roas

Apache-2.0

Rust crates for OpenAPI, AsyncAPI, Overlay and Arazzo — every version of each — with a validation CLI. Documents are parsed into typed Rust, validated against the specification, converted between versions, and, in Arazzo's case, executed by a dedicated executor crate. One of two Rust implementations found and the only one with a detectable license and current commits.

Arazzo

Specifications it implements

What this tool does to each specification, in the role vocabulary. Follow a standard through to standards.apievangelist.com for what it actually specifies.

Where it applies

Jobs this tool actually does, and the surface each one is exercised on.

Validate an Arazzo document from a Rust toolchain, or embed the typed model in a Rust service.

Validation is offline and deterministic; the executor crate makes real calls and is not.
