//! Support crate for Swagger codegen.
//!
//! # Crate features
//!
//! Crate features exist to reduce the dependencies on the crate. Most features
//! should be enabled by the generator when relevant.

//! - **serdevalid** - Enable support for JSON schema based validation
//! - **conversion** - Enable support for Frunk-based conversion - in particular,
//!   [transmogrification](https://docs.rs/frunk/latest/frunk/#transmogrifying)
//!
//! ## Use case support
//!
//! - **client** - Enable support for providing an OpenAPI client
//! - **server** - Enable support for providing an OpenAPI server
//! - **http1** - Enable support for HTTP/1 based APIs - RFC 9112
