" Segment } ;
+       * Segment  = "*" | "**" | LITERAL | Variable ;
+       * Variable = "{" FieldPath [ "=" Segments ] "}" ;
+       * FieldPath = IDENT { "." IDENT } ;
+       * Verb     = ":" LITERAL ;
+       * 
+       * The syntax `*` matches a single URL path segment. The syntax `**` matches
+       * zero or more URL path segments, which must be the last part of the URL path
+       * except the `Verb`.
+       * 
+       * The syntax `Variable` matches part of the URL path as specified by its
+       * template. A variable template must not contain other variables. If a variable
+       * matches a single path segment, its template may be omitted, e.g. `{var}`
+       * is equivalent to `{var=*}`.
+       * 
+       * The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
+       * contains any reserved character, such characters should be percent-encoded
+       * before the matching.
+       * 
+       * If a variable contains exactly one path segment, such as `"{var}"` or
+       * `"{var=*}"`, when such a variable is expanded into a URL path on the client
+       * side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The
+       * server side does the reverse decoding. Such variables show up in the
+       * [Discovery
+       * Document](https://developers.google.com/discovery/v1/reference/apis) as
+       * `{var}`.
+       * 
+       * If a variable contains multiple path segments, such as `"{var=foo/*}"`
+       * or `"{var=**}"`, when such a variable is expanded into a URL path on the
+       * client side, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded.
+       * The server side does the reverse decoding, except "%2F" and "%2f" are left
+       * unchanged. Such variables show up in the
+       * [Discovery
+       * Document](https://developers.google.com/discovery/v1/reference/apis) as
+       * `{+var}`.
+       * 
+       * ## Using gRPC API Service Configuration
+       * 
+       * gRPC API Service Configuration (service config) is a configuration language
+       * for configuring a gRPC service to become a user-facing product. The
+       * service config is simply the YAML representation of the `google.api.Service`
+       * proto message.
+       * 
+       * As an alternative to annotating your proto file, you can configure gRPC
+       * transcoding in your service config YAML files. You do this by specifying a
+       * `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same
+       * effect as the proto annotation. This can be particularly useful if you
+       * have a proto that is reused in multiple services. Note that any transcoding
+       * specified in the service config will override any matching transcoding
+       * configuration in the proto.
+       * 
+       * Example:
+       * 
+       * http:
+       * rules:
+       * # Selects a gRPC method and applies HttpRule to it.
+       * - selector: example.v1.Messaging.GetMessage
+       * get: /v1/messages/{message_id}/{sub.subfield}
+       * 
+       * ## Special notes
+       * 
+       * When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
+       * proto to JSON conversion must follow the [proto3
+       * specification](https://developers.google.com/protocol-buffers/docs/proto3#json).
+       * 
+       * While the single segment variable follows the semantics of
+       * [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
+       * Expansion, the multi segment variable **does not** follow RFC 6570 Section
+       * 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
+       * does not expand special characters like `?` and `#`, which would lead
+       * to invalid URLs. As the result, gRPC Transcoding uses a custom encoding
+       * for multi segment variables.
+       * 
+       * The path variables **must not** refer to any repeated or mapped field,
+       * because client libraries are not capable of handling such variable expansion.
+       * 
+       * The path variables **must not** capture the leading "/" character. The reason
+       * is that the most common use case "{var}" does not capture the leading "/"
+       * character. For consistency, all path variables must share the same behavior.
+       * 
+       * Repeated message fields must not be mapped to URL query parameters, because
+       * no client library can support such complicated mapping.
+       * 
+       * If an API needs to use a JSON array for request or response body, it can map
+       * the request or response body to a repeated field. However, some gRPC
+       * Transcoding implementations may not support this feature.

+       * protos JSON encoding:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+       * "123456" message { text: "Hi!" })`
+       * 
+       * The special name `*` can be used in the body mapping to define that
+       * every field not bound by the path template should be mapped to the
+       * request body.  This enables the following alternative definition of
+       * the update method:
+       * 
+       * service Messaging {
+       * rpc UpdateMessage(Message) returns (Message) {
+       * option (google.api.http) = {
+       * patch: "/v1/messages/{message_id}"
+       * body: "*"
+       * };
+       * }
+       * }
+       * message Message {
+       * string message_id = 1;
+       * string text = 2;
+       * }
+       * 
+       * 
+       * The following HTTP JSON to RPC mapping is enabled:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+       * "123456" text: "Hi!")`
+       * 
+       * Note that when using `*` in the body mapping, it is not possible to
+       * have HTTP parameters, as all fields not bound by the path end in
+       * the body. This makes this option more rarely used in practice when
+       * defining REST APIs. The common usage of `*` is in custom methods
+       * which don't use the URL at all for transferring data.
+       * 
+       * It is possible to define multiple HTTP methods for one RPC by using
+       * the `additional_bindings` option. Example:
+       * 
+       * service Messaging {
+       * rpc GetMessage(GetMessageRequest) returns (Message) {
+       * option (google.api.http) = {
+       * get: "/v1/messages/{message_id}"
+       * additional_bindings {
+       * get: "/v1/users/{user_id}/messages/{message_id}"
+       * }
+       * };
+       * }
+       * }
+       * message GetMessageRequest {
+       * string message_id = 1;
+       * string user_id = 2;
+       * }
+       * 
+       * This enables the following two alternative HTTP JSON to RPC mappings:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
+       * `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id:
+       * "123456")`
+       * 
+       * ## Rules for HTTP mapping
+       * 
+       * 1. Leaf request fields (recursive expansion nested messages in the request
+       * message) are classified into three categories:
+       * - Fields referred by the path template. They are passed via the URL path.
+       * - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They are passed via the HTTP
+       * request body.
+       * - All other fields are passed via the URL query parameters, and the
+       * parameter name is the field path in the request message. A repeated
+       * field can be represented as multiple query parameters under the same
+       * name.
+       * 2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields
+       * are passed via URL path and HTTP request body.
+       * 3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP request body, all
+       * fields are passed via URL path and URL query parameters.
+       * 
+       * ### Path template syntax
+       * 
+       * Template = "/" Segments [ Verb ] ;
+       * Segments = Segment { "/" Segment } ;
+       * Segment  = "*" | "**" | LITERAL | Variable ;
+       * Variable = "{" FieldPath [ "=" Segments ] "}" ;
+       * FieldPath = IDENT { "." IDENT } ;
+       * Verb     = ":" LITERAL ;
+       * 
+       * The syntax `*` matches a single URL path segment. The syntax `**` matches
+       * zero or more URL path segments, which must be the last part of the URL path
+       * except the `Verb`.
+       * 
+       * The syntax `Variable` matches part of the URL path as specified by its
+       * template. A variable template must not contain other variables. If a variable
+       * matches a single path segment, its template may be omitted, e.g. `{var}`
+       * is equivalent to `{var=*}`.
+       * 
+       * The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
+       * contains any reserved character, such characters should be percent-encoded
+       * before the matching.
+       * 
+       * If a variable contains exactly one path segment, such as `"{var}"` or
+       * `"{var=*}"`, when such a variable is expanded into a URL path on the client
+       * side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The
+       * server side does the reverse decoding. Such variables show up in the
+       * [Discovery
+       * Document](https://developers.google.com/discovery/v1/reference/apis) as
+       * `{var}`.
+       * 
+       * If a variable contains multiple path segments, such as `"{var=foo/*}"`
+       * or `"{var=**}"`, when such a variable is expanded into a URL path on the
+       * client side, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded.
+       * The server side does the reverse decoding, except "%2F" and "%2f" are left
+       * unchanged. Such variables show up in the
+       * [Discovery
+       * Document](https://developers.google.com/discovery/v1/reference/apis) as
+       * `{+var}`.
+       * 
+       * ## Using gRPC API Service Configuration
+       * 
+       * gRPC API Service Configuration (service config) is a configuration language
+       * for configuring a gRPC service to become a user-facing product. The
+       * service config is simply the YAML representation of the `google.api.Service`
+       * proto message.
+       * 
+       * As an alternative to annotating your proto file, you can configure gRPC
+       * transcoding in your service config YAML files. You do this by specifying a
+       * `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same
+       * effect as the proto annotation. This can be particularly useful if you
+       * have a proto that is reused in multiple services. Note that any transcoding
+       * specified in the service config will override any matching transcoding
+       * configuration in the proto.
+       * 
+       * Example:
+       * 
+       * http:
+       * rules:
+       * # Selects a gRPC method and applies HttpRule to it.
+       * - selector: example.v1.Messaging.GetMessage
+       * get: /v1/messages/{message_id}/{sub.subfield}
+       * 
+       * ## Special notes
+       * 
+       * When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
+       * proto to JSON conversion must follow the [proto3
+       * specification](https://developers.google.com/protocol-buffers/docs/proto3#json).
+       * 
+       * While the single segment variable follows the semantics of
+       * [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
+       * Expansion, the multi segment variable **does not** follow RFC 6570 Section
+       * 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
+       * does not expand special characters like `?` and `#`, which would lead
+       * to invalid URLs. As the result, gRPC Transcoding uses a custom encoding
+       * for multi segment variables.
+       * 
+       * The path variables **must not** refer to any repeated or mapped field,
+       * because client libraries are not capable of handling such variable expansion.
+       * 
+       * The path variables **must not** capture the leading "/" character. The reason
+       * is that the most common use case "{var}" does not capture the leading "/"
+       * character. For consistency, all path variables must share the same behavior.
+       * 
+       * Repeated message fields must not be mapped to URL query parameters, because
+       * no client library can support such complicated mapping.
+       * 
+       * If an API needs to use a JSON array for request or response body, it can map
+       * the request or response body to a repeated field. However, some gRPC
+       * Transcoding implementations may not support this feature.

+       * 
+       * Each mapping specifies a URL path template and an HTTP method. The path
+       * template may refer to one or more fields in the gRPC request message, as long
+       * as each field is a non-repeated field with a primitive (non-message) type.
+       * The path template controls how fields of the request message are mapped to
+       * the URL path.
+       * 
+       * Example:
+       * 
+       * service Messaging {
+       * rpc GetMessage(GetMessageRequest) returns (Message) {

+       * 
+       * Any fields in the request message which are not bound by the path template
+       * automatically become HTTP query parameters if there is no HTTP request body.

+       * int64 revision = 2;    // Mapped to URL query parameter `revision`.
+       * SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
+       * }
+       * 
+       * This enables a HTTP JSON to RPC mapping as below:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `GET /v1/messages/123456?revision=2&sub.subfield=foo` |
+       * `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield:
+       * "foo"))`
+       * 
+       * Note that fields which are mapped to URL query parameters must have a
+       * primitive type or a repeated primitive type or a non-repeated message type.
+       * In the case of a repeated type, the parameter can be repeated in the URL
+       * as `...?param=A&param=B`. In the case of a message type, each field of the
+       * message is mapped to a separate parameter, such as
+       * `...?foo.a=A&foo.b=B&foo.c=C`.
+       * 
+       * For HTTP methods that allow a request body, the `body` field
+       * specifies the mapping. Consider a REST update method on the
+       * message resource collection:
+       * 
+       * service Messaging {
+       * rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
+       * option (google.api.http) = {
+       * patch: "/v1/messages/{message_id}"
+       * body: "message"
+       * };
+       * }
+       * }
+       * message UpdateMessageRequest {
+       * string message_id = 1; // mapped to the URL
+       * Message message = 2;   // mapped to the body
+       * }
+       * 
+       * The following HTTP JSON to RPC mapping is enabled, where the
+       * representation of the JSON in the request body is determined by
+       * protos JSON encoding:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+       * "123456" message { text: "Hi!" })`
+       * 
+       * The special name `*` can be used in the body mapping to define that
+       * every field not bound by the path template should be mapped to the
+       * request body.  This enables the following alternative definition of
+       * the update method:
+       * 
+       * service Messaging {
+       * rpc UpdateMessage(Message) returns (Message) {
+       * option (google.api.http) = {
+       * patch: "/v1/messages/{message_id}"
+       * body: "*"
+       * };
+       * }
+       * }
+       * message Message {
+       * string message_id = 1;
+       * string text = 2;
+       * }
+       * 
+       * 
+       * The following HTTP JSON to RPC mapping is enabled:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+       * "123456" text: "Hi!")`
+       * 
+       * Note that when using `*` in the body mapping, it is not possible to
+       * have HTTP parameters, as all fields not bound by the path end in
+       * the body. This makes this option more rarely used in practice when
+       * defining REST APIs. The common usage of `*` is in custom methods
+       * which don't use the URL at all for transferring data.
+       * 
+       * It is possible to define multiple HTTP methods for one RPC by using
+       * the `additional_bindings` option. Example:
+       * 
+       * service Messaging {
+       * rpc GetMessage(GetMessageRequest) returns (Message) {
+       * option (google.api.http) = {
+       * get: "/v1/messages/{message_id}"
+       * additional_bindings {
+       * get: "/v1/users/{user_id}/messages/{message_id}"
+       * }
+       * };
+       * }
+       * }
+       * message GetMessageRequest {
+       * string message_id = 1;
+       * string user_id = 2;
+       * }
+       * 
+       * This enables the following two alternative HTTP JSON to RPC mappings:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
+       * `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id:
+       * "123456")`
+       * 
+       * ## Rules for HTTP mapping
+       * 
+       * 1. Leaf request fields (recursive expansion nested messages in the request
+       * message) are classified into three categories:
+       * - Fields referred by the path template. They are passed via the URL path.
+       * - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They are passed via the HTTP
+       * request body.
+       * - All other fields are passed via the URL query parameters, and the
+       * parameter name is the field path in the request message. A repeated
+       * field can be represented as multiple query parameters under the same
+       * name.
+       * 2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields
+       * are passed via URL path and HTTP request body.
+       * 3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP request body, all
+       * fields are passed via URL path and URL query parameters.
+       * 
+       * ### Path template syntax
+       * 
+       * Template = "/" Segments [ Verb ] ;
+       * Segments = Segment { "/" Segment } ;
+       * Segment  = "*" | "**" | LITERAL | Variable ;
+       * Variable = "{" FieldPath [ "=" Segments ] "}" ;
+       * FieldPath = IDENT { "." IDENT } ;
+       * Verb     = ":" LITERAL ;
+       * 
+       * The syntax `*` matches a single URL path segment. The syntax `**` matches
+       * zero or more URL path segments, which must be the last part of the URL path
+       * except the `Verb`.
+       * 
+       * The syntax `Variable` matches part of the URL path as specified by its
+       * template. A variable template must not contain other variables. If a variable
+       * matches a single path segment, its template may be omitted, e.g. `{var}`
+       * is equivalent to `{var=*}`.
+       * 
+       * The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
+       * contains any reserved character, such characters should be percent-encoded
+       * before the matching.
+       * 
+       * If a variable contains exactly one path segment, such as `"{var}"` or
+       * `"{var=*}"`, when such a variable is expanded into a URL path on the client
+       * side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The
+       * server side does the reverse decoding. Such variables show up in the
+       * [Discovery
+       * Document](https://developers.google.com/discovery/v1/reference/apis) as
+       * `{var}`.
+       * 
+       * If a variable contains multiple path segments, such as `"{var=foo/*}"`
+       * or `"{var=**}"`, when such a variable is expanded into a URL path on the
+       * client side, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded.
+       * The server side does the reverse decoding, except "%2F" and "%2f" are left
+       * unchanged. Such variables show up in the
+       * [Discovery
+       * Document](https://developers.google.com/discovery/v1/reference/apis) as
+       * `{+var}`.
+       * 
+       * ## Using gRPC API Service Configuration
+       * 
+       * gRPC API Service Configuration (service config) is a configuration language
+       * for configuring a gRPC service to become a user-facing product. The
+       * service config is simply the YAML representation of the `google.api.Service`
+       * proto message.
+       * 
+       * As an alternative to annotating your proto file, you can configure gRPC
+       * transcoding in your service config YAML files. You do this by specifying a
+       * `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same
+       * effect as the proto annotation. This can be particularly useful if you
+       * have a proto that is reused in multiple services. Note that any transcoding
+       * specified in the service config will override any matching transcoding
+       * configuration in the proto.
+       * 
+       * Example:
+       * 
+       * http:
+       * rules:
+       * # Selects a gRPC method and applies HttpRule to it.
+       * - selector: example.v1.Messaging.GetMessage
+       * get: /v1/messages/{message_id}/{sub.subfield}
+       * 
+       * ## Special notes
+       * 
+       * When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
+       * proto to JSON conversion must follow the [proto3
+       * specification](https://developers.google.com/protocol-buffers/docs/proto3#json).
+       * 
+       * While the single segment variable follows the semantics of
+       * [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
+       * Expansion, the multi segment variable **does not** follow RFC 6570 Section
+       * 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
+       * does not expand special characters like `?` and `#`, which would lead
+       * to invalid URLs. As the result, gRPC Transcoding uses a custom encoding
+       * for multi segment variables.
+       * 
+       * The path variables **must not** refer to any repeated or mapped field,
+       * because client libraries are not capable of handling such variable expansion.
+       * 
+       * The path variables **must not** capture the leading "/" character. The reason
+       * is that the most common use case "{var}" does not capture the leading "/"
+       * character. For consistency, all path variables must share the same behavior.
+       * 
+       * Repeated message fields must not be mapped to URL query parameters, because
+       * no client library can support such complicated mapping.
+       * 
+       * If an API needs to use a JSON array for request or response body, it can map
+       * the request or response body to a repeated field. However, some gRPC
+       * Transcoding implementations may not support this feature.

+       * primitive type or a repeated primitive type or a non-repeated message type.
+       * In the case of a repeated type, the parameter can be repeated in the URL
+       * as `...?param=A&param=B`. In the case of a message type, each field of the
+       * message is mapped to a separate parameter, such as
+       * `...?foo.a=A&foo.b=B&foo.c=C`.
+       * 
+       * For HTTP methods that allow a request body, the `body` field
+       * specifies the mapping. Consider a REST update method on the
+       * message resource collection:
+       * 
+       * service Messaging {
+       * rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
+       * option (google.api.http) = {
+       * patch: "/v1/messages/{message_id}"
+       * body: "message"
+       * };
+       * }
+       * }
+       * message UpdateMessageRequest {
+       * string message_id = 1; // mapped to the URL
+       * Message message = 2;   // mapped to the body
+       * }
+       * 
+       * The following HTTP JSON to RPC mapping is enabled, where the
+       * representation of the JSON in the request body is determined by
+       * protos JSON encoding:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+       * "123456" message { text: "Hi!" })`
+       * 
+       * The special name `*` can be used in the body mapping to define that
+       * every field not bound by the path template should be mapped to the
+       * request body.  This enables the following alternative definition of
+       * the update method:
+       * 
+       * service Messaging {
+       * rpc UpdateMessage(Message) returns (Message) {
+       * option (google.api.http) = {
+       * patch: "/v1/messages/{message_id}"
+       * body: "*"
+       * };
+       * }
+       * }
+       * message Message {
+       * string message_id = 1;
+       * string text = 2;
+       * }
+       * 
+       * 
+       * The following HTTP JSON to RPC mapping is enabled:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+       * "123456" text: "Hi!")`
+       * 
+       * Note that when using `*` in the body mapping, it is not possible to
+       * have HTTP parameters, as all fields not bound by the path end in
+       * the body. This makes this option more rarely used in practice when
+       * defining REST APIs. The common usage of `*` is in custom methods
+       * which don't use the URL at all for transferring data.
+       * 
+       * It is possible to define multiple HTTP methods for one RPC by using
+       * the `additional_bindings` option. Example:
+       * 
+       * service Messaging {
+       * rpc GetMessage(GetMessageRequest) returns (Message) {
+       * option (google.api.http) = {
+       * get: "/v1/messages/{message_id}"
+       * additional_bindings {
+       * get: "/v1/users/{user_id}/messages/{message_id}"
+       * }
+       * };
+       * }
+       * }
+       * message GetMessageRequest {
+       * string message_id = 1;
+       * string user_id = 2;
+       * }
+       * 
+       * This enables the following two alternative HTTP JSON to RPC mappings:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
+       * `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id:
+       * "123456")`
+       * 
+       * ## Rules for HTTP mapping
+       * 
+       * 1. Leaf request fields (recursive expansion nested messages in the request
+       * message) are classified into three categories:
+       * - Fields referred by the path template. They are passed via the URL path.
+       * - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They are passed via the HTTP
+       * request body.
+       * - All other fields are passed via the URL query parameters, and the
+       * parameter name is the field path in the request message. A repeated
+       * field can be represented as multiple query parameters under the same
+       * name.
+       * 2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields
+       * are passed via URL path and HTTP request body.
+       * 3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP request body, all
+       * fields are passed via URL path and URL query parameters.
+       * 
+       * ### Path template syntax
+       * 
+       * Template = "/" Segments [ Verb ] ;
+       * Segments = Segment { "/" Segment } ;
+       * Segment  = "*" | "**" | LITERAL | Variable ;
+       * Variable = "{" FieldPath [ "=" Segments ] "}" ;
+       * FieldPath = IDENT { "." IDENT } ;
+       * Verb     = ":" LITERAL ;
+       * 
+       * The syntax `*` matches a single URL path segment. The syntax `**` matches
+       * zero or more URL path segments, which must be the last part of the URL path
+       * except the `Verb`.
+       * 
+       * The syntax `Variable` matches part of the URL path as specified by its
+       * template. A variable template must not contain other variables. If a variable
+       * matches a single path segment, its template may be omitted, e.g. `{var}`
+       * is equivalent to `{var=*}`.
+       * 
+       * The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
+       * contains any reserved character, such characters should be percent-encoded
+       * before the matching.
+       * 
+       * If a variable contains exactly one path segment, such as `"{var}"` or
+       * `"{var=*}"`, when such a variable is expanded into a URL path on the client
+       * side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The
+       * server side does the reverse decoding. Such variables show up in the
+       * [Discovery
+       * Document](https://developers.google.com/discovery/v1/reference/apis) as
+       * `{var}`.
+       * 
+       * If a variable contains multiple path segments, such as `"{var=foo/*}"`
+       * or `"{var=**}"`, when such a variable is expanded into a URL path on the
+       * client side, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded.
+       * The server side does the reverse decoding, except "%2F" and "%2f" are left
+       * unchanged. Such variables show up in the
+       * [Discovery
+       * Document](https://developers.google.com/discovery/v1/reference/apis) as
+       * `{+var}`.
+       * 
+       * ## Using gRPC API Service Configuration
+       * 
+       * gRPC API Service Configuration (service config) is a configuration language
+       * for configuring a gRPC service to become a user-facing product. The
+       * service config is simply the YAML representation of the `google.api.Service`
+       * proto message.
+       * 
+       * As an alternative to annotating your proto file, you can configure gRPC
+       * transcoding in your service config YAML files. You do this by specifying a
+       * `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same
+       * effect as the proto annotation. This can be particularly useful if you
+       * have a proto that is reused in multiple services. Note that any transcoding
+       * specified in the service config will override any matching transcoding
+       * configuration in the proto.
+       * 
+       * Example:
+       * 
+       * http:
+       * rules:
+       * # Selects a gRPC method and applies HttpRule to it.
+       * - selector: example.v1.Messaging.GetMessage
+       * get: /v1/messages/{message_id}/{sub.subfield}
+       * 
+       * ## Special notes
+       * 
+       * When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
+       * proto to JSON conversion must follow the [proto3
+       * specification](https://developers.google.com/protocol-buffers/docs/proto3#json).
+       * 
+       * While the single segment variable follows the semantics of
+       * [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
+       * Expansion, the multi segment variable **does not** follow RFC 6570 Section
+       * 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
+       * does not expand special characters like `?` and `#`, which would lead
+       * to invalid URLs. As the result, gRPC Transcoding uses a custom encoding
+       * for multi segment variables.
+       * 
+       * The path variables **must not** refer to any repeated or mapped field,
+       * because client libraries are not capable of handling such variable expansion.
+       * 
+       * The path variables **must not** capture the leading "/" character. The reason
+       * is that the most common use case "{var}" does not capture the leading "/"
+       * character. For consistency, all path variables must share the same behavior.
+       * 
+       * Repeated message fields must not be mapped to URL query parameters, because
+       * no client library can support such complicated mapping.
+       * 
+       * If an API needs to use a JSON array for request or response body, it can map
+       * the request or response body to a repeated field. However, some gRPC
+       * Transcoding implementations may not support this feature.

+ * A virtual cluster is a way of specifying a regex matching rule against
+ * certain important endpoints such that statistics are generated explicitly for
+ * the matched requests. The reason this is useful is that when doing
+ * prefix/path matching Envoy does not always know what the application
+ * considers to be an endpoint. Thus, it’s impossible for Envoy to generically
+ * emit per endpoint statistics. However, often systems have highly critical
+ * endpoints that they wish to get “perfect� statistics on. Virtual cluster
+ * statistics are perfect in the sense that they are emitted on the downstream
+ * side such that they include network level failures.
+ * 
+ * Documentation for :ref:`virtual cluster statistics <config_http_filters_router_vcluster_stats>`.
+ * 
+ * .. note::
+ * 
+ * Virtual clusters are a useful tool, but we do not recommend setting up a virtual cluster for
+ * every application endpoint. This is both not easily maintainable and as well the matching and
+ * statistics output are not free.

+ * # gRPC Transcoding
+ * 
+ * gRPC Transcoding is a feature for mapping between a gRPC method and one or
+ * more HTTP REST endpoints. It allows developers to build a single API service
+ * that supports both gRPC APIs and REST APIs. Many systems, including [Google
+ * APIs](https://github.com/googleapis/googleapis),
+ * [Cloud Endpoints](https://cloud.google.com/endpoints), [gRPC
+ * Gateway](https://github.com/grpc-ecosystem/grpc-gateway),
+ * and [Envoy](https://github.com/envoyproxy/envoy) proxy support this feature
+ * and use it for large scale production services.
+ * 
+ * `HttpRule` defines the schema of the gRPC/REST mapping. The mapping specifies
+ * how different portions of the gRPC request message are mapped to the URL
+ * path, URL query parameters, and HTTP request body. It also controls how the
+ * gRPC response message is mapped to the HTTP response body. `HttpRule` is
+ * typically specified as an `google.api.http` annotation on the gRPC method.
+ * 
+ * Each mapping specifies a URL path template and an HTTP method. The path
+ * template may refer to one or more fields in the gRPC request message, as long
+ * as each field is a non-repeated field with a primitive (non-message) type.
+ * The path template controls how fields of the request message are mapped to
+ * the URL path.
+ * 
+ * Example:
+ * 
+ * service Messaging {
+ * rpc GetMessage(GetMessageRequest) returns (Message) {
+ * option (google.api.http) = {
+ * get: "/v1/{name=messages/*}"
+ * };
+ * }
+ * }
+ * message GetMessageRequest {
+ * string name = 1; // Mapped to URL path.
+ * }
+ * message Message {
+ * string text = 1; // The resource content.
+ * }
+ * 
+ * This enables an HTTP REST to gRPC mapping as below:
+ * 
+ * HTTP | gRPC
+ * -----|-----
+ * `GET /v1/messages/123456`  | `GetMessage(name: "messages/123456")`
+ * 
+ * Any fields in the request message which are not bound by the path template
+ * automatically become HTTP query parameters if there is no HTTP request body.
+ * For example:
+ * 
+ * service Messaging {
+ * rpc GetMessage(GetMessageRequest) returns (Message) {
+ * option (google.api.http) = {
+ * get:"/v1/messages/{message_id}"
+ * };
+ * }
+ * }
+ * message GetMessageRequest {
+ * message SubMessage {
+ * string subfield = 1;
+ * }
+ * string message_id = 1; // Mapped to URL path.
+ * int64 revision = 2;    // Mapped to URL query parameter `revision`.
+ * SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
+ * }
+ * 
+ * This enables a HTTP JSON to RPC mapping as below:
+ * 
+ * HTTP | gRPC
+ * -----|-----
+ * `GET /v1/messages/123456?revision=2&sub.subfield=foo` |
+ * `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield:
+ * "foo"))`
+ * 
+ * Note that fields which are mapped to URL query parameters must have a
+ * primitive type or a repeated primitive type or a non-repeated message type.
+ * In the case of a repeated type, the parameter can be repeated in the URL
+ * as `...?param=A&param=B`. In the case of a message type, each field of the
+ * message is mapped to a separate parameter, such as
+ * `...?foo.a=A&foo.b=B&foo.c=C`.
+ * 
+ * For HTTP methods that allow a request body, the `body` field
+ * specifies the mapping. Consider a REST update method on the
+ * message resource collection:
+ * 
+ * service Messaging {
+ * rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
+ * option (google.api.http) = {
+ * patch: "/v1/messages/{message_id}"
+ * body: "message"
+ * };
+ * }
+ * }
+ * message UpdateMessageRequest {
+ * string message_id = 1; // mapped to the URL
+ * Message message = 2;   // mapped to the body
+ * }
+ * 
+ * The following HTTP JSON to RPC mapping is enabled, where the
+ * representation of the JSON in the request body is determined by
+ * protos JSON encoding:
+ * 
+ * HTTP | gRPC
+ * -----|-----
+ * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+ * "123456" message { text: "Hi!" })`
+ * 
+ * The special name `*` can be used in the body mapping to define that
+ * every field not bound by the path template should be mapped to the
+ * request body.  This enables the following alternative definition of
+ * the update method:
+ * 
+ * service Messaging {
+ * rpc UpdateMessage(Message) returns (Message) {
+ * option (google.api.http) = {
+ * patch: "/v1/messages/{message_id}"
+ * body: "*"
+ * };
+ * }
+ * }
+ * message Message {
+ * string message_id = 1;
+ * string text = 2;
+ * }
+ * 
+ * 
+ * The following HTTP JSON to RPC mapping is enabled:
+ * 
+ * HTTP | gRPC
+ * -----|-----
+ * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+ * "123456" text: "Hi!")`
+ * 
+ * Note that when using `*` in the body mapping, it is not possible to
+ * have HTTP parameters, as all fields not bound by the path end in
+ * the body. This makes this option more rarely used in practice when
+ * defining REST APIs. The common usage of `*` is in custom methods
+ * which don't use the URL at all for transferring data.
+ * 
+ * It is possible to define multiple HTTP methods for one RPC by using
+ * the `additional_bindings` option. Example:
+ * 
+ * service Messaging {
+ * rpc GetMessage(GetMessageRequest) returns (Message) {
+ * option (google.api.http) = {
+ * get: "/v1/messages/{message_id}"
+ * additional_bindings {
+ * get: "/v1/users/{user_id}/messages/{message_id}"
+ * }
+ * };
+ * }
+ * }
+ * message GetMessageRequest {
+ * string message_id = 1;
+ * string user_id = 2;
+ * }
+ * 
+ * This enables the following two alternative HTTP JSON to RPC mappings:
+ * 
+ * HTTP | gRPC
+ * -----|-----
+ * `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
+ * `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id:
+ * "123456")`
+ * 
+ * ## Rules for HTTP mapping
+ * 
+ * 1. Leaf request fields (recursive expansion nested messages in the request
+ * message) are classified into three categories:
+ * - Fields referred by the path template. They are passed via the URL path.
+ * - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They are passed via the HTTP
+ * request body.
+ * - All other fields are passed via the URL query parameters, and the
+ * parameter name is the field path in the request message. A repeated
+ * field can be represented as multiple query parameters under the same
+ * name.
+ * 2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields
+ * are passed via URL path and HTTP request body.
+ * 3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP request body, all
+ * fields are passed via URL path and URL query parameters.
+ * 
+ * ### Path template syntax
+ * 
+ * Template = "/" Segments [ Verb ] ;
+ * Segments = Segment { "/" Segment } ;
+ * Segment  = "*" | "**" | LITERAL | Variable ;
+ * Variable = "{" FieldPath [ "=" Segments ] "}" ;
+ * FieldPath = IDENT { "." IDENT } ;
+ * Verb     = ":" LITERAL ;
+ * 
+ * The syntax `*` matches a single URL path segment. The syntax `**` matches
+ * zero or more URL path segments, which must be the last part of the URL path
+ * except the `Verb`.
+ * 
+ * The syntax `Variable` matches part of the URL path as specified by its
+ * template. A variable template must not contain other variables. If a variable
+ * matches a single path segment, its template may be omitted, e.g. `{var}`
+ * is equivalent to `{var=*}`.
+ * 
+ * The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
+ * contains any reserved character, such characters should be percent-encoded
+ * before the matching.
+ * 
+ * If a variable contains exactly one path segment, such as `"{var}"` or
+ * `"{var=*}"`, when such a variable is expanded into a URL path on the client
+ * side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The
+ * server side does the reverse decoding. Such variables show up in the
+ * [Discovery
+ * Document](https://developers.google.com/discovery/v1/reference/apis) as
+ * `{var}`.
+ * 
+ * If a variable contains multiple path segments, such as `"{var=foo/*}"`
+ * or `"{var=**}"`, when such a variable is expanded into a URL path on the
+ * client side, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded.
+ * The server side does the reverse decoding, except "%2F" and "%2f" are left
+ * unchanged. Such variables show up in the
+ * [Discovery
+ * Document](https://developers.google.com/discovery/v1/reference/apis) as
+ * `{+var}`.
+ * 
+ * ## Using gRPC API Service Configuration
+ * 
+ * gRPC API Service Configuration (service config) is a configuration language
+ * for configuring a gRPC service to become a user-facing product. The
+ * service config is simply the YAML representation of the `google.api.Service`
+ * proto message.
+ * 
+ * As an alternative to annotating your proto file, you can configure gRPC
+ * transcoding in your service config YAML files. You do this by specifying a
+ * `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same
+ * effect as the proto annotation. This can be particularly useful if you
+ * have a proto that is reused in multiple services. Note that any transcoding
+ * specified in the service config will override any matching transcoding
+ * configuration in the proto.
+ * 
+ * Example:
+ * 
+ * http:
+ * rules:
+ * # Selects a gRPC method and applies HttpRule to it.
+ * - selector: example.v1.Messaging.GetMessage
+ * get: /v1/messages/{message_id}/{sub.subfield}
+ * 
+ * ## Special notes
+ * 
+ * When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
+ * proto to JSON conversion must follow the [proto3
+ * specification](https://developers.google.com/protocol-buffers/docs/proto3#json).
+ * 
+ * While the single segment variable follows the semantics of
+ * [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
+ * Expansion, the multi segment variable **does not** follow RFC 6570 Section
+ * 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
+ * does not expand special characters like `?` and `#`, which would lead
+ * to invalid URLs. As the result, gRPC Transcoding uses a custom encoding
+ * for multi segment variables.
+ * 
+ * The path variables **must not** refer to any repeated or mapped field,
+ * because client libraries are not capable of handling such variable expansion.
+ * 
+ * The path variables **must not** capture the leading "/" character. The reason
+ * is that the most common use case "{var}" does not capture the leading "/"
+ * character. For consistency, all path variables must share the same behavior.
+ * 
+ * Repeated message fields must not be mapped to URL query parameters, because
+ * no client library can support such complicated mapping.
+ * 
+ * If an API needs to use a JSON array for request or response body, it can map
+ * the request or response body to a repeated field. However, some gRPC
+ * Transcoding implementations may not support this feature.

+       * that supports both gRPC APIs and REST APIs. Many systems, including [Google
+       * APIs](https://github.com/googleapis/googleapis),
+       * [Cloud Endpoints](https://cloud.google.com/endpoints), [gRPC
+       * Gateway](https://github.com/grpc-ecosystem/grpc-gateway),
+       * and [Envoy](https://github.com/envoyproxy/envoy) proxy support this feature
+       * and use it for large scale production services.
+       * 
+       * `HttpRule` defines the schema of the gRPC/REST mapping. The mapping specifies
+       * how different portions of the gRPC request message are mapped to the URL
+       * path, URL query parameters, and HTTP request body. It also controls how the
+       * gRPC response message is mapped to the HTTP response body. `HttpRule` is
+       * typically specified as an `google.api.http` annotation on the gRPC method.
+       * 
+       * Each mapping specifies a URL path template and an HTTP method. The path
+       * template may refer to one or more fields in the gRPC request message, as long
+       * as each field is a non-repeated field with a primitive (non-message) type.
+       * The path template controls how fields of the request message are mapped to
+       * the URL path.
+       * 
+       * Example:
+       * 
+       * service Messaging {
+       * rpc GetMessage(GetMessageRequest) returns (Message) {
+       * option (google.api.http) = {
+       * get: "/v1/{name=messages/*}"
+       * };
+       * }
+       * }
+       * message GetMessageRequest {
+       * string name = 1; // Mapped to URL path.
+       * }
+       * message Message {
+       * string text = 1; // The resource content.
+       * }
+       * 
+       * This enables an HTTP REST to gRPC mapping as below:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `GET /v1/messages/123456`  | `GetMessage(name: "messages/123456")`
+       * 
+       * Any fields in the request message which are not bound by the path template
+       * automatically become HTTP query parameters if there is no HTTP request body.
+       * For example:
+       * 
+       * service Messaging {
+       * rpc GetMessage(GetMessageRequest) returns (Message) {
+       * option (google.api.http) = {
+       * get:"/v1/messages/{message_id}"
+       * };
+       * }
+       * }
+       * message GetMessageRequest {
+       * message SubMessage {
+       * string subfield = 1;
+       * }
+       * string message_id = 1; // Mapped to URL path.
+       * int64 revision = 2;    // Mapped to URL query parameter `revision`.
+       * SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
+       * }
+       * 
+       * This enables a HTTP JSON to RPC mapping as below:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `GET /v1/messages/123456?revision=2&sub.subfield=foo` |
+       * `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield:
+       * "foo"))`
+       * 
+       * Note that fields which are mapped to URL query parameters must have a
+       * primitive type or a repeated primitive type or a non-repeated message type.
+       * In the case of a repeated type, the parameter can be repeated in the URL
+       * as `...?param=A&param=B`. In the case of a message type, each field of the
+       * message is mapped to a separate parameter, such as
+       * `...?foo.a=A&foo.b=B&foo.c=C`.
+       * 
+       * For HTTP methods that allow a request body, the `body` field
+       * specifies the mapping. Consider a REST update method on the
+       * message resource collection:
+       * 
+       * service Messaging {
+       * rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
+       * option (google.api.http) = {
+       * patch: "/v1/messages/{message_id}"
+       * body: "message"
+       * };
+       * }
+       * }
+       * message UpdateMessageRequest {
+       * string message_id = 1; // mapped to the URL
+       * Message message = 2;   // mapped to the body
+       * }
+       * 
+       * The following HTTP JSON to RPC mapping is enabled, where the
+       * representation of the JSON in the request body is determined by
+       * protos JSON encoding:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+       * "123456" message { text: "Hi!" })`
+       * 
+       * The special name `*` can be used in the body mapping to define that
+       * every field not bound by the path template should be mapped to the
+       * request body.  This enables the following alternative definition of
+       * the update method:
+       * 
+       * service Messaging {
+       * rpc UpdateMessage(Message) returns (Message) {
+       * option (google.api.http) = {
+       * patch: "/v1/messages/{message_id}"
+       * body: "*"
+       * };
+       * }
+       * }
+       * message Message {
+       * string message_id = 1;
+       * string text = 2;
+       * }
+       * 
+       * 
+       * The following HTTP JSON to RPC mapping is enabled:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+       * "123456" text: "Hi!")`
+       * 
+       * Note that when using `*` in the body mapping, it is not possible to
+       * have HTTP parameters, as all fields not bound by the path end in
+       * the body. This makes this option more rarely used in practice when
+       * defining REST APIs. The common usage of `*` is in custom methods
+       * which don't use the URL at all for transferring data.
+       * 
+       * It is possible to define multiple HTTP methods for one RPC by using
+       * the `additional_bindings` option. Example:
+       * 
+       * service Messaging {
+       * rpc GetMessage(GetMessageRequest) returns (Message) {
+       * option (google.api.http) = {
+       * get: "/v1/messages/{message_id}"
+       * additional_bindings {
+       * get: "/v1/users/{user_id}/messages/{message_id}"
+       * }
+       * };
+       * }
+       * }
+       * message GetMessageRequest {
+       * string message_id = 1;
+       * string user_id = 2;
+       * }
+       * 
+       * This enables the following two alternative HTTP JSON to RPC mappings:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
+       * `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id:
+       * "123456")`
+       * 
+       * ## Rules for HTTP mapping
+       * 
+       * 1. Leaf request fields (recursive expansion nested messages in the request
+       * message) are classified into three categories:
+       * - Fields referred by the path template. They are passed via the URL path.
+       * - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They are passed via the HTTP
+       * request body.
+       * - All other fields are passed via the URL query parameters, and the
+       * parameter name is the field path in the request message. A repeated
+       * field can be represented as multiple query parameters under the same
+       * name.
+       * 2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields
+       * are passed via URL path and HTTP request body.
+       * 3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP request body, all
+       * fields are passed via URL path and URL query parameters.
+       * 
+       * ### Path template syntax
+       * 
+       * Template = "/" Segments [ Verb ] ;
+       * Segments = Segment { "/" Segment } ;
+       * Segment  = "*" | "**" | LITERAL | Variable ;
+       * Variable = "{" FieldPath [ "=" Segments ] "}" ;
+       * FieldPath = IDENT { "." IDENT } ;
+       * Verb     = ":" LITERAL ;
+       * 
+       * The syntax `*` matches a single URL path segment. The syntax `**` matches
+       * zero or more URL path segments, which must be the last part of the URL path
+       * except the `Verb`.
+       * 
+       * The syntax `Variable` matches part of the URL path as specified by its
+       * template. A variable template must not contain other variables. If a variable
+       * matches a single path segment, its template may be omitted, e.g. `{var}`
+       * is equivalent to `{var=*}`.
+       * 
+       * The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
+       * contains any reserved character, such characters should be percent-encoded
+       * before the matching.
+       * 
+       * If a variable contains exactly one path segment, such as `"{var}"` or
+       * `"{var=*}"`, when such a variable is expanded into a URL path on the client
+       * side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The
+       * server side does the reverse decoding. Such variables show up in the
+       * [Discovery
+       * Document](https://developers.google.com/discovery/v1/reference/apis) as
+       * `{var}`.
+       * 
+       * If a variable contains multiple path segments, such as `"{var=foo/*}"`

+       * ## Using gRPC API Service Configuration
+       * 
+       * gRPC API Service Configuration (service config) is a configuration language
+       * for configuring a gRPC service to become a user-facing product. The
+       * service config is simply the YAML representation of the `google.api.Service`
+       * proto message.
+       * 
+       * As an alternative to annotating your proto file, you can configure gRPC
+       * transcoding in your service config YAML files. You do this by specifying a
+       * `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same
+       * effect as the proto annotation. This can be particularly useful if you
+       * have a proto that is reused in multiple services. Note that any transcoding
+       * specified in the service config will override any matching transcoding
+       * configuration in the proto.
+       * 
+       * Example:
+       * 
+       * http:
+       * rules:
+       * # Selects a gRPC method and applies HttpRule to it.
+       * - selector: example.v1.Messaging.GetMessage
+       * get: /v1/messages/{message_id}/{sub.subfield}
+       * 
+       * ## Special notes
+       * 
+       * When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
+       * proto to JSON conversion must follow the [proto3
+       * specification](https://developers.google.com/protocol-buffers/docs/proto3#json).
+       * 
+       * While the single segment variable follows the semantics of
+       * [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
+       * Expansion, the multi segment variable **does not** follow RFC 6570 Section
+       * 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
+       * does not expand special characters like `?` and `#`, which would lead
+       * to invalid URLs. As the result, gRPC Transcoding uses a custom encoding
+       * for multi segment variables.
+       * 
+       * The path variables **must not** refer to any repeated or mapped field,
+       * because client libraries are not capable of handling such variable expansion.
+       * 
+       * The path variables **must not** capture the leading "/" character. The reason
+       * is that the most common use case "{var}" does not capture the leading "/"
+       * character. For consistency, all path variables must share the same behavior.
+       * 
+       * Repeated message fields must not be mapped to URL query parameters, because
+       * no client library can support such complicated mapping.
+       * 
+       * If an API needs to use a JSON array for request or response body, it can map
+       * the request or response body to a repeated field. However, some gRPC
+       * Transcoding implementations may not support this feature.
+       */
       export type HttpRule = _google_api_HttpRule;
+      /**
+       * # gRPC Transcoding
+       * 
+       * gRPC Transcoding is a feature for mapping between a gRPC method and one or
+       * more HTTP REST endpoints. It allows developers to build a single API service
+       * that supports both gRPC APIs and REST APIs. Many systems, including [Google
+       * APIs](https://github.com/googleapis/googleapis),
+       * [Cloud Endpoints](https://cloud.google.com/endpoints), [gRPC
+       * Gateway](https://github.com/grpc-ecosystem/grpc-gateway),
+       * and [Envoy](https://github.com/envoyproxy/envoy) proxy support this feature
+       * and use it for large scale production services.
+       * 
+       * `HttpRule` defines the schema of the gRPC/REST mapping. The mapping specifies
+       * how different portions of the gRPC request message are mapped to the URL
+       * path, URL query parameters, and HTTP request body. It also controls how the
+       * gRPC response message is mapped to the HTTP response body. `HttpRule` is
+       * typically specified as an `google.api.http` annotation on the gRPC method.
+       * 
+       * Each mapping specifies a URL path template and an HTTP method. The path
+       * template may refer to one or more fields in the gRPC request message, as long
+       * as each field is a non-repeated field with a primitive (non-message) type.
+       * The path template controls how fields of the request message are mapped to
+       * the URL path.
+       * 
+       * Example:
+       * 
+       * service Messaging {
+       * rpc GetMessage(GetMessageRequest) returns (Message) {
+       * option (google.api.http) = {
+       * get: "/v1/{name=messages/*}"
+       * };
+       * }
+       * }
+       * message GetMessageRequest {
+       * string name = 1; // Mapped to URL path.
+       * }
+       * message Message {
+       * string text = 1; // The resource content.
+       * }
+       * 
+       * This enables an HTTP REST to gRPC mapping as below:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `GET /v1/messages/123456`  | `GetMessage(name: "messages/123456")`
+       * 
+       * Any fields in the request message which are not bound by the path template
+       * automatically become HTTP query parameters if there is no HTTP request body.
+       * For example:
+       * 
+       * service Messaging {
+       * rpc GetMessage(GetMessageRequest) returns (Message) {
+       * option (google.api.http) = {
+       * get:"/v1/messages/{message_id}"
+       * };
+       * }
+       * }
+       * message GetMessageRequest {
+       * message SubMessage {
+       * string subfield = 1;
+       * }
+       * string message_id = 1; // Mapped to URL path.
+       * int64 revision = 2;    // Mapped to URL query parameter `revision`.
+       * SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
+       * }
+       * 
+       * This enables a HTTP JSON to RPC mapping as below:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `GET /v1/messages/123456?revision=2&sub.subfield=foo` |
+       * `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield:
+       * "foo"))`
+       * 
+       * Note that fields which are mapped to URL query parameters must have a
+       * primitive type or a repeated primitive type or a non-repeated message type.
+       * In the case of a repeated type, the parameter can be repeated in the URL
+       * as `...?param=A&param=B`. In the case of a message type, each field of the
+       * message is mapped to a separate parameter, such as
+       * `...?foo.a=A&foo.b=B&foo.c=C`.
+       * 
+       * For HTTP methods that allow a request body, the `body` field
+       * specifies the mapping. Consider a REST update method on the
+       * message resource collection:
+       * 
+       * service Messaging {
+       * rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
+       * option (google.api.http) = {
+       * patch: "/v1/messages/{message_id}"
+       * body: "message"
+       * };
+       * }
+       * }
+       * message UpdateMessageRequest {
+       * string message_id = 1; // mapped to the URL
+       * Message message = 2;   // mapped to the body
+       * }
+       * 
+       * The following HTTP JSON to RPC mapping is enabled, where the
+       * representation of the JSON in the request body is determined by
+       * protos JSON encoding:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+       * "123456" message { text: "Hi!" })`
+       * 
+       * The special name `*` can be used in the body mapping to define that
+       * every field not bound by the path template should be mapped to the
+       * request body.  This enables the following alternative definition of
+       * the update method:
+       * 
+       * service Messaging {
+       * rpc UpdateMessage(Message) returns (Message) {
+       * option (google.api.http) = {
+       * patch: "/v1/messages/{message_id}"
+       * body: "*"
+       * };
+       * }
+       * }
+       * message Message {
+       * string message_id = 1;
+       * string text = 2;
+       * }
+       * 
+       * 
+       * The following HTTP JSON to RPC mapping is enabled:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+       * "123456" text: "Hi!")`
+       * 
+       * Note that when using `*` in the body mapping, it is not possible to
+       * have HTTP parameters, as all fields not bound by the path end in
+       * the body. This makes this option more rarely used in practice when
+       * defining REST APIs. The common usage of `*` is in custom methods
+       * which don't use the URL at all for transferring data.
+       * 
+       * It is possible to define multiple HTTP methods for one RPC by using
+       * the `additional_bindings` option. Example:
+       * 
+       * service Messaging {
+       * rpc GetMessage(GetMessageRequest) returns (Message) {
+       * option (google.api.http) = {
+       * get: "/v1/messages/{message_id}"
+       * additional_bindings {
+       * get: "/v1/users/{user_id}/messages/{message_id}"
+       * }
+       * };
+       * }
+       * }
+       * message GetMessageRequest {
+       * string message_id = 1;
+       * string user_id = 2;
+       * }
+       * 
+       * This enables the following two alternative HTTP JSON to RPC mappings:
+       * 
+       * HTTP | gRPC
+       * -----|-----
+       * `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
+       * `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id:
+       * "123456")`
+       * 
+       * ## Rules for HTTP mapping
+       * 
+       * 1. Leaf request fields (recursive expansion nested messages in the request
+       * message) are classified into three categories:
+       * - Fields referred by the path template. They are passed via the URL path.
+       * - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They are passed via the HTTP
+       * request body.
+       * - All other fields are passed via the URL query parameters, and the
+       * parameter name is the field path in the request message. A repeated
+       * field can be represented as multiple query parameters under the same
+       * name.
+       * 2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields
+       * are passed via URL path and HTTP request body.
+       * 3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP request body, all
+       * fields are passed via URL path and URL query parameters.
+       * 
+       * ### Path template syntax
+       * 
+       * Template = "/" Segments [ Verb ] ;
+       * Segments = Segment { "/" Segment } ;
+       * Segment  = "*" | "**" | LITERAL | Variable ;
+       * Variable = "{" FieldPath [ "=" Segments ] "}" ;
+       * FieldPath = IDENT { "." IDENT } ;
+       * Verb     = ":" LITERAL ;
+       * 
+       * The syntax `*` matches a single URL path segment. The syntax `**` matches
+       * zero or more URL path segments, which must be the last part of the URL path
+       * except the `Verb`.
+       * 
+       * The syntax `Variable` matches part of the URL path as specified by its
+       * template. A variable template must not contain other variables. If a variable
+       * matches a single path segment, its template may be omitted, e.g. `{var}`
+       * is equivalent to `{var=*}`.
+       * 
+       * The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
+       * contains any reserved character, such characters should be percent-encoded
+       * before the matching.
+       * 
+       * If a variable contains exactly one path segment, such as `"{var}"` or
+       * `"{var=*}"`, when such a variable is expanded into a URL path on the client
+       * side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The
+       * server side does the reverse decoding. Such variables show up in the
+       * [Discovery
+       * Document](https://developers.google.com/discovery/v1/reference/apis) as
+       * `{var}`.
+       * 
+       * If a variable contains multiple path segments, such as `"{var=foo/*}"`
+       * or `"{var=**}"`, when such a variable is expanded into a URL path on the
+       * client side, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded.
+       * The server side does the reverse decoding, except "%2F" and "%2f" are left
+       * unchanged. Such variables show up in the
+       * [Discovery
+       * Document](https://developers.google.com/discovery/v1/reference/apis) as
+       * `{+var}`.
+       * 
+       * ## Using gRPC API Service Configuration

-       * gRPC Transcoding is a feature for mapping between a gRPC method and one or
-       * more HTTP REST endpoints. It allows developers to build a single API service
-       * that supports both gRPC APIs and REST APIs. Many systems, including [Google
-       * APIs](https://github.com/googleapis/googleapis),
-       * [Cloud Endpoints](https://cloud.google.com/endpoints), [gRPC
-       * Gateway](https://github.com/grpc-ecosystem/grpc-gateway),
-       * and [Envoy](https://github.com/envoyproxy/envoy) proxy support this feature
-       * and use it for large scale production services.
-       * 
-       * `HttpRule` defines the schema of the gRPC/REST mapping. The mapping specifies
-       * how different portions of the gRPC request message are mapped to the URL
-       * path, URL query parameters, and HTTP request body. It also controls how the
-       * gRPC response message is mapped to the HTTP response body. `HttpRule` is
-       * typically specified as an `google.api.http` annotation on the gRPC method.
-       * 
-       * Each mapping specifies a URL path template and an HTTP method. The path
-       * template may refer to one or more fields in the gRPC request message, as long
-       * as each field is a non-repeated field with a primitive (non-message) type.
-       * The path template controls how fields of the request message are mapped to
-       * the URL path.
-       * 
-       * Example:
-       * 
-       * service Messaging {
-       * rpc GetMessage(GetMessageRequest) returns (Message) {
-       * option (google.api.http) = {
-       * get: "/v1/{name=messages/*}"
-       * };
-       * }
-       * }
-       * message GetMessageRequest {
-       * string name = 1; // Mapped to URL path.
-       * }
-       * message Message {
-       * string text = 1; // The resource content.
-       * }
-       * 
-       * This enables an HTTP REST to gRPC mapping as below:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `GET /v1/messages/123456`  | `GetMessage(name: "messages/123456")`
-       * 
-       * Any fields in the request message which are not bound by the path template
-       * automatically become HTTP query parameters if there is no HTTP request body.
-       * For example:
-       * 
-       * service Messaging {
-       * rpc GetMessage(GetMessageRequest) returns (Message) {
-       * option (google.api.http) = {
-       * get:"/v1/messages/{message_id}"
-       * };
-       * }
-       * }
-       * message GetMessageRequest {
-       * message SubMessage {
-       * string subfield = 1;
-       * }
-       * string message_id = 1; // Mapped to URL path.
-       * int64 revision = 2;    // Mapped to URL query parameter `revision`.
-       * SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
-       * }
-       * 
-       * This enables a HTTP JSON to RPC mapping as below:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `GET /v1/messages/123456?revision=2&sub.subfield=foo` |
-       * `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield:
-       * "foo"))`
-       * 
-       * Note that fields which are mapped to URL query parameters must have a
-       * primitive type or a repeated primitive type or a non-repeated message type.
-       * In the case of a repeated type, the parameter can be repeated in the URL
-       * as `...?param=A&param=B`. In the case of a message type, each field of the
-       * message is mapped to a separate parameter, such as
-       * `...?foo.a=A&foo.b=B&foo.c=C`.
-       * 
-       * For HTTP methods that allow a request body, the `body` field
-       * specifies the mapping. Consider a REST update method on the
-       * message resource collection:
-       * 
-       * service Messaging {
-       * rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
-       * option (google.api.http) = {
-       * patch: "/v1/messages/{message_id}"
-       * body: "message"
-       * };
-       * }
-       * }
-       * message UpdateMessageRequest {
-       * string message_id = 1; // mapped to the URL
-       * Message message = 2;   // mapped to the body
-       * }
-       * 
-       * The following HTTP JSON to RPC mapping is enabled, where the
-       * representation of the JSON in the request body is determined by
-       * protos JSON encoding:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
-       * "123456" message { text: "Hi!" })`
-       * 
-       * The special name `*` can be used in the body mapping to define that
-       * every field not bound by the path template should be mapped to the
-       * request body.  This enables the following alternative definition of
-       * the update method:
-       * 
-       * service Messaging {
-       * rpc UpdateMessage(Message) returns (Message) {
-       * option (google.api.http) = {
-       * patch: "/v1/messages/{message_id}"
-       * body: "*"
-       * };
-       * }
-       * }
-       * message Message {
-       * string message_id = 1;
-       * string text = 2;
-       * }
-       * 
-       * 
-       * The following HTTP JSON to RPC mapping is enabled:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
-       * "123456" text: "Hi!")`
-       * 
-       * Note that when using `*` in the body mapping, it is not possible to
-       * have HTTP parameters, as all fields not bound by the path end in
-       * the body. This makes this option more rarely used in practice when
-       * defining REST APIs. The common usage of `*` is in custom methods
-       * which don't use the URL at all for transferring data.
-       * 
-       * It is possible to define multiple HTTP methods for one RPC by using
-       * the `additional_bindings` option. Example:
-       * 
-       * service Messaging {
-       * rpc GetMessage(GetMessageRequest) returns (Message) {
-       * option (google.api.http) = {
-       * get: "/v1/messages/{message_id}"
-       * additional_bindings {
-       * get: "/v1/users/{user_id}/messages/{message_id}"
-       * }
-       * };
-       * }
-       * }
-       * message GetMessageRequest {
-       * string message_id = 1;
-       * string user_id = 2;
-       * }
-       * 
-       * This enables the following two alternative HTTP JSON to RPC mappings:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
-       * `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id:
-       * "123456")`
-       * 
-       * ## Rules for HTTP mapping
-       * 
-       * 1. Leaf request fields (recursive expansion nested messages in the request
-       * message) are classified into three categories:
-       * - Fields referred by the path template. They are passed via the URL path.
-       * - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They are passed via the HTTP
-       * request body.
-       * - All other fields are passed via the URL query parameters, and the
-       * parameter name is the field path in the request message. A repeated
-       * field can be represented as multiple query parameters under the same
-       * name.
-       * 2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields
-       * are passed via URL path and HTTP request body.
-       * 3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP request body, all
-       * fields are passed via URL path and URL query parameters.
-       * 
-       * ### Path template syntax
-       * 
-       * Template = "/" Segments [ Verb ] ;
-       * Segments = Segment { "/" Segment } ;
-       * Segment  = "*" | "**" | LITERAL | Variable ;
-       * Variable = "{" FieldPath [ "=" Segments ] "}" ;
-       * FieldPath = IDENT { "." IDENT } ;
-       * Verb     = ":" LITERAL ;
-       * 
-       * The syntax `*` matches a single URL path segment. The syntax `**` matches
-       * zero or more URL path segments, which must be the last part of the URL path
-       * except the `Verb`.
-       * 
-       * The syntax `Variable` matches part of the URL path as specified by its
-       * template. A variable template must not contain other variables. If a variable
-       * matches a single path segment, its template may be omitted, e.g. `{var}`
-       * is equivalent to `{var=*}`.
-       * 
-       * The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
-       * contains any reserved character, such characters should be percent-encoded
-       * before the matching.
-       * 
-       * If a variable contains exactly one path segment, such as `"{var}"` or
-       * `"{var=*}"`, when such a variable is expanded into a URL path on the client
-       * side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The

-       * Document](https://developers.google.com/discovery/v1/reference/apis) as

-       *

-       * or `"{var=**}"`, when such a variable is expanded into a URL path on the

-       * ## Using gRPC API Service Configuration
-       * 
-       * gRPC API Service Configuration (service config) is a configuration language
-       * for configuring a gRPC service to become a user-facing product. The
-       * service config is simply the YAML representation of the `google.api.Service`
-       * proto message.
-       * 
-       * As an alternative to annotating your proto file, you can configure gRPC
-       * transcoding in your service config YAML files. You do this by specifying a
-       * `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same
-       * effect as the proto annotation. This can be particularly useful if you
-       * have a proto that is reused in multiple services. Note that any transcoding
-       * specified in the service config will override any matching transcoding
-       * configuration in the proto.
-       * 
-       * Example:
-       * 
-       * http:
-       * rules:
-       * # Selects a gRPC method and applies HttpRule to it.
-       * - selector: example.v1.Messaging.GetMessage
-       * get: /v1/messages/{message_id}/{sub.subfield}
-       * 
-       * ## Special notes
-       * 
-       * When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
-       * proto to JSON conversion must follow the [proto3
-       * specification](https://developers.google.com/protocol-buffers/docs/proto3#json).
-       * 
-       * While the single segment variable follows the semantics of
-       * [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
-       * Expansion, the multi segment variable **does not** follow RFC 6570 Section
-       * 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
-       * does not expand special characters like `?` and `#`, which would lead
-       * to invalid URLs. As the result, gRPC Transcoding uses a custom encoding
-       * for multi segment variables.
-       * 
-       * The path variables **must not** refer to any repeated or mapped field,
-       * because client libraries are not capable of handling such variable expansion.
-       * 
-       * The path variables **must not** capture the leading "/" character. The reason
-       * is that the most common use case "{var}" does not capture the leading "/"
-       * character. For consistency, all path variables must share the same behavior.
-       * 
-       * Repeated message fields must not be mapped to URL query parameters, because
-       * no client library can support such complicated mapping.
-       * 
-       * If an API needs to use a JSON array for request or response body, it can map
-       * the request or response body to a repeated field. However, some gRPC
-       * Transcoding implementations may not support this feature.

-      export type HttpRule = _google_api_HttpRule;
-      /**
-       * # gRPC Transcoding
-       * 
-       * gRPC Transcoding is a feature for mapping between a gRPC method and one or
-       * more HTTP REST endpoints. It allows developers to build a single API service
-       * that supports both gRPC APIs and REST APIs. Many systems, including [Google
-       * APIs](https://github.com/googleapis/googleapis),
-       * [Cloud Endpoints](https://cloud.google.com/endpoints), [gRPC
-       * Gateway](https://github.com/grpc-ecosystem/grpc-gateway),
-       * and [Envoy](https://github.com/envoyproxy/envoy) proxy support this feature
-       * and use it for large scale production services.
-       * 
-       * `HttpRule` defines the schema of the gRPC/REST mapping. The mapping specifies
-       * how different portions of the gRPC request message are mapped to the URL
-       * path, URL query parameters, and HTTP request body. It also controls how the
-       * gRPC response message is mapped to the HTTP response body. `HttpRule` is
-       * typically specified as an `google.api.http` annotation on the gRPC method.
-       * 
-       * Each mapping specifies a URL path template and an HTTP method. The path
-       * template may refer to one or more fields in the gRPC request message, as long
-       * as each field is a non-repeated field with a primitive (non-message) type.
-       * The path template controls how fields of the request message are mapped to
-       * the URL path.
-       * 
-       * Example:
-       * 
-       * service Messaging {
-       * rpc GetMessage(GetMessageRequest) returns (Message) {
-       * option (google.api.http) = {
-       * get: "/v1/{name=messages/*}"
-       * };
-       * }
-       * }
-       * message GetMessageRequest {
-       * string name = 1; // Mapped to URL path.
-       * }
-       * message Message {
-       * string text = 1; // The resource content.
-       * }
-       * 
-       * This enables an HTTP REST to gRPC mapping as below:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `GET /v1/messages/123456`  | `GetMessage(name: "messages/123456")`
-       * 
-       * Any fields in the request message which are not bound by the path template
-       * automatically become HTTP query parameters if there is no HTTP request body.
-       * For example:
-       * 
-       * service Messaging {
-       * rpc GetMessage(GetMessageRequest) returns (Message) {
-       * option (google.api.http) = {
-       * get:"/v1/messages/{message_id}"
-       * };
-       * }
-       * }
-       * message GetMessageRequest {
-       * message SubMessage {
-       * string subfield = 1;
-       * }
-       * string message_id = 1; // Mapped to URL path.
-       * int64 revision = 2;    // Mapped to URL query parameter `revision`.
-       * SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
-       * }
-       * 
-       * This enables a HTTP JSON to RPC mapping as below:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `GET /v1/messages/123456?revision=2&sub.subfield=foo` |
-       * `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield:
-       * "foo"))`
-       * 
-       * Note that fields which are mapped to URL query parameters must have a
-       * primitive type or a repeated primitive type or a non-repeated message type.
-       * In the case of a repeated type, the parameter can be repeated in the URL
-       * as `...?param=A&param=B`. In the case of a message type, each field of the
-       * message is mapped to a separate parameter, such as
-       * `...?foo.a=A&foo.b=B&foo.c=C`.
-       * 
-       * For HTTP methods that allow a request body, the `body` field
-       * specifies the mapping. Consider a REST update method on the
-       * message resource collection:
-       * 
-       * service Messaging {
-       * rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
-       * option (google.api.http) = {
-       * patch: "/v1/messages/{message_id}"
-       * body: "message"
-       * };
-       * }
-       * }
-       * message UpdateMessageRequest {
-       * string message_id = 1; // mapped to the URL
-       * Message message = 2;   // mapped to the body
-       * }
-       * 
-       * The following HTTP JSON to RPC mapping is enabled, where the
-       * representation of the JSON in the request body is determined by
-       * protos JSON encoding:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
-       * "123456" message { text: "Hi!" })`
-       * 
-       * The special name `*` can be used in the body mapping to define that
-       * every field not bound by the path template should be mapped to the
-       * request body.  This enables the following alternative definition of
-       * the update method:
-       * 
-       * service Messaging {
-       * rpc UpdateMessage(Message) returns (Message) {
-       * option (google.api.http) = {
-       * patch: "/v1/messages/{message_id}"
-       * body: "*"
-       * };
-       * }
-       * }
-       * message Message {
-       * string message_id = 1;
-       * string text = 2;
-       * }
-       * 
-       * 
-       * The following HTTP JSON to RPC mapping is enabled:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
-       * "123456" text: "Hi!")`
-       * 
-       * Note that when using `*` in the body mapping, it is not possible to
-       * have HTTP parameters, as all fields not bound by the path end in
-       * the body. This makes this option more rarely used in practice when
-       * defining REST APIs. The common usage of `*` is in custom methods
-       * which don't use the URL at all for transferring data.
-       * 
-       * It is possible to define multiple HTTP methods for one RPC by using
-       * the `additional_bindings` option. Example:
-       * 
-       * service Messaging {
-       * rpc GetMessage(GetMessageRequest) returns (Message) {
-       * option (google.api.http) = {
-       * get: "/v1/messages/{message_id}"
-       * additional_bindings {
-       * get: "/v1/users/{user_id}/messages/{message_id}"
-       * }
-       * };
-       * }
-       * }
-       * message GetMessageRequest {
-       * string message_id = 1;
-       * string user_id = 2;
-       * }
-       * 
-       * This enables the following two alternative HTTP JSON to RPC mappings:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
-       * `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id:
-       * "123456")`
-       * 
-       * ## Rules for HTTP mapping
-       * 
-       * 1. Leaf request fields (recursive expansion nested messages in the request
-       * message) are classified into three categories:
-       * - Fields referred by the path template. They are passed via the URL path.
-       * - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They are passed via the HTTP
-       * request body.
-       * - All other fields are passed via the URL query parameters, and the
-       * parameter name is the field path in the request message. A repeated
-       * field can be represented as multiple query parameters under the same
-       * name.
-       * 2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields
-       * are passed via URL path and HTTP request body.
-       * 3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP request body, all
-       * fields are passed via URL path and URL query parameters.
-       * 
-       * ### Path template syntax
-       * 
-       * Template = "/" Segments [ Verb ] ;
-       * Segments = Segment { "/" Segment } ;
-       * Segment  = "*" | "**" | LITERAL | Variable ;
-       * Variable = "{" FieldPath [ "=" Segments ] "}" ;
-       * FieldPath = IDENT { "." IDENT } ;
-       * Verb     = ":" LITERAL ;
-       * 
-       * The syntax `*` matches a single URL path segment. The syntax `**` matches
-       * zero or more URL path segments, which must be the last part of the URL path
-       * except the `Verb`.
-       * 
-       * The syntax `Variable` matches part of the URL path as specified by its
-       * template. A variable template must not contain other variables. If a variable
-       * matches a single path segment, its template may be omitted, e.g. `{var}`
-       * is equivalent to `{var=*}`.
-       * 
-       * The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
-       * contains any reserved character, such characters should be percent-encoded
-       * before the matching.
-       * 
-       * If a variable contains exactly one path segment, such as `"{var}"` or
-       * `"{var=*}"`, when such a variable is expanded into a URL path on the client
-       * side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The
-       * server side does the reverse decoding. Such variables show up in the
-       * [Discovery
-       * Document](https://developers.google.com/discovery/v1/reference/apis) as
-       * `{var}`.
-       * 
-       * If a variable contains multiple path segments, such as `"{var=foo/*}"`
-       * or `"{var=**}"`, when such a variable is expanded into a URL path on the
-       * client side, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded.
-       * The server side does the reverse decoding, except "%2F" and "%2f" are left
-       * unchanged. Such variables show up in the
-       * [Discovery
-       * Document](https://developers.google.com/discovery/v1/reference/apis) as
-       * `{+var}`.
-       *

-       * that supports both gRPC APIs and REST APIs. Many systems, including [Google
-       * APIs](https://github.com/googleapis/googleapis),
-       * [Cloud Endpoints](https://cloud.google.com/endpoints), [gRPC
-       * Gateway](https://github.com/grpc-ecosystem/grpc-gateway),
-       * and [Envoy](https://github.com/envoyproxy/envoy) proxy support this feature
-       * and use it for large scale production services.
-       * 
-       * `HttpRule` defines the schema of the gRPC/REST mapping. The mapping specifies
-       * how different portions of the gRPC request message are mapped to the URL
-       * path, URL query parameters, and HTTP request body. It also controls how the
-       * gRPC response message is mapped to the HTTP response body. `HttpRule` is
-       * typically specified as an `google.api.http` annotation on the gRPC method.
-       * 
-       * Each mapping specifies a URL path template and an HTTP method. The path
-       * template may refer to one or more fields in the gRPC request message, as long
-       * as each field is a non-repeated field with a primitive (non-message) type.
-       * The path template controls how fields of the request message are mapped to
-       * the URL path.
-       * 
-       * Example:
-       * 
-       * service Messaging {
-       * rpc GetMessage(GetMessageRequest) returns (Message) {
-       * option (google.api.http) = {
-       * get: "/v1/{name=messages/*}"
-       * };
-       * }
-       * }
-       * message GetMessageRequest {
-       * string name = 1; // Mapped to URL path.
-       * }
-       * message Message {
-       * string text = 1; // The resource content.
-       * }
-       * 
-       * This enables an HTTP REST to gRPC mapping as below:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `GET /v1/messages/123456`  | `GetMessage(name: "messages/123456")`
-       * 
-       * Any fields in the request message which are not bound by the path template
-       * automatically become HTTP query parameters if there is no HTTP request body.
-       * For example:
-       * 
-       * service Messaging {
-       * rpc GetMessage(GetMessageRequest) returns (Message) {
-       * option (google.api.http) = {
-       * get:"/v1/messages/{message_id}"
-       * };
-       * }
-       * }
-       * message GetMessageRequest {
-       * message SubMessage {
-       * string subfield = 1;
-       * }
-       * string message_id = 1; // Mapped to URL path.
-       * int64 revision = 2;    // Mapped to URL query parameter `revision`.
-       * SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
-       * }
-       * 
-       * This enables a HTTP JSON to RPC mapping as below:

-       * HTTP | gRPC
-       * -----|-----
-       * `GET /v1/messages/123456?revision=2&sub.subfield=foo` |
-       * `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield:
-       * "foo"))`
-       * 
-       * Note that fields which are mapped to URL query parameters must have a
-       * primitive type or a repeated primitive type or a non-repeated message type.
-       * In the case of a repeated type, the parameter can be repeated in the URL
-       * as `...?param=A&param=B`. In the case of a message type, each field of the
-       * message is mapped to a separate parameter, such as
-       * `...?foo.a=A&foo.b=B&foo.c=C`.
-       * 
-       * For HTTP methods that allow a request body, the `body` field
-       * specifies the mapping. Consider a REST update method on the
-       * message resource collection:
-       * 
-       * service Messaging {
-       * rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
-       * option (google.api.http) = {
-       * patch: "/v1/messages/{message_id}"
-       * body: "message"
-       * };
-       * }
-       * }
-       * message UpdateMessageRequest {
-       * string message_id = 1; // mapped to the URL
-       * Message message = 2;   // mapped to the body
-       * }
-       * 
-       * The following HTTP JSON to RPC mapping is enabled, where the
-       * representation of the JSON in the request body is determined by
-       * protos JSON encoding:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
-       * "123456" message { text: "Hi!" })`
-       * 
-       * The special name `*` can be used in the body mapping to define that
-       * every field not bound by the path template should be mapped to the
-       * request body.  This enables the following alternative definition of
-       * the update method:
-       * 
-       * service Messaging {
-       * rpc UpdateMessage(Message) returns (Message) {
-       * option (google.api.http) = {
-       * patch: "/v1/messages/{message_id}"
-       * body: "*"
-       * };
-       * }
-       * }
-       * message Message {
-       * string message_id = 1;
-       * string text = 2;
-       * }
-       * 
-       * 
-       * The following HTTP JSON to RPC mapping is enabled:

-       * 
-       * Note that when using `*` in the body mapping, it is not possible to
-       * have HTTP parameters, as all fields not bound by the path end in
-       * the body. This makes this option more rarely used in practice when
-       * defining REST APIs. The common usage of `*` is in custom methods
-       * which don't use the URL at all for transferring data.
-       * 
-       * It is possible to define multiple HTTP methods for one RPC by using
-       * the `additional_bindings` option. Example:
-       * 
-       * service Messaging {

-       * string user_id = 2;
-       * }
-       * 
-       * This enables the following two alternative HTTP JSON to RPC mappings:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
-       * `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id:
-       * "123456")`
-       * 
-       * ## Rules for HTTP mapping
-       * 
-       * 1. Leaf request fields (recursive expansion nested messages in the request
-       * message) are classified into three categories:
-       * - Fields referred by the path template. They are passed via the URL path.
-       * - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They are passed via the HTTP
-       * request body.
-       * - All other fields are passed via the URL query parameters, and the
-       * parameter name is the field path in the request message. A repeated
-       * field can be represented as multiple query parameters under the same
-       * name.
-       * 2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields
-       * are passed via URL path and HTTP request body.
-       * 3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP request body, all
-       * fields are passed via URL path and URL query parameters.
-       * 
-       * ### Path template syntax
-       * 
-       * Template = "/" Segments [ Verb ] ;
-       * Segments = Segment { "/" Segment } ;
-       * Segment  = "*" | "**" | LITERAL | Variable ;
-       * Variable = "{" FieldPath [ "=" Segments ] "}" ;
-       * FieldPath = IDENT { "." IDENT } ;
-       * Verb     = ":" LITERAL ;
-       * 
-       * The syntax `*` matches a single URL path segment. The syntax `**` matches
-       * zero or more URL path segments, which must be the last part of the URL path
-       * except the `Verb`.
-       * 
-       * The syntax `Variable` matches part of the URL path as specified by its
-       * template. A variable template must not contain other variables. If a variable
-       * matches a single path segment, its template may be omitted, e.g. `{var}`
-       * is equivalent to `{var=*}`.
-       * 
-       * The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
-       * contains any reserved character, such characters should be percent-encoded
-       * before the matching.
-       * 
-       * If a variable contains exactly one path segment, such as `"{var}"` or
-       * `"{var=*}"`, when such a variable is expanded into a URL path on the client
-       * side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The
-       * server side does the reverse decoding. Such variables show up in the
-       * [Discovery
-       * Document](https://developers.google.com/discovery/v1/reference/apis) as
-       * `{var}`.
-       * 
-       * If a variable contains multiple path segments, such as `"{var=foo/*}"`
-       * or `"{var=**}"`, when such a variable is expanded into a URL path on the
-       * client side, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded.
-       * The server side does the reverse decoding, except "%2F" and "%2f" are left
-       * unchanged. Such variables show up in the
-       * [Discovery
-       * Document](https://developers.google.com/discovery/v1/reference/apis) as
-       * `{+var}`.
-       * 
-       * ## Using gRPC API Service Configuration
-       * 
-       * gRPC API Service Configuration (service config) is a configuration language
-       * for configuring a gRPC service to become a user-facing product. The
-       * service config is simply the YAML representation of the `google.api.Service`
-       * proto message.
-       * 
-       * As an alternative to annotating your proto file, you can configure gRPC
-       * transcoding in your service config YAML files. You do this by specifying a
-       * `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same
-       * effect as the proto annotation. This can be particularly useful if you
-       * have a proto that is reused in multiple services. Note that any transcoding
-       * specified in the service config will override any matching transcoding
-       * configuration in the proto.
-       * 
-       * Example:
-       * 
-       * http:
-       * rules:
-       * # Selects a gRPC method and applies HttpRule to it.
-       * - selector: example.v1.Messaging.GetMessage
-       * get: /v1/messages/{message_id}/{sub.subfield}
-       * 
-       * ## Special notes
-       * 
-       * When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
-       * proto to JSON conversion must follow the [proto3
-       * specification](https://developers.google.com/protocol-buffers/docs/proto3#json).
-       * 
-       * While the single segment variable follows the semantics of
-       * [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
-       * Expansion, the multi segment variable **does not** follow RFC 6570 Section
-       * 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
-       * does not expand special characters like `?` and `#`, which would lead
-       * to invalid URLs. As the result, gRPC Transcoding uses a custom encoding
-       * for multi segment variables.
-       * 
-       * The path variables **must not** refer to any repeated or mapped field,
-       * because client libraries are not capable of handling such variable expansion.
-       * 
-       * The path variables **must not** capture the leading "/" character. The reason
-       * is that the most common use case "{var}" does not capture the leading "/"
-       * character. For consistency, all path variables must share the same behavior.
-       * 
-       * Repeated message fields must not be mapped to URL query parameters, because
-       * no client library can support such complicated mapping.
-       * 
-       * If an API needs to use a JSON array for request or response body, it can map
-       * the request or response body to a repeated field. However, some gRPC
-       * Transcoding implementations may not support this feature.

-       * # gRPC Transcoding
-       * 
-       * gRPC Transcoding is a feature for mapping between a gRPC method and one or
-       * more HTTP REST endpoints. It allows developers to build a single API service
-       * that supports both gRPC APIs and REST APIs. Many systems, including [Google
-       * APIs](https://github.com/googleapis/googleapis),
-       * [Cloud Endpoints](https://cloud.google.com/endpoints), [gRPC
-       * Gateway](https://github.com/grpc-ecosystem/grpc-gateway),
-       * and [Envoy](https://github.com/envoyproxy/envoy) proxy support this feature
-       * and use it for large scale production services.
-       * 
-       * `HttpRule` defines the schema of the gRPC/REST mapping. The mapping specifies
-       * how different portions of the gRPC request message are mapped to the URL
-       * path, URL query parameters, and HTTP request body. It also controls how the
-       * gRPC response message is mapped to the HTTP response body. `HttpRule` is
-       * typically specified as an `google.api.http` annotation on the gRPC method.
-       * 
-       * Each mapping specifies a URL path template and an HTTP method. The path
-       * template may refer to one or more fields in the gRPC request message, as long
-       * as each field is a non-repeated field with a primitive (non-message) type.
-       * The path template controls how fields of the request message are mapped to
-       * the URL path.
-       * 
-       * Example:
-       * 
-       * service Messaging {
-       * rpc GetMessage(GetMessageRequest) returns (Message) {
-       * option (google.api.http) = {
-       * get: "/v1/{name=messages/*}"
-       * };
-       * }
-       * }
-       * message GetMessageRequest {
-       * string name = 1; // Mapped to URL path.
-       * }
-       * message Message {
-       * string text = 1; // The resource content.
-       * }
-       * 
-       * This enables an HTTP REST to gRPC mapping as below:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `GET /v1/messages/123456`  | `GetMessage(name: "messages/123456")`
-       * 
-       * Any fields in the request message which are not bound by the path template
-       * automatically become HTTP query parameters if there is no HTTP request body.
-       * For example:
-       * 
-       * service Messaging {
-       * rpc GetMessage(GetMessageRequest) returns (Message) {
-       * option (google.api.http) = {
-       * get:"/v1/messages/{message_id}"
-       * };
-       * }
-       * }
-       * message GetMessageRequest {
-       * message SubMessage {
-       * string subfield = 1;
-       * }
-       * string message_id = 1; // Mapped to URL path.
-       * int64 revision = 2;    // Mapped to URL query parameter `revision`.
-       * SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
-       * }
-       * 
-       * This enables a HTTP JSON to RPC mapping as below:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `GET /v1/messages/123456?revision=2&sub.subfield=foo` |
-       * `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield:
-       * "foo"))`
-       * 
-       * Note that fields which are mapped to URL query parameters must have a
-       * primitive type or a repeated primitive type or a non-repeated message type.

-       * For HTTP methods that allow a request body, the `body` field
-       * specifies the mapping. Consider a REST update method on the

-       * Document](https://developers.google.com/discovery/v1/reference/apis) as
-       * `{+var}`.
-       * 
-       * ## Using gRPC API Service Configuration
-       * 
-       * gRPC API Service Configuration (service config) is a configuration language
-       * for configuring a gRPC service to become a user-facing product. The
-       * service config is simply the YAML representation of the `google.api.Service`
-       * proto message.
-       * 
-       * As an alternative to annotating your proto file, you can configure gRPC
-       * transcoding in your service config YAML files. You do this by specifying a
-       * `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same
-       * effect as the proto annotation. This can be particularly useful if you
-       * have a proto that is reused in multiple services. Note that any transcoding
-       * specified in the service config will override any matching transcoding
-       * configuration in the proto.
-       * 
-       * Example:
-       * 
-       * http:
-       * rules:
-       * # Selects a gRPC method and applies HttpRule to it.
-       * - selector: example.v1.Messaging.GetMessage
-       * get: /v1/messages/{message_id}/{sub.subfield}
-       * 
-       * ## Special notes
-       * 
-       * When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
-       * proto to JSON conversion must follow the [proto3
-       * specification](https://developers.google.com/protocol-buffers/docs/proto3#json).
-       * 
-       * While the single segment variable follows the semantics of
-       * [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
-       * Expansion, the multi segment variable **does not** follow RFC 6570 Section
-       * 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
-       * does not expand special characters like `?` and `#`, which would lead
-       * to invalid URLs. As the result, gRPC Transcoding uses a custom encoding
-       * for multi segment variables.
-       * 
-       * The path variables **must not** refer to any repeated or mapped field,
-       * because client libraries are not capable of handling such variable expansion.
-       * 
-       * The path variables **must not** capture the leading "/" character. The reason
-       * is that the most common use case "{var}" does not capture the leading "/"
-       * character. For consistency, all path variables must share the same behavior.
-       * 
-       * Repeated message fields must not be mapped to URL query parameters, because
-       * no client library can support such complicated mapping.
-       * 
-       * If an API needs to use a JSON array for request or response body, it can map
-       * the request or response body to a repeated field. However, some gRPC
-       * Transcoding implementations may not support this feature.

-       * 
-       * `HttpRule` defines the schema of the gRPC/REST mapping. The mapping specifies

-       * typically specified as an `google.api.http` annotation on the gRPC method.
-       * 
-       * Each mapping specifies a URL path template and an HTTP method. The path
-       * template may refer to one or more fields in the gRPC request message, as long
-       * as each field is a non-repeated field with a primitive (non-message) type.
-       * The path template controls how fields of the request message are mapped to
-       * the URL path.
-       * 
-       * Example:
-       * 
-       * service Messaging {
-       * rpc GetMessage(GetMessageRequest) returns (Message) {
-       * option (google.api.http) = {
-       * get: "/v1/{name=messages/*}"
-       * };
-       * }
-       * }
-       * message GetMessageRequest {
-       * string name = 1; // Mapped to URL path.
-       * }
-       * message Message {
-       * string text = 1; // The resource content.
-       * }
-       * 
-       * This enables an HTTP REST to gRPC mapping as below:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `GET /v1/messages/123456`  | `GetMessage(name: "messages/123456")`
-       * 
-       * Any fields in the request message which are not bound by the path template
-       * automatically become HTTP query parameters if there is no HTTP request body.
-       * For example:
-       * 
-       * service Messaging {
-       * rpc GetMessage(GetMessageRequest) returns (Message) {
-       * option (google.api.http) = {
-       * get:"/v1/messages/{message_id}"
-       * };
-       * }
-       * }
-       * message GetMessageRequest {
-       * message SubMessage {
-       * string subfield = 1;
-       * }
-       * string message_id = 1; // Mapped to URL path.
-       * int64 revision = 2;    // Mapped to URL query parameter `revision`.
-       * SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
-       * }
-       * 
-       * This enables a HTTP JSON to RPC mapping as below:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `GET /v1/messages/123456?revision=2&sub.subfield=foo` |
-       * `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield:
-       * "foo"))`
-       * 
-       * Note that fields which are mapped to URL query parameters must have a
-       * primitive type or a repeated primitive type or a non-repeated message type.
-       * In the case of a repeated type, the parameter can be repeated in the URL
-       * as `...?param=A&param=B`. In the case of a message type, each field of the
-       * message is mapped to a separate parameter, such as
-       * `...?foo.a=A&foo.b=B&foo.c=C`.
-       * 
-       * For HTTP methods that allow a request body, the `body` field
-       * specifies the mapping. Consider a REST update method on the
-       * message resource collection:
-       * 
-       * service Messaging {
-       * rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
-       * option (google.api.http) = {
-       * patch: "/v1/messages/{message_id}"
-       * body: "message"
-       * };
-       * }
-       * }
-       * message UpdateMessageRequest {
-       * string message_id = 1; // mapped to the URL
-       * Message message = 2;   // mapped to the body
-       * }
-       * 
-       * The following HTTP JSON to RPC mapping is enabled, where the
-       * representation of the JSON in the request body is determined by
-       * protos JSON encoding:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
-       * "123456" message { text: "Hi!" })`
-       * 
-       * The special name `*` can be used in the body mapping to define that
-       * every field not bound by the path template should be mapped to the
-       * request body.  This enables the following alternative definition of
-       * the update method:
-       * 
-       * service Messaging {
-       * rpc UpdateMessage(Message) returns (Message) {
-       * option (google.api.http) = {
-       * patch: "/v1/messages/{message_id}"
-       * body: "*"
-       * };
-       * }
-       * }
-       * message Message {
-       * string message_id = 1;
-       * string text = 2;
-       * }
-       * 
-       * 
-       * The following HTTP JSON to RPC mapping is enabled:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
-       * "123456" text: "Hi!")`
-       * 
-       * Note that when using `*` in the body mapping, it is not possible to
-       * have HTTP parameters, as all fields not bound by the path end in
-       * the body. This makes this option more rarely used in practice when
-       * defining REST APIs. The common usage of `*` is in custom methods
-       * which don't use the URL at all for transferring data.
-       * 
-       * It is possible to define multiple HTTP methods for one RPC by using
-       * the `additional_bindings` option. Example:
-       * 
-       * service Messaging {
-       * rpc GetMessage(GetMessageRequest) returns (Message) {
-       * option (google.api.http) = {
-       * get: "/v1/messages/{message_id}"
-       * additional_bindings {
-       * get: "/v1/users/{user_id}/messages/{message_id}"
-       * }
-       * };
-       * }
-       * }
-       * message GetMessageRequest {
-       * string message_id = 1;
-       * string user_id = 2;
-       * }
-       * 
-       * This enables the following two alternative HTTP JSON to RPC mappings:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
-       * `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id:
-       * "123456")`
-       * 
-       * ## Rules for HTTP mapping
-       * 
-       * 1. Leaf request fields (recursive expansion nested messages in the request
-       * message) are classified into three categories:
-       * - Fields referred by the path template. They are passed via the URL path.
-       * - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They are passed via the HTTP
-       * request body.
-       * - All other fields are passed via the URL query parameters, and the
-       * parameter name is the field path in the request message. A repeated
-       * field can be represented as multiple query parameters under the same
-       * name.
-       * 2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields
-       * are passed via URL path and HTTP request body.
-       * 3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP request body, all
-       * fields are passed via URL path and URL query parameters.
-       * 
-       * ### Path template syntax
-       * 
-       * Template = "/" Segments [ Verb ] ;
-       * Segments = Segment { "/" Segment } ;
-       * Segment  = "*" | "**" | LITERAL | Variable ;
-       * Variable = "{" FieldPath [ "=" Segments ] "}" ;
-       * FieldPath = IDENT { "." IDENT } ;
-       * Verb     = ":" LITERAL ;
-       * 
-       * The syntax `*` matches a single URL path segment. The syntax `**` matches
-       * zero or more URL path segments, which must be the last part of the URL path
-       * except the `Verb`.
-       * 
-       * The syntax `Variable` matches part of the URL path as specified by its
-       * template. A variable template must not contain other variables. If a variable
-       * matches a single path segment, its template may be omitted, e.g. `{var}`
-       * is equivalent to `{var=*}`.
-       * 
-       * The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
-       * contains any reserved character, such characters should be percent-encoded
-       * before the matching.
-       * 
-       * If a variable contains exactly one path segment, such as `"{var}"` or
-       * `"{var=*}"`, when such a variable is expanded into a URL path on the client
-       * side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The
-       * server side does the reverse decoding. Such variables show up in the
-       * [Discovery
-       * Document](https://developers.google.com/discovery/v1/reference/apis) as
-       * `{var}`.
-       * 
-       * If a variable contains multiple path segments, such as `"{var=foo/*}"`
-       * or `"{var=**}"`, when such a variable is expanded into a URL path on the
-       * client side, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded.
-       * The server side does the reverse decoding, except "%2F" and "%2f" are left
-       * unchanged. Such variables show up in the
-       * [Discovery
-       * Document](https://developers.google.com/discovery/v1/reference/apis) as
-       * `{+var}`.
-       * 
-       * ## Using gRPC API Service Configuration
-       * 
-       * gRPC API Service Configuration (service config) is a configuration language
-       * for configuring a gRPC service to become a user-facing product. The
-       * service config is simply the YAML representation of the `google.api.Service`
-       * proto message.
-       * 
-       * As an alternative to annotating your proto file, you can configure gRPC
-       * transcoding in your service config YAML files. You do this by specifying a
-       * `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same
-       * effect as the proto annotation. This can be particularly useful if you
-       * have a proto that is reused in multiple services. Note that any transcoding
-       * specified in the service config will override any matching transcoding
-       * configuration in the proto.
-       * 
-       * Example:
-       * 
-       * http:
-       * rules:
-       * # Selects a gRPC method and applies HttpRule to it.
-       * - selector: example.v1.Messaging.GetMessage
-       * get: /v1/messages/{message_id}/{sub.subfield}
-       * 
-       * ## Special notes
-       * 
-       * When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
-       * proto to JSON conversion must follow the [proto3
-       * specification](https://developers.google.com/protocol-buffers/docs/proto3#json).
-       * 
-       * While the single segment variable follows the semantics of
-       * [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
-       * Expansion, the multi segment variable **does not** follow RFC 6570 Section
-       * 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
-       * does not expand special characters like `?` and `#`, which would lead
-       * to invalid URLs. As the result, gRPC Transcoding uses a custom encoding
-       * for multi segment variables.
-       * 
-       * The path variables **must not** refer to any repeated or mapped field,
-       * because client libraries are not capable of handling such variable expansion.
-       * 
-       * The path variables **must not** capture the leading "/" character. The reason
-       * is that the most common use case "{var}" does not capture the leading "/"
-       * character. For consistency, all path variables must share the same behavior.
-       * 
-       * Repeated message fields must not be mapped to URL query parameters, because
-       * no client library can support such complicated mapping.
-       * 
-       * If an API needs to use a JSON array for request or response body, it can map
-       * the request or response body to a repeated field. However, some gRPC
-       * Transcoding implementations may not support this feature.

-       * The path template controls how fields of the request message are mapped to
-       * the URL path.
-       * 
-       * Example:
-       * 
-       * service Messaging {
-       * rpc GetMessage(GetMessageRequest) returns (Message) {
-       * option (google.api.http) = {
-       * get: "/v1/{name=messages/*}"
-       * };
-       * }
-       * }
-       * message GetMessageRequest {
-       * string name = 1; // Mapped to URL path.
-       * }
-       * message Message {
-       * string text = 1; // The resource content.
-       * }
-       * 
-       * This enables an HTTP REST to gRPC mapping as below:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `GET /v1/messages/123456`  | `GetMessage(name: "messages/123456")`
-       * 
-       * Any fields in the request message which are not bound by the path template
-       * automatically become HTTP query parameters if there is no HTTP request body.
-       * For example:
-       * 
-       * service Messaging {
-       * rpc GetMessage(GetMessageRequest) returns (Message) {
-       * option (google.api.http) = {
-       * get:"/v1/messages/{message_id}"
-       * };
-       * }
-       * }
-       * message GetMessageRequest {
-       * message SubMessage {
-       * string subfield = 1;
-       * }
-       * string message_id = 1; // Mapped to URL path.
-       * int64 revision = 2;    // Mapped to URL query parameter `revision`.
-       * SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
-       * }
-       * 
-       * This enables a HTTP JSON to RPC mapping as below:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `GET /v1/messages/123456?revision=2&sub.subfield=foo` |
-       * `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield:
-       * "foo"))`
-       * 
-       * Note that fields which are mapped to URL query parameters must have a
-       * primitive type or a repeated primitive type or a non-repeated message type.
-       * In the case of a repeated type, the parameter can be repeated in the URL
-       * as `...?param=A&param=B`. In the case of a message type, each field of the
-       * message is mapped to a separate parameter, such as
-       * `...?foo.a=A&foo.b=B&foo.c=C`.
-       * 
-       * For HTTP methods that allow a request body, the `body` field
-       * specifies the mapping. Consider a REST update method on the
-       * message resource collection:
-       * 
-       * service Messaging {
-       * rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
-       * option (google.api.http) = {
-       * patch: "/v1/messages/{message_id}"
-       * body: "message"
-       * };
-       * }
-       * }
-       * message UpdateMessageRequest {
-       * string message_id = 1; // mapped to the URL
-       * Message message = 2;   // mapped to the body
-       * }
-       * 
-       * The following HTTP JSON to RPC mapping is enabled, where the
-       * representation of the JSON in the request body is determined by
-       * protos JSON encoding:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
-       * "123456" message { text: "Hi!" })`
-       * 
-       * The special name `*` can be used in the body mapping to define that
-       * every field not bound by the path template should be mapped to the
-       * request body.  This enables the following alternative definition of
-       * the update method:
-       * 
-       * service Messaging {
-       * rpc UpdateMessage(Message) returns (Message) {
-       * option (google.api.http) = {
-       * patch: "/v1/messages/{message_id}"
-       * body: "*"
-       * };
-       * }
-       * }
-       * message Message {
-       * string message_id = 1;
-       * string text = 2;
-       * }
-       * 
-       * 
-       * The following HTTP JSON to RPC mapping is enabled:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
-       * "123456" text: "Hi!")`
-       * 
-       * Note that when using `*` in the body mapping, it is not possible to
-       * have HTTP parameters, as all fields not bound by the path end in
-       * the body. This makes this option more rarely used in practice when
-       * defining REST APIs. The common usage of `*` is in custom methods
-       * which don't use the URL at all for transferring data.
-       * 
-       * It is possible to define multiple HTTP methods for one RPC by using
-       * the `additional_bindings` option. Example:
-       * 
-       * service Messaging {
-       * rpc GetMessage(GetMessageRequest) returns (Message) {
-       * option (google.api.http) = {
-       * get: "/v1/messages/{message_id}"
-       * additional_bindings {
-       * get: "/v1/users/{user_id}/messages/{message_id}"
-       * }
-       * };
-       * }
-       * }
-       * message GetMessageRequest {
-       * string message_id = 1;
-       * string user_id = 2;
-       * }
-       * 
-       * This enables the following two alternative HTTP JSON to RPC mappings:
-       * 
-       * HTTP | gRPC
-       * -----|-----
-       * `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
-       * `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id:
-       * "123456")`
-       * 
-       * ## Rules for HTTP mapping
-       * 
-       * 1. Leaf request fields (recursive expansion nested messages in the request
-       * message) are classified into three categories:
-       * - Fields referred by the path template. They are passed via the URL path.
-       * - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They are passed via the HTTP
-       * request body.
-       * - All other fields are passed via the URL query parameters, and the
-       * parameter name is the field path in the request message. A repeated
-       * field can be represented as multiple query parameters under the same
-       * name.
-       * 2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields
-       * are passed via URL path and HTTP request body.
-       * 3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP request body, all
-       * fields are passed via URL path and URL query parameters.
-       * 
-       * ### Path template syntax
-       * 
-       * Template = "/" Segments [ Verb ] ;
-       * Segments = Segment { "/" Segment } ;
-       * Segment  = "*" | "**" | LITERAL | Variable ;
-       * Variable = "{" FieldPath [ "=" Segments ] "}" ;
-       * FieldPath = IDENT { "." IDENT } ;
-       * Verb     = ":" LITERAL ;
-       * 
-       * The syntax `*` matches a single URL path segment. The syntax `**` matches
-       * zero or more URL path segments, which must be the last part of the URL path
-       * except the `Verb`.
-       * 
-       * The syntax `Variable` matches part of the URL path as specified by its
-       * template. A variable template must not contain other variables. If a variable
-       * matches a single path segment, its template may be omitted, e.g. `{var}`
-       * is equivalent to `{var=*}`.
-       * 
-       * The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
-       * contains any reserved character, such characters should be percent-encoded
-       * before the matching.
-       * 
-       * If a variable contains exactly one path segment, such as `"{var}"` or
-       * `"{var=*}"`, when such a variable is expanded into a URL path on the client
-       * side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The
-       * server side does the reverse decoding. Such variables show up in the
-       * [Discovery
-       * Document](https://developers.google.com/discovery/v1/reference/apis) as
-       * `{var}`.
-       * 
-       * If a variable contains multiple path segments, such as `"{var=foo/*}"`
-       * or `"{var=**}"`, when such a variable is expanded into a URL path on the
-       * client side, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded.
-       * The server side does the reverse decoding, except "%2F" and "%2f" are left
-       * unchanged. Such variables show up in the
-       * [Discovery
-       * Document](https://developers.google.com/discovery/v1/reference/apis) as
-       * `{+var}`.
-       * 
-       * ## Using gRPC API Service Configuration
-       * 
-       * gRPC API Service Configuration (service config) is a configuration language
-       * for configuring a gRPC service to become a user-facing product. The
-       * service config is simply the YAML representation of the `google.api.Service`
-       * proto message.
-       * 
-       * As an alternative to annotating your proto file, you can configure gRPC
-       * transcoding in your service config YAML files. You do this by specifying a
-       * `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same
-       * effect as the proto annotation. This can be particularly useful if you
-       * have a proto that is reused in multiple services. Note that any transcoding
-       * specified in the service config will override any matching transcoding
-       * configuration in the proto.
-       * 
-       * Example:
-       * 
-       * http:
-       * rules:
-       * # Selects a gRPC method and applies HttpRule to it.
-       * - selector: example.v1.Messaging.GetMessage
-       * get: /v1/messages/{message_id}/{sub.subfield}
-       * 
-       * ## Special notes
-       * 
-       * When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
-       * proto to JSON conversion must follow the [proto3
-       * specification](https://developers.google.com/protocol-buffers/docs/proto3#json).
-       * 
-       * While the single segment variable follows the semantics of
-       * [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
-       * Expansion, the multi segment variable **does not** follow RFC 6570 Section
-       * 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
-       * does not expand special characters like `?` and `#`, which would lead
-       * to invalid URLs. As the result, gRPC Transcoding uses a custom encoding
-       * for multi segment variables.
-       * 
-       * The path variables **must not** refer to any repeated or mapped field,
-       * because client libraries are not capable of handling such variable expansion.
-       * 
-       * The path variables **must not** capture the leading "/" character. The reason
-       * is that the most common use case "{var}" does not capture the leading "/"
-       * character. For consistency, all path variables must share the same behavior.
-       * 
-       * Repeated message fields must not be mapped to URL query parameters, because
-       * no client library can support such complicated mapping.
-       * 
-       * If an API needs to use a JSON array for request or response body, it can map
-       * the request or response body to a repeated field. However, some gRPC
-       * Transcoding implementations may not support this feature.

+/**
+ * # gRPC Transcoding
+ * 
+ * gRPC Transcoding is a feature for mapping between a gRPC method and one or
+ * more HTTP REST endpoints. It allows developers to build a single API service
+ * that supports both gRPC APIs and REST APIs. Many systems, including [Google
+ * APIs](https://github.com/googleapis/googleapis),
+ * [Cloud Endpoints](https://cloud.google.com/endpoints), [gRPC
+ * Gateway](https://github.com/grpc-ecosystem/grpc-gateway),
+ * and [Envoy](https://github.com/envoyproxy/envoy) proxy support this feature
+ * and use it for large scale production services.
+ * 
+ * `HttpRule` defines the schema of the gRPC/REST mapping. The mapping specifies
+ * how different portions of the gRPC request message are mapped to the URL
+ * path, URL query parameters, and HTTP request body. It also controls how the
+ * gRPC response message is mapped to the HTTP response body. `HttpRule` is
+ * typically specified as an `google.api.http` annotation on the gRPC method.
+ * 
+ * Each mapping specifies a URL path template and an HTTP method. The path
+ * template may refer to one or more fields in the gRPC request message, as long
+ * as each field is a non-repeated field with a primitive (non-message) type.
+ * The path template controls how fields of the request message are mapped to
+ * the URL path.
+ * 
+ * Example:
+ * 
+ * service Messaging {
+ * rpc GetMessage(GetMessageRequest) returns (Message) {
+ * option (google.api.http) = {
+ * get: "/v1/{name=messages/*}"
+ * };
+ * }
+ * }
+ * message GetMessageRequest {
+ * string name = 1; // Mapped to URL path.
+ * }
+ * message Message {
+ * string text = 1; // The resource content.
+ * }
+ * 
+ * This enables an HTTP REST to gRPC mapping as below:
+ * 
+ * HTTP | gRPC
+ * -----|-----
+ * `GET /v1/messages/123456`  | `GetMessage(name: "messages/123456")`
+ * 
+ * Any fields in the request message which are not bound by the path template
+ * automatically become HTTP query parameters if there is no HTTP request body.
+ * For example:
+ * 
+ * service Messaging {
+ * rpc GetMessage(GetMessageRequest) returns (Message) {
+ * option (google.api.http) = {
+ * get:"/v1/messages/{message_id}"
+ * };
+ * }
+ * }
+ * message GetMessageRequest {
+ * message SubMessage {
+ * string subfield = 1;
+ * }
+ * string message_id = 1; // Mapped to URL path.
+ * int64 revision = 2;    // Mapped to URL query parameter `revision`.
+ * SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
+ * }
+ * 
+ * This enables a HTTP JSON to RPC mapping as below:
+ * 
+ * HTTP | gRPC
+ * -----|-----
+ * `GET /v1/messages/123456?revision=2&sub.subfield=foo` |
+ * `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield:
+ * "foo"))`
+ * 
+ * Note that fields which are mapped to URL query parameters must have a
+ * primitive type or a repeated primitive type or a non-repeated message type.
+ * In the case of a repeated type, the parameter can be repeated in the URL
+ * as `...?param=A&param=B`. In the case of a message type, each field of the
+ * message is mapped to a separate parameter, such as
+ * `...?foo.a=A&foo.b=B&foo.c=C`.
+ * 
+ * For HTTP methods that allow a request body, the `body` field
+ * specifies the mapping. Consider a REST update method on the
+ * message resource collection:
+ * 
+ * service Messaging {
+ * rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
+ * option (google.api.http) = {
+ * patch: "/v1/messages/{message_id}"
+ * body: "message"
+ * };
+ * }
+ * }
+ * message UpdateMessageRequest {
+ * string message_id = 1; // mapped to the URL
+ * Message message = 2;   // mapped to the body
+ * }
+ * 
+ * The following HTTP JSON to RPC mapping is enabled, where the
+ * representation of the JSON in the request body is determined by
+ * protos JSON encoding:
+ * 
+ * HTTP | gRPC
+ * -----|-----
+ * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+ * "123456" message { text: "Hi!" })`
+ * 
+ * The special name `*` can be used in the body mapping to define that
+ * every field not bound by the path template should be mapped to the
+ * request body.  This enables the following alternative definition of
+ * the update method:
+ * 
+ * service Messaging {
+ * rpc UpdateMessage(Message) returns (Message) {
+ * option (google.api.http) = {
+ * patch: "/v1/messages/{message_id}"
+ * body: "*"
+ * };
+ * }
+ * }
+ * message Message {
+ * string message_id = 1;
+ * string text = 2;
+ * }
+ * 
+ * 
+ * The following HTTP JSON to RPC mapping is enabled:
+ * 
+ * HTTP | gRPC
+ * -----|-----
+ * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+ * "123456" text: "Hi!")`
+ * 
+ * Note that when using `*` in the body mapping, it is not possible to
+ * have HTTP parameters, as all fields not bound by the path end in
+ * the body. This makes this option more rarely used in practice when
+ * defining REST APIs. The common usage of `*` is in custom methods
+ * which don't use the URL at all for transferring data.
+ * 
+ * It is possible to define multiple HTTP methods for one RPC by using
+ * the `additional_bindings` option. Example:
+ * 
+ * service Messaging {
+ * rpc GetMessage(GetMessageRequest) returns (Message) {
+ * option (google.api.http) = {
+ * get: "/v1/messages/{message_id}"
+ * additional_bindings {
+ * get: "/v1/users/{user_id}/messages/{message_id}"
+ * }
+ * };
+ * }
+ * }
+ * message GetMessageRequest {
+ * string message_id = 1;
+ * string user_id = 2;
+ * }
+ * 
+ * This enables the following two alternative HTTP JSON to RPC mappings:
+ * 
+ * HTTP | gRPC
+ * -----|-----
+ * `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
+ * `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id:
+ * "123456")`
+ * 
+ * ## Rules for HTTP mapping
+ * 
+ * 1. Leaf request fields (recursive expansion nested messages in the request
+ * message) are classified into three categories:
+ * - Fields referred by the path template. They are passed via the URL path.
+ * - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They are passed via the HTTP
+ * request body.
+ * - All other fields are passed via the URL query parameters, and the
+ * parameter name is the field path in the request message. A repeated
+ * field can be represented as multiple query parameters under the same
+ * name.
+ * 2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields
+ * are passed via URL path and HTTP request body.
+ * 3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP request body, all
+ * fields are passed via URL path and URL query parameters.
+ * 
+ * ### Path template syntax
+ * 
+ * Template = "/" Segments [ Verb ] ;
+ * Segments = Segment { "/" Segment } ;
+ * Segment  = "*" | "**" | LITERAL | Variable ;
+ * Variable = "{" FieldPath [ "=" Segments ] "}" ;
+ * FieldPath = IDENT { "." IDENT } ;
+ * Verb     = ":" LITERAL ;
+ * 
+ * The syntax `*` matches a single URL path segment. The syntax `**` matches
+ * zero or more URL path segments, which must be the last part of the URL path
+ * except the `Verb`.
+ * 
+ * The syntax `Variable` matches part of the URL path as specified by its
+ * template. A variable template must not contain other variables. If a variable
+ * matches a single path segment, its template may be omitted, e.g. `{var}`
+ * is equivalent to `{var=*}`.
+ * 
+ * The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
+ * contains any reserved character, such characters should be percent-encoded
+ * before the matching.
+ * 
+ * If a variable contains exactly one path segment, such as `"{var}"` or
+ * `"{var=*}"`, when such a variable is expanded into a URL path on the client
+ * side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The
+ * server side does the reverse decoding. Such variables show up in the
+ * [Discovery
+ * Document](https://developers.google.com/discovery/v1/reference/apis) as
+ * `{var}`.
+ * 
+ * If a variable contains multiple path segments, such as `"{var=foo/*}"`
+ * or `"{var=**}"`, when such a variable is expanded into a URL path on the
+ * client side, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded.
+ * The server side does the reverse decoding, except "%2F" and "%2f" are left
+ * unchanged. Such variables show up in the
+ * [Discovery
+ * Document](https://developers.google.com/discovery/v1/reference/apis) as
+ * `{+var}`.
+ * 
+ * ## Using gRPC API Service Configuration
+ * 
+ * gRPC API Service Configuration (service config) is a configuration language
+ * for configuring a gRPC service to become a user-facing product. The
+ * service config is simply the YAML representation of the `google.api.Service`
+ * proto message.
+ * 
+ * As an alternative to annotating your proto file, you can configure gRPC
+ * transcoding in your service config YAML files. You do this by specifying a
+ * `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same
+ * effect as the proto annotation. This can be particularly useful if you
+ * have a proto that is reused in multiple services. Note that any transcoding
+ * specified in the service config will override any matching transcoding
+ * configuration in the proto.
+ * 
+ * Example:
+ * 
+ * http:
+ * rules:
+ * # Selects a gRPC method and applies HttpRule to it.
+ * - selector: example.v1.Messaging.GetMessage
+ * get: /v1/messages/{message_id}/{sub.subfield}
+ * 
+ * ## Special notes
+ * 
+ * When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
+ * proto to JSON conversion must follow the [proto3
+ * specification](https://developers.google.com/protocol-buffers/docs/proto3#json).
+ * 
+ * While the single segment variable follows the semantics of
+ * [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
+ * Expansion, the multi segment variable **does not** follow RFC 6570 Section
+ * 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
+ * does not expand special characters like `?` and `#`, which would lead
+ * to invalid URLs. As the result, gRPC Transcoding uses a custom encoding
+ * for multi segment variables.
+ * 
+ * The path variables **must not** refer to any repeated or mapped field,
+ * because client libraries are not capable of handling such variable expansion.
+ * 
+ * The path variables **must not** capture the leading "/" character. The reason
+ * is that the most common use case "{var}" does not capture the leading "/"
+ * character. For consistency, all path variables must share the same behavior.
+ * 
+ * Repeated message fields must not be mapped to URL query parameters, because
+ * no client library can support such complicated mapping.
+ * 
+ * If an API needs to use a JSON array for request or response body, it can map
+ * the request or response body to a repeated field. However, some gRPC
+ * Transcoding implementations may not support this feature.

+/**
+ * # gRPC Transcoding
+ * 
+ * gRPC Transcoding is a feature for mapping between a gRPC method and one or
+ * more HTTP REST endpoints. It allows developers to build a single API service
+ * that supports both gRPC APIs and REST APIs. Many systems, including [Google
+ * APIs](https://github.com/googleapis/googleapis),
+ * [Cloud Endpoints](https://cloud.google.com/endpoints), [gRPC
+ * Gateway](https://github.com/grpc-ecosystem/grpc-gateway),
+ * and [Envoy](https://github.com/envoyproxy/envoy) proxy support this feature
+ * and use it for large scale production services.
+ * 
+ * `HttpRule` defines the schema of the gRPC/REST mapping. The mapping specifies
+ * how different portions of the gRPC request message are mapped to the URL
+ * path, URL query parameters, and HTTP request body. It also controls how the
+ * gRPC response message is mapped to the HTTP response body. `HttpRule` is
+ * typically specified as an `google.api.http` annotation on the gRPC method.
+ * 
+ * Each mapping specifies a URL path template and an HTTP method. The path
+ * template may refer to one or more fields in the gRPC request message, as long
+ * as each field is a non-repeated field with a primitive (non-message) type.
+ * The path template controls how fields of the request message are mapped to
+ * the URL path.
+ * 
+ * Example:
+ * 
+ * service Messaging {
+ * rpc GetMessage(GetMessageRequest) returns (Message) {
+ * option (google.api.http) = {
+ * get: "/v1/{name=messages/*}"
+ * };
+ * }
+ * }
+ * message GetMessageRequest {
+ * string name = 1; // Mapped to URL path.
+ * }
+ * message Message {
+ * string text = 1; // The resource content.
+ * }
+ * 
+ * This enables an HTTP REST to gRPC mapping as below:
+ * 
+ * HTTP | gRPC
+ * -----|-----
+ * `GET /v1/messages/123456`  | `GetMessage(name: "messages/123456")`
+ * 
+ * Any fields in the request message which are not bound by the path template
+ * automatically become HTTP query parameters if there is no HTTP request body.
+ * For example:
+ * 
+ * service Messaging {
+ * rpc GetMessage(GetMessageRequest) returns (Message) {
+ * option (google.api.http) = {
+ * get:"/v1/messages/{message_id}"
+ * };
+ * }
+ * }
+ * message GetMessageRequest {
+ * message SubMessage {
+ * string subfield = 1;
+ * }
+ * string message_id = 1; // Mapped to URL path.
+ * int64 revision = 2;    // Mapped to URL query parameter `revision`.
+ * SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
+ * }
+ * 
+ * This enables a HTTP JSON to RPC mapping as below:
+ * 
+ * HTTP | gRPC
+ * -----|-----
+ * `GET /v1/messages/123456?revision=2&sub.subfield=foo` |
+ * `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield:
+ * "foo"))`
+ * 
+ * Note that fields which are mapped to URL query parameters must have a
+ * primitive type or a repeated primitive type or a non-repeated message type.
+ * In the case of a repeated type, the parameter can be repeated in the URL
+ * as `...?param=A&param=B`. In the case of a message type, each field of the
+ * message is mapped to a separate parameter, such as
+ * `...?foo.a=A&foo.b=B&foo.c=C`.
+ * 
+ * For HTTP methods that allow a request body, the `body` field
+ * specifies the mapping. Consider a REST update method on the
+ * message resource collection:
+ * 
+ * service Messaging {
+ * rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
+ * option (google.api.http) = {
+ * patch: "/v1/messages/{message_id}"
+ * body: "message"
+ * };
+ * }
+ * }
+ * message UpdateMessageRequest {
+ * string message_id = 1; // mapped to the URL
+ * Message message = 2;   // mapped to the body
+ * }
+ * 
+ * The following HTTP JSON to RPC mapping is enabled, where the
+ * representation of the JSON in the request body is determined by
+ * protos JSON encoding:
+ * 
+ * HTTP | gRPC
+ * -----|-----
+ * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+ * "123456" message { text: "Hi!" })`
+ * 
+ * The special name `*` can be used in the body mapping to define that
+ * every field not bound by the path template should be mapped to the
+ * request body.  This enables the following alternative definition of
+ * the update method:
+ * 
+ * service Messaging {
+ * rpc UpdateMessage(Message) returns (Message) {
+ * option (google.api.http) = {
+ * patch: "/v1/messages/{message_id}"
+ * body: "*"
+ * };
+ * }
+ * }
+ * message Message {
+ * string message_id = 1;
+ * string text = 2;
+ * }
+ * 
+ * 
+ * The following HTTP JSON to RPC mapping is enabled:
+ * 
+ * HTTP | gRPC
+ * -----|-----
+ * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+ * "123456" text: "Hi!")`
+ * 
+ * Note that when using `*` in the body mapping, it is not possible to
+ * have HTTP parameters, as all fields not bound by the path end in
+ * the body. This makes this option more rarely used in practice when
+ * defining REST APIs. The common usage of `*` is in custom methods
+ * which don't use the URL at all for transferring data.
+ * 
+ * It is possible to define multiple HTTP methods for one RPC by using
+ * the `additional_bindings` option. Example:
+ * 
+ * service Messaging {
+ * rpc GetMessage(GetMessageRequest) returns (Message) {
+ * option (google.api.http) = {
+ * get: "/v1/messages/{message_id}"
+ * additional_bindings {
+ * get: "/v1/users/{user_id}/messages/{message_id}"
+ * }
+ * };
+ * }
+ * }
+ * message GetMessageRequest {
+ * string message_id = 1;
+ * string user_id = 2;
+ * }
+ * 
+ * This enables the following two alternative HTTP JSON to RPC mappings:
+ * 
+ * HTTP | gRPC
+ * -----|-----
+ * `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
+ * `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id:
+ * "123456")`
+ * 
+ * ## Rules for HTTP mapping
+ * 
+ * 1. Leaf request fields (recursive expansion nested messages in the request
+ * message) are classified into three categories:
+ * - Fields referred by the path template. They are passed via the URL path.
+ * - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They are passed via the HTTP
+ * request body.
+ * - All other fields are passed via the URL query parameters, and the
+ * parameter name is the field path in the request message. A repeated
+ * field can be represented as multiple query parameters under the same
+ * name.
+ * 2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields
+ * are passed via URL path and HTTP request body.
+ * 3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP request body, all
+ * fields are passed via URL path and URL query parameters.
+ * 
+ * ### Path template syntax
+ * 
+ * Template = "/" Segments [ Verb ] ;
+ * Segments = Segment { "/" Segment } ;
+ * Segment  = "*" | "**" | LITERAL | Variable ;
+ * Variable = "{" FieldPath [ "=" Segments ] "}" ;
+ * FieldPath = IDENT { "." IDENT } ;
+ * Verb     = ":" LITERAL ;
+ * 
+ * The syntax `*` matches a single URL path segment. The syntax `**` matches
+ * zero or more URL path segments, which must be the last part of the URL path
+ * except the `Verb`.
+ * 
+ * The syntax `Variable` matches part of the URL path as specified by its
+ * template. A variable template must not contain other variables. If a variable
+ * matches a single path segment, its template may be omitted, e.g. `{var}`
+ * is equivalent to `{var=*}`.
+ * 
+ * The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
+ * contains any reserved character, such characters should be percent-encoded
+ * before the matching.
+ * 
+ * If a variable contains exactly one path segment, such as `"{var}"` or
+ * `"{var=*}"`, when such a variable is expanded into a URL path on the client
+ * side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The
+ * server side does the reverse decoding. Such variables show up in the
+ * [Discovery
+ * Document](https://developers.google.com/discovery/v1/reference/apis) as
+ * `{var}`.
+ * 
+ * If a variable contains multiple path segments, such as `"{var=foo/*}"`
+ * or `"{var=**}"`, when such a variable is expanded into a URL path on the
+ * client side, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded.
+ * The server side does the reverse decoding, except "%2F" and "%2f" are left
+ * unchanged. Such variables show up in the
+ * [Discovery
+ * Document](https://developers.google.com/discovery/v1/reference/apis) as
+ * `{+var}`.
+ * 
+ * ## Using gRPC API Service Configuration
+ * 
+ * gRPC API Service Configuration (service config) is a configuration language
+ * for configuring a gRPC service to become a user-facing product. The
+ * service config is simply the YAML representation of the `google.api.Service`
+ * proto message.
+ * 
+ * As an alternative to annotating your proto file, you can configure gRPC
+ * transcoding in your service config YAML files. You do this by specifying a
+ * `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same
+ * effect as the proto annotation. This can be particularly useful if you
+ * have a proto that is reused in multiple services. Note that any transcoding
+ * specified in the service config will override any matching transcoding
+ * configuration in the proto.
+ * 
+ * Example:
+ * 
+ * http:
+ * rules:
+ * # Selects a gRPC method and applies HttpRule to it.
+ * - selector: example.v1.Messaging.GetMessage
+ * get: /v1/messages/{message_id}/{sub.subfield}
+ * 
+ * ## Special notes
+ * 
+ * When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
+ * proto to JSON conversion must follow the [proto3
+ * specification](https://developers.google.com/protocol-buffers/docs/proto3#json).
+ * 
+ * While the single segment variable follows the semantics of
+ * [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
+ * Expansion, the multi segment variable **does not** follow RFC 6570 Section
+ * 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
+ * does not expand special characters like `?` and `#`, which would lead
+ * to invalid URLs. As the result, gRPC Transcoding uses a custom encoding
+ * for multi segment variables.
+ * 
+ * The path variables **must not** refer to any repeated or mapped field,
+ * because client libraries are not capable of handling such variable expansion.
+ * 
+ * The path variables **must not** capture the leading "/" character. The reason
+ * is that the most common use case "{var}" does not capture the leading "/"
+ * character. For consistency, all path variables must share the same behavior.
+ * 
+ * Repeated message fields must not be mapped to URL query parameters, because
+ * no client library can support such complicated mapping.
+ * 
+ * If an API needs to use a JSON array for request or response body, it can map
+ * the request or response body to a repeated field. However, some gRPC
+ * Transcoding implementations may not support this feature.

+## Generating TypeScript types
+
+The `proto-loader-gen-types` script distributed with this package can be used to generate TypeScript type information for the objects loaded at runtime. More information about how to use it can be found in [the *@grpc/proto-loader TypeScript Type Generator CLI Tool* proposal document](https://github.com/grpc/proposal/blob/master/L70-node-proto-loader-type-generator.md). The arguments mostly match the `load` function's options; the full usage information is as follows:

 - If you are currently loading `.proto` files using `grpc.load`, that function is not available in this library. You should instead load your `.proto` files using `@grpc/proto-loader` and load the resulting package definition objects into `@grpc/grpc-js` using `grpc.loadPackageDefinition`.

However, [documentation is available for the `grpc` package](https://grpc.github.io/grpc/node/grpc.html), and the two packages contain mostly the same interface.

Subject: [PATCH 1216/1899] Channel#watchConnectivityState: handle infinite
 deadlines correctly

Per https://grpc.github.io/grpc/node/grpc.html#~Deadline:
"If it is a finite number, it is treated as a number of milliseconds
since the Unix Epoch. If it is Infinity, the deadline will never be
reached. If it is -Infinity, the deadline has already passed."

Subject: [PATCH 1254/1899] Fix ClientOptions types

Remove index signature from ChannelOptions to fix intersection error
described in #1558 which causes issues on using ClientOptions direct
fields with TypeScript.

Removing of index signature required few minor changes:
 - adding few constant types that were used throughout the app
 - using `as const` assertion in xds-client
 - using not-so-great type cast in channelOptionsEqual

Alternative solution would be removing the index signature from
ChannelOptions explicitly in ClientOptions definition, which is not
trivial and probably calls for a generic type helper.

See: https://github.com/grpc/grpc-node/issues/1558
Fixes: #1558

 - The class `Call` is only exposed due to limitations of TypeScript. It should not be considered part of the public API.
 - In general, any API that is exposed by this library but is not exposed by the `grpc` library is likely an error and should not be considered part of the public API.
+- The `grpc.experimental` namespace contains APIs that have not stabilized. Any API in that namespace may break in any minor version update.

Subject: [PATCH 1325/1899] Refactor loadFileDescriptorSetFile to not catch
 JSON decoding errors

This change ensures that errors are not hidden when
loadFileDescriptorSet fails to decode JSON. Instead, only JSON parsing
errors are hidden.

-/**
- * # gRPC Transcoding
- * 
- * gRPC Transcoding is a feature for mapping between a gRPC method and one or
- * more HTTP REST endpoints. It allows developers to build a single API service
- * that supports both gRPC APIs and REST APIs. Many systems, including [Google
- * APIs](https://github.com/googleapis/googleapis),
- * [Cloud Endpoints](https://cloud.google.com/endpoints), [gRPC
- * Gateway](https://github.com/grpc-ecosystem/grpc-gateway),
- * and [Envoy](https://github.com/envoyproxy/envoy) proxy support this feature
- * and use it for large scale production services.
- * 
- * `HttpRule` defines the schema of the gRPC/REST mapping. The mapping specifies
- * how different portions of the gRPC request message are mapped to the URL
- * path, URL query parameters, and HTTP request body. It also controls how the
- * gRPC response message is mapped to the HTTP response body. `HttpRule` is
- * typically specified as an `google.api.http` annotation on the gRPC method.
- * 
- * Each mapping specifies a URL path template and an HTTP method. The path
- * template may refer to one or more fields in the gRPC request message, as long
- * as each field is a non-repeated field with a primitive (non-message) type.
- * The path template controls how fields of the request message are mapped to
- * the URL path.
- * 
- * Example:
- * 
- * service Messaging {
- * rpc GetMessage(GetMessageRequest) returns (Message) {
- * option (google.api.http) = {
- * get: "/v1/{name=messages/*}"
- * };
- * }
- * }
- * message GetMessageRequest {
- * string name = 1; // Mapped to URL path.
- * }
- * message Message {
- * string text = 1; // The resource content.
- * }
- * 
- * This enables an HTTP REST to gRPC mapping as below:
- * 
- * HTTP | gRPC
- * -----|-----
- * `GET /v1/messages/123456`  | `GetMessage(name: "messages/123456")`
- * 
- * Any fields in the request message which are not bound by the path template
- * automatically become HTTP query parameters if there is no HTTP request body.
- * For example:
- * 
- * service Messaging {
- * rpc GetMessage(GetMessageRequest) returns (Message) {
- * option (google.api.http) = {
- * get:"/v1/messages/{message_id}"
- * };
- * }
- * }
- * message GetMessageRequest {
- * message SubMessage {
- * string subfield = 1;
- * }
- * string message_id = 1; // Mapped to URL path.
- * int64 revision = 2;    // Mapped to URL query parameter `revision`.
- * SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
- * }
- * 
- * This enables a HTTP JSON to RPC mapping as below:
- * 
- * HTTP | gRPC
- * -----|-----
- * `GET /v1/messages/123456?revision=2&sub.subfield=foo` |
- * `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield:
- * "foo"))`
- * 
- * Note that fields which are mapped to URL query parameters must have a
- * primitive type or a repeated primitive type or a non-repeated message type.
- * In the case of a repeated type, the parameter can be repeated in the URL
- * as `...?param=A&param=B`. In the case of a message type, each field of the
- * message is mapped to a separate parameter, such as
- * `...?foo.a=A&foo.b=B&foo.c=C`.
- * 
- * For HTTP methods that allow a request body, the `body` field
- * specifies the mapping. Consider a REST update method on the
- * message resource collection:
- * 
- * service Messaging {
- * rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
- * option (google.api.http) = {
- * patch: "/v1/messages/{message_id}"
- * body: "message"
- * };
- * }
- * }
- * message UpdateMessageRequest {
- * string message_id = 1; // mapped to the URL
- * Message message = 2;   // mapped to the body
- * }
- * 
- * The following HTTP JSON to RPC mapping is enabled, where the
- * representation of the JSON in the request body is determined by
- * protos JSON encoding:
- * 
- * HTTP | gRPC
- * -----|-----
- * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
- * "123456" message { text: "Hi!" })`
- * 
- * The special name `*` can be used in the body mapping to define that
- * every field not bound by the path template should be mapped to the
- * request body.  This enables the following alternative definition of
- * the update method:
- * 
- * service Messaging {
- * rpc UpdateMessage(Message) returns (Message) {
- * option (google.api.http) = {
- * patch: "/v1/messages/{message_id}"
- * body: "*"
- * };
- * }
- * }
- * message Message {
- * string message_id = 1;
- * string text = 2;
- * }
- * 
- * 
- * The following HTTP JSON to RPC mapping is enabled:
- * 
- * HTTP | gRPC
- * -----|-----
- * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
- * "123456" text: "Hi!")`
- * 
- * Note that when using `*` in the body mapping, it is not possible to
- * have HTTP parameters, as all fields not bound by the path end in
- * the body. This makes this option more rarely used in practice when
- * defining REST APIs. The common usage of `*` is in custom methods
- * which don't use the URL at all for transferring data.
- * 
- * It is possible to define multiple HTTP methods for one RPC by using
- * the `additional_bindings` option. Example:
- * 
- * service Messaging {
- * rpc GetMessage(GetMessageRequest) returns (Message) {
- * option (google.api.http) = {
- * get: "/v1/messages/{message_id}"
- * additional_bindings {
- * get: "/v1/users/{user_id}/messages/{message_id}"
- * }
- * };
- * }
- * }
- * message GetMessageRequest {
- * string message_id = 1;
- * string user_id = 2;
- * }
- * 
- * This enables the following two alternative HTTP JSON to RPC mappings:
- * 
- * HTTP | gRPC
- * -----|-----
- * `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
- * `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id:
- * "123456")`
- * 
- * ## Rules for HTTP mapping
- * 
- * 1. Leaf request fields (recursive expansion nested messages in the request
- * message) are classified into three categories:
- * - Fields referred by the path template. They are passed via the URL path.
- * - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They are passed via the HTTP
- * request body.
- * - All other fields are passed via the URL query parameters, and the
- * parameter name is the field path in the request message. A repeated
- * field can be represented as multiple query parameters under the same
- * name.
- * 2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields
- * are passed via URL path and HTTP request body.
- * 3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP request body, all
- * fields are passed via URL path and URL query parameters.
- * 
- * ### Path template syntax
- * 
- * Template = "/" Segments [ Verb ] ;
- * Segments = Segment { "/" Segment } ;
- * Segment  = "*" | "**" | LITERAL | Variable ;
- * Variable = "{" FieldPath [ "=" Segments ] "}" ;
- * FieldPath = IDENT { "." IDENT } ;
- * Verb     = ":" LITERAL ;
- * 
- * The syntax `*` matches a single URL path segment. The syntax `**` matches
- * zero or more URL path segments, which must be the last part of the URL path
- * except the `Verb`.
- * 
- * The syntax `Variable` matches part of the URL path as specified by its
- * template. A variable template must not contain other variables. If a variable
- * matches a single path segment, its template may be omitted, e.g. `{var}`
- * is equivalent to `{var=*}`.
- * 
- * The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
- * contains any reserved character, such characters should be percent-encoded
- * before the matching.
- * 
- * If a variable contains exactly one path segment, such as `"{var}"` or
- * `"{var=*}"`, when such a variable is expanded into a URL path on the client
- * side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The
- * server side does the reverse decoding. Such variables show up in the
- * [Discovery
- * Document](https://developers.google.com/discovery/v1/reference/apis) as
- * `{var}`.
- * 
- * If a variable contains multiple path segments, such as `"{var=foo/*}"`
- * or `"{var=**}"`, when such a variable is expanded into a URL path on the
- * client side, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded.
- * The server side does the reverse decoding, except "%2F" and "%2f" are left
- * unchanged. Such variables show up in the
- * [Discovery
- * Document](https://developers.google.com/discovery/v1/reference/apis) as
- * `{+var}`.
- * 
- * ## Using gRPC API Service Configuration
- * 
- * gRPC API Service Configuration (service config) is a configuration language
- * for configuring a gRPC service to become a user-facing product. The
- * service config is simply the YAML representation of the `google.api.Service`
- * proto message.
- * 
- * As an alternative to annotating your proto file, you can configure gRPC
- * transcoding in your service config YAML files. You do this by specifying a
- * `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same
- * effect as the proto annotation. This can be particularly useful if you
- * have a proto that is reused in multiple services. Note that any transcoding
- * specified in the service config will override any matching transcoding
- * configuration in the proto.
- * 
- * Example:
- * 
- * http:
- * rules:
- * # Selects a gRPC method and applies HttpRule to it.
- * - selector: example.v1.Messaging.GetMessage
- * get: /v1/messages/{message_id}/{sub.subfield}
- * 
- * ## Special notes
- * 
- * When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
- * proto to JSON conversion must follow the [proto3
- * specification](https://developers.google.com/protocol-buffers/docs/proto3#json).
- * 
- * While the single segment variable follows the semantics of
- * [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
- * Expansion, the multi segment variable **does not** follow RFC 6570 Section
- * 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
- * does not expand special characters like `?` and `#`, which would lead
- * to invalid URLs. As the result, gRPC Transcoding uses a custom encoding
- * for multi segment variables.
- * 
- * The path variables **must not** refer to any repeated or mapped field,
- * because client libraries are not capable of handling such variable expansion.
- * 
- * The path variables **must not** capture the leading "/" character. The reason
- * is that the most common use case "{var}" does not capture the leading "/"
- * character. For consistency, all path variables must share the same behavior.
- * 
- * Repeated message fields must not be mapped to URL query parameters, because
- * no client library can support such complicated mapping.
- * 
- * If an API needs to use a JSON array for request or response body, it can map
- * the request or response body to a repeated field. However, some gRPC
- * Transcoding implementations may not support this feature.

- * The syntax `*` matches a single URL path segment. The syntax `**` matches
- * zero or more URL path segments, which must be the last part of the URL path
- * except the `Verb`.
- * 
- * The syntax `Variable` matches part of the URL path as specified by its
- * template. A variable template must not contain other variables. If a variable
- * matches a single path segment, its template may be omitted, e.g. `{var}`
- * is equivalent to `{var=*}`.
- * 
- * The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
- * contains any reserved character, such characters should be percent-encoded
- * before the matching.
- * 
- * If a variable contains exactly one path segment, such as `"{var}"` or
- * `"{var=*}"`, when such a variable is expanded into a URL path on the client
- * side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The
- * server side does the reverse decoding. Such variables show up in the
- * [Discovery
- * Document](https://developers.google.com/discovery/v1/reference/apis) as
- * `{var}`.
- * 
- * If a variable contains multiple path segments, such as `"{var=foo/*}"`
- * or `"{var=**}"`, when such a variable is expanded into a URL path on the
- * client side, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded.
- * The server side does the reverse decoding, except "%2F" and "%2f" are left
- * unchanged. Such variables show up in the
- * [Discovery
- * Document](https://developers.google.com/discovery/v1/reference/apis) as
- * `{+var}`.
- * 
- * ## Using gRPC API Service Configuration
- * 
- * gRPC API Service Configuration (service config) is a configuration language
- * for configuring a gRPC service to become a user-facing product. The
- * service config is simply the YAML representation of the `google.api.Service`
- * proto message.
- * 
- * As an alternative to annotating your proto file, you can configure gRPC
- * transcoding in your service config YAML files. You do this by specifying a
- * `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same
- * effect as the proto annotation. This can be particularly useful if you
- * have a proto that is reused in multiple services. Note that any transcoding
- * specified in the service config will override any matching transcoding
- * configuration in the proto.
- * 
- * Example:
- * 
- * http:
- * rules:
- * # Selects a gRPC method and applies HttpRule to it.
- * - selector: example.v1.Messaging.GetMessage
- * get: /v1/messages/{message_id}/{sub.subfield}
- * 
- * ## Special notes
- * 
- * When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
- * proto to JSON conversion must follow the [proto3
- * specification](https://developers.google.com/protocol-buffers/docs/proto3#json).
- * 
- * While the single segment variable follows the semantics of
- * [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
- * Expansion, the multi segment variable **does not** follow RFC 6570 Section
- * 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
- * does not expand special characters like `?` and `#`, which would lead
- * to invalid URLs. As the result, gRPC Transcoding uses a custom encoding
- * for multi segment variables.
- * 
- * The path variables **must not** refer to any repeated or mapped field,
- * because client libraries are not capable of handling such variable expansion.
- * 
- * The path variables **must not** capture the leading "/" character. The reason
- * is that the most common use case "{var}" does not capture the leading "/"
- * character. For consistency, all path variables must share the same behavior.
- * 
- * Repeated message fields must not be mapped to URL query parameters, because
- * no client library can support such complicated mapping.
- * 
- * If an API needs to use a JSON array for request or response body, it can map
- * the request or response body to a repeated field. However, some gRPC
- * Transcoding implementations may not support this feature.

+#
+# To overcome the above limitations, we use the https://github.com/multiarch/qemu-user-static
+# docker image to provide a new enough version of qemu-user-static and register it with
+# the desired binfmt_misc flags. The most important flag we need is "F" (set by "--persistent yes"),
+# which allows the qemu-aarch64-static binary to be loaded eagerly at the time of registration with binfmt_misc.
+# That way, we can emulate aarch64 binaries running inside docker containers transparently, without needing the emulator
+# binary to be accessible from the docker image we're emulating.
+# Note that on newer distributions (such as glinux), simply "apt install qemu-user-static" is sufficient
+# to install qemu-user-static with the right flags.

+# Troubleshooting grpc-js
+
+This guide is for troubleshooting the `grpc-js` library for Node.js
+
+## Enabling extra logging and tracing
+
+Extra logging can be very useful for diagnosing problems. `grpc-js` supporst
+the `GRPC_VERBOSITY` and `GRPC_TRACE` environment variables that can be used to increase the amount of information
+that gets printed to stderr.
+
+## GRPC_VERBOSITY
+
+`GRPC_VERBOSITY` is used to set the minimum level of log messages printed by gRPC (supported values are `DEBUG`, `INFO` and `ERROR`). If this environment variable is unset, only `ERROR` logs will be printed.
+
+## GRPC_TRACE
+
+`GRPC_TRACE` can be used to enable extra logging for some internal gRPC components. Enabling the right traces can be invaluable
+for diagnosing for what is going wrong when things aren't working as intended. Possible values for `GRPC_TRACE` are listed in [Environment Variables Overview](doc/environment_variables.md).
+Multiple traces can be enabled at once (use comma as separator).
+
+```
+# Enable debug logs for an application
+GRPC_VERBOSITY=debug ./helloworld_application_using_grpc
+```
+
+```
+# Print information about channel state changes
+GRPC_VERBOSITY=debug GRPC_TRACE=connectivity_state ./helloworld_application_using_grpc
+```
+
+```
+# Print info from 3 different tracers, including tracing logs with log level DEBUG
+GRPC_VERBOSITY=debug GRPC_TRACE=channel,subchannel,call_stream ./helloworld_application_using_grpc
+```
+
+Please note that the `GRPC_TRACE` environment variable has nothing to do with gRPC's "tracing" feature (= tracing RPCs in
+microservice environment to gain insight about how requests are processed by deployment), it is merely used to enable printing
+of extra logs.

+# grpc-js environment variables
+
+`@grpc/grpc-js` exposes some configuration as environment variables that
+can be set.
+
+*For the legacy `grpc` library, the environment variables are documented
+[in the main gRPC repository](https://github.com/grpc/grpc/blob/master/doc/environment_variables.md)*
+
+* grpc_proxy, https_proxy, http_proxy
+  The URI of the proxy to use for HTTP CONNECT support. These variables are
+  checked in order, and the first one that has a value is used.
+
+* no_grpc_proxy, no_proxy
+  A comma separated list of hostnames to connect to without using a proxy even
+  if a proxy is set. These variables are checked in order, and the first one
+  that has a value is used.
+
+* GRPC_SSL_CIPHER_SUITES
+  A colon separated list of cipher suites to use with OpenSSL
+  Defaults to the defaults for Node.js
+
+* GRPC_DEFAULT_SSL_ROOTS_FILE_PATH
+  PEM file to load SSL roots from
+
+* GRPC_NODE_TRACE, GRPC_TRACE
+  A comma separated list of tracers that provide additional insight into how
+  grpc-js is processing requests via debug logs. Available tracers include:
+  - `call_stream` - Traces client request internals
+  - `channel` - Traces channel events
+  - `connectivity_state` - Traces channel connectivity state changes
+  - `dns_resolver` - Traces DNS resolution
+  - `pick_first` - Traces the pick first load balancing policy
+  - `proxy` - Traces proxy operations
+  - `resolving_load_balancer` - Traces the resolving load balancer
+  - `round_robin` - Traces the round robin load balancing policy
+  - `server` - Traces high-level server events
+  - `server_call` - Traces server handling of individual requests
+  - `subchannel` - Traces subchannel connectivity state and errors
+  - `subchannel_refcount` - Traces subchannel refcount changes
+
+  The following tracers are added by the `@grpc/grpc-js-xds` library:
+  - `cds_balancer` - Traces the CDS load balancing policy
+  - `eds_balancer` - Traces the EDS load balancing policy
+  - `priority` - Traces the priority load balancing policy
+  - `weighted_target` - Traces the weighted target load balancing policy
+  - `xds_client` - Traces the xDS Client
+  - `xds_cluster_manager` - Traces the xDS cluster manager load balancing policy
+  - `xds_resolver` - Traces the xDS name resolver
+
+  'all' can additionally be used to turn all traces on.
+  Individual traces can be disabled by prefixing them with '-'.
+
+* GRPC_NODE_VERBOSITY, GRPC_VERBOSITY
+  Default gRPC logging verbosity - one of:
+  - DEBUG - log all gRPC messages
+  - INFO - log INFO and ERROR message
+  - ERROR - log only errors (default)
+  - NONE - won't log any

Subject: [PATCH 1452/1899] Avoid unused definition imports from proto-loader

Since proto files don't always contain all types of definition, it was
possible to get into a state where generated code contained unused
imports which caused TS errors. This change makes those imports
conditional on the existence of the corresponding definitions in the
proto file.

Subject: [PATCH 1458/1899] Prevent early return in proto-loader
 containsDefinition

f289c343b3393aad73795c0657415f4160bcdcb5 introduced a bug - the
recursive for-loop descended into the first elements nested array
and returned that value without iterating over the other members
of the array. This means that the code would only work correctly
when the protofile contained a definition whose name was alphabetically
first amongst its siblings.

This commit fixes the issue by moving the call to containsDefinition
into the if statement to allow iteration to continue if
containsDefinition returns false.

+/**
+ * # gRPC Transcoding
+ * 
+ * gRPC Transcoding is a feature for mapping between a gRPC method and one or
+ * more HTTP REST endpoints. It allows developers to build a single API service
+ * that supports both gRPC APIs and REST APIs. Many systems, including [Google
+ * APIs](https://github.com/googleapis/googleapis),
+ * [Cloud Endpoints](https://cloud.google.com/endpoints), [gRPC
+ * Gateway](https://github.com/grpc-ecosystem/grpc-gateway),
+ * and [Envoy](https://github.com/envoyproxy/envoy) proxy support this feature
+ * and use it for large scale production services.
+ * 
+ * `HttpRule` defines the schema of the gRPC/REST mapping. The mapping specifies
+ * how different portions of the gRPC request message are mapped to the URL
+ * path, URL query parameters, and HTTP request body. It also controls how the
+ * gRPC response message is mapped to the HTTP response body. `HttpRule` is
+ * typically specified as an `google.api.http` annotation on the gRPC method.
+ * 
+ * Each mapping specifies a URL path template and an HTTP method. The path
+ * template may refer to one or more fields in the gRPC request message, as long
+ * as each field is a non-repeated field with a primitive (non-message) type.
+ * The path template controls how fields of the request message are mapped to
+ * the URL path.
+ * 
+ * Example:
+ * 
+ * service Messaging {
+ * rpc GetMessage(GetMessageRequest) returns (Message) {
+ * option (google.api.http) = {
+ * get: "/v1/{name=messages/*}"
+ * };
+ * }
+ * }
+ * message GetMessageRequest {
+ * string name = 1; // Mapped to URL path.
+ * }
+ * message Message {
+ * string text = 1; // The resource content.
+ * }
+ * 
+ * This enables an HTTP REST to gRPC mapping as below:
+ * 
+ * HTTP | gRPC
+ * -----|-----
+ * `GET /v1/messages/123456`  | `GetMessage(name: "messages/123456")`
+ * 
+ * Any fields in the request message which are not bound by the path template
+ * automatically become HTTP query parameters if there is no HTTP request body.
+ * For example:
+ * 
+ * service Messaging {
+ * rpc GetMessage(GetMessageRequest) returns (Message) {
+ * option (google.api.http) = {
+ * get:"/v1/messages/{message_id}"
+ * };
+ * }
+ * }
+ * message GetMessageRequest {
+ * message SubMessage {
+ * string subfield = 1;
+ * }
+ * string message_id = 1; // Mapped to URL path.
+ * int64 revision = 2;    // Mapped to URL query parameter `revision`.
+ * SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
+ * }
+ * 
+ * This enables a HTTP JSON to RPC mapping as below:
+ * 
+ * HTTP | gRPC
+ * -----|-----
+ * `GET /v1/messages/123456?revision=2&sub.subfield=foo` |
+ * `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield:
+ * "foo"))`
+ * 
+ * Note that fields which are mapped to URL query parameters must have a
+ * primitive type or a repeated primitive type or a non-repeated message type.
+ * In the case of a repeated type, the parameter can be repeated in the URL
+ * as `...?param=A&param=B`. In the case of a message type, each field of the
+ * message is mapped to a separate parameter, such as
+ * `...?foo.a=A&foo.b=B&foo.c=C`.
+ * 
+ * For HTTP methods that allow a request body, the `body` field
+ * specifies the mapping. Consider a REST update method on the
+ * message resource collection:
+ * 
+ * service Messaging {
+ * rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
+ * option (google.api.http) = {
+ * patch: "/v1/messages/{message_id}"
+ * body: "message"
+ * };
+ * }
+ * }
+ * message UpdateMessageRequest {
+ * string message_id = 1; // mapped to the URL
+ * Message message = 2;   // mapped to the body
+ * }
+ * 
+ * The following HTTP JSON to RPC mapping is enabled, where the
+ * representation of the JSON in the request body is determined by
+ * protos JSON encoding:
+ * 
+ * HTTP | gRPC
+ * -----|-----
+ * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+ * "123456" message { text: "Hi!" })`
+ * 
+ * The special name `*` can be used in the body mapping to define that
+ * every field not bound by the path template should be mapped to the
+ * request body.  This enables the following alternative definition of
+ * the update method:
+ * 
+ * service Messaging {
+ * rpc UpdateMessage(Message) returns (Message) {
+ * option (google.api.http) = {
+ * patch: "/v1/messages/{message_id}"
+ * body: "*"
+ * };
+ * }
+ * }
+ * message Message {
+ * string message_id = 1;
+ * string text = 2;
+ * }
+ * 
+ * 
+ * The following HTTP JSON to RPC mapping is enabled:
+ * 
+ * HTTP | gRPC
+ * -----|-----
+ * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
+ * "123456" text: "Hi!")`
+ * 
+ * Note that when using `*` in the body mapping, it is not possible to
+ * have HTTP parameters, as all fields not bound by the path end in
+ * the body. This makes this option more rarely used in practice when
+ * defining REST APIs. The common usage of `*` is in custom methods
+ * which don't use the URL at all for transferring data.
+ * 
+ * It is possible to define multiple HTTP methods for one RPC by using
+ * the `additional_bindings` option. Example:
+ * 
+ * service Messaging {
+ * rpc GetMessage(GetMessageRequest) returns (Message) {
+ * option (google.api.http) = {
+ * get: "/v1/messages/{message_id}"
+ * additional_bindings {
+ * get: "/v1/users/{user_id}/messages/{message_id}"
+ * }
+ * };
+ * }
+ * }
+ * message GetMessageRequest {
+ * string message_id = 1;
+ * string user_id = 2;
+ * }
+ * 
+ * This enables the following two alternative HTTP JSON to RPC mappings:
+ * 
+ * HTTP | gRPC
+ * -----|-----
+ * `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
+ * `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id:
+ * "123456")`
+ * 
+ * ## Rules for HTTP mapping
+ * 
+ * 1. Leaf request fields (recursive expansion nested messages in the request
+ * message) are classified into three categories:
+ * - Fields referred by the path template. They are passed via the URL path.
+ * - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They are passed via the HTTP
+ * request body.
+ * - All other fields are passed via the URL query parameters, and the
+ * parameter name is the field path in the request message. A repeated
+ * field can be represented as multiple query parameters under the same
+ * name.
+ * 2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields
+ * are passed via URL path and HTTP request body.
+ * 3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP request body, all
+ * fields are passed via URL path and URL query parameters.
+ * 
+ * ### Path template syntax
+ * 
+ * Template = "/" Segments [ Verb ] ;
+ * Segments = Segment { "/" Segment } ;
+ * Segment  = "*" | "**" | LITERAL | Variable ;
+ * Variable = "{" FieldPath [ "=" Segments ] "}" ;
+ * FieldPath = IDENT { "." IDENT } ;
+ * Verb     = ":" LITERAL ;
+ * 
+ * The syntax `*` matches a single URL path segment. The syntax `**` matches
+ * zero or more URL path segments, which must be the last part of the URL path
+ * except the `Verb`.
+ * 
+ * The syntax `Variable` matches part of the URL path as specified by its
+ * template. A variable template must not contain other variables. If a variable
+ * matches a single path segment, its template may be omitted, e.g. `{var}`
+ * is equivalent to `{var=*}`.
+ * 
+ * The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
+ * contains any reserved character, such characters should be percent-encoded
+ * before the matching.
+ * 
+ * If a variable contains exactly one path segment, such as `"{var}"` or
+ * `"{var=*}"`, when such a variable is expanded into a URL path on the client
+ * side, all characters except `[-_.~0-9a-zA-Z]` are percent-encoded. The
+ * server side does the reverse decoding. Such variables show up in the
+ * [Discovery
+ * Document](https://developers.google.com/discovery/v1/reference/apis) as
+ * `{var}`.
+ * 
+ * If a variable contains multiple path segments, such as `"{var=foo/*}"`
+ * or `"{var=**}"`, when such a variable is expanded into a URL path on the
+ * client side, all characters except `[-_.~/0-9a-zA-Z]` are percent-encoded.
+ * The server side does the reverse decoding, except "%2F" and "%2f" are left
+ * unchanged. Such variables show up in the
+ * [Discovery
+ * Document](https://developers.google.com/discovery/v1/reference/apis) as
+ * `{+var}`.
+ * 
+ * ## Using gRPC API Service Configuration
+ * 
+ * gRPC API Service Configuration (service config) is a configuration language
+ * for configuring a gRPC service to become a user-facing product. The
+ * service config is simply the YAML representation of the `google.api.Service`
+ * proto message.
+ * 
+ * As an alternative to annotating your proto file, you can configure gRPC
+ * transcoding in your service config YAML files. You do this by specifying a
+ * `HttpRule` that maps the gRPC method to a REST endpoint, achieving the same
+ * effect as the proto annotation. This can be particularly useful if you
+ * have a proto that is reused in multiple services. Note that any transcoding
+ * specified in the service config will override any matching transcoding
+ * configuration in the proto.
+ * 
+ * Example:
+ * 
+ * http:
+ * rules:
+ * # Selects a gRPC method and applies HttpRule to it.
+ * - selector: example.v1.Messaging.GetMessage
+ * get: /v1/messages/{message_id}/{sub.subfield}
+ * 
+ * ## Special notes
+ * 
+ * When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
+ * proto to JSON conversion must follow the [proto3
+ * specification](https://developers.google.com/protocol-buffers/docs/proto3#json).
+ * 
+ * While the single segment variable follows the semantics of
+ * [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
+ * Expansion, the multi segment variable **does not** follow RFC 6570 Section
+ * 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
+ * does not expand special characters like `?` and `#`, which would lead
+ * to invalid URLs. As the result, gRPC Transcoding uses a custom encoding
+ * for multi segment variables.
+ * 
+ * The path variables **must not** refer to any repeated or mapped field,
+ * because client libraries are not capable of handling such variable expansion.
+ * 
+ * The path variables **must not** capture the leading "/" character. The reason
+ * is that the most common use case "{var}" does not capture the leading "/"
+ * character. For consistency, all path variables must share the same behavior.
+ * 
+ * Repeated message fields must not be mapped to URL query parameters, because
+ * no client library can support such complicated mapping.
+ * 
+ * If an API needs to use a JSON array for request or response body, it can map
+ * the request or response body to a repeated field. However, some gRPC
+ * Transcoding implementations may not support this feature.

+ * 
+ * ## Special notes
+ * 
+ * When gRPC Transcoding is used to map a gRPC to JSON REST endpoints, the
+ * proto to JSON conversion must follow the [proto3
+ * specification](https://developers.google.com/protocol-buffers/docs/proto3#json).
+ * 
+ * While the single segment variable follows the semantics of
+ * [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
+ * Expansion, the multi segment variable **does not** follow RFC 6570 Section
+ * 3.2.3 Reserved Expansion. The reason is that the Reserved Expansion
+ * does not expand special characters like `?` and `#`, which would lead
+ * to invalid URLs. As the result, gRPC Transcoding uses a custom encoding
+ * for multi segment variables.
+ * 
+ * The path variables **must not** refer to any repeated or mapped field,
+ * because client libraries are not capable of handling such variable expansion.
+ * 
+ * The path variables **must not** capture the leading "/" character. The reason
+ * is that the most common use case "{var}" does not capture the leading "/"
+ * character. For consistency, all path variables must share the same behavior.
+ * 
+ * Repeated message fields must not be mapped to URL query parameters, because
+ * no client library can support such complicated mapping.
+ * 
+ * If an API needs to use a JSON array for request or response body, it can map
+ * the request or response body to a repeated field. However, some gRPC
+ * Transcoding implementations may not support this feature.

Subject: [PATCH 1748/1899] xDS interop: enable pod log collection in the
 buildscripts

- Enables pod log collection in all PSM interop jobs implemented
  in https://github.com/grpc/grpc/pull/30594.
- Associate test suite runs with their own log file, so it's displayed
  on the "Target Log" tab
- Adds missing `--force_cleanup` to the lb test (reduces leaked
  resources)
- Fix run_test not returning correct exit status, causing false
  positives in some cases. See https://github.com/grpc/grpc/pull/30768

Subject: [PATCH 1785/1899] fix: perf issues in hot paths

1. no unused timers, wrap tracing calls to avoid stringifying
2. track graceful end of the call and avoid emitting 'cancelled' in such cases
3. remove validate calls in metadata on operations where it's not needed
4. refactor server session stream handlers into separate channelz enabled/disabled handlers
5. refactor message request logic - reduce amount of microtasks generated
6. improve sendStatus a little when there is no metadata involved
