Progenitor is a Rust crate that generates opinionated async client code from OpenAPI 3.0.x API descriptions, producing a typed `Client` with methods for each operation. It can also generate a CLI for the API and strongly-typed httpmock helpers for testing.

Use cases

• generate a Rust client from an OpenAPI spec
• create a typed mock server for an OpenAPI API
• build a CLI to call an OpenAPI service
• generate async Rust code with pagination streams from an API description
• consume a Dropshot-generated API in Rust

When to choose

• you have an OpenAPI 3.0.x document (especially Dropshot-generated) and want idiomatic async Rust client code
• you want compile-time code generation via macro or build script from your spec
• you need typed mocks or a ready-made CLI for an API

When to avoid

• your OpenAPI document uses features Progenitor does not yet support
• you need a runtime generic client rather than generated code
• you target languages other than Rust
