Rust API schema manipulation utilities

This directory contains a set of Rust crates to manipulate and transform the API specification's schema.json file. The primary feature is conversion of schema.json to an OpenAPI schema for Elasticsearch Serverless.

Workspace members

• clients_schema: a Rust implementation of the Elasticsearch specification schema metamodel.
• clients_schema_to_openapi: conversion of the schema.json format to OpenAPI. Supersedes elasticsearch-openapi.
• compiler-wasm-lib: a WebAssembly library that exposes features of this workspace, to allow its use from the larger schema toolchain.
• openapi_to_clients_schema: experimental, incomplete, work in progress: translate an OpenAPI specification to an Elasticsearch schema that can be used as input for code generation.

Building

The output of this directory is the compiler-wasm-lib WebAssembly library. It must be built and committed in this repository every time the Rust code is changed. Use make compiler-wasm-lib to build it.
