Structures and tools to parse, navigate and validate OpenAPI v3.1 specifications.

Note that due to v3.1 being a breaking change from v3.0, you may have trouble correctly parsing specs in the older format.

Example

let yaml = std::fs::read_to_string("path/to/openapi.yml").unwrap();

match oas3::from_yaml(yaml) {
  Ok(spec) => println!("spec: {:?}", spec),
  Err(err) => println!("error: {}", err)
}
