//! OpenAPI support for Poem.
//!
//! `Poem-openapi` allows you to easily implement APIs that comply with the
//! `OpenAPIv3` specification. It uses procedural macros to generate a lots of
//! boilerplate code, so that you only need to focus on the more
//! important business implementations.
//!
//! * [Book](https://poem-web.github.io/poem/)
//! * [Docs](https://docs.rs/poem-openapi)
//! * [Cargo package](https://crates.io/crates/poem-openapi)
//!
//! ## Features
//!
//! * **Type safety** If your codes can be compiled, then it is fully compliant
//!   with the `OpenAPI v3` specification.
//! * **Rustfmt friendly** Do not create any DSL that does not conform to Rust's
//!   syntax specifications.
//! * **IDE friendly** Any code generated by the procedural macro will not be
//!   used directly.
//! * **Minimal overhead** All generated code is necessary, and there is almost
//!   no overhead.
//!
//! ## Crate features
//!
//! To avoid compiling unused dependencies, Poem gates certain features, some of
//! which are disabled by default:
//!
//! | Feature    | Description                      | Default enabled |
//! | ---------- | -------------------------------- | --------------- |
//! | chrono     | Integrate with the [`chrono` crate](https://crates.io/crates/chrono). | :x: |
//! | swagger-ui | Add swagger UI support  | :heavy_check_mark: |
//! | rapidoc    | Add RapiDoc support   | :heavy_check_mark: |
//!
//! ## Example
//!
//! ```ignore
//! use poem::{listener::TcpListener, Route};
//! use poem_openapi::{param::Query, payload::PlainText, OpenApi, OpenApiService};
//!
//! struct Api;
//!
//! #[OpenApi]
//! impl Api {
//!     #[oai(path = "/hello", method = "get")]
//!     async fn index(&self, name: Query<Option<String>>) -> PlainText<String> {
//!         match name.0 {
//!             Some(name) => PlainText(format!("hello, {}!", name)),
//!             None => PlainText("hello!".to_string()),
//!         }
//!     }
//! }
//!
//! #[tokio::main]
//! async fn main() -> Result<(), std::io::Error> {
//!     let api_service =
//!         OpenApiService::new(Api, "Hello World", "1.0").server("http://localhost:3000/api");
//!     let ui = api_service.swagger_ui();
//!     let app = Route::new().nest("/api", api_service).nest("/", ui);
//!
//!     poem::Server::new(TcpListener::bind("127.0.0.1:3000"))
//!         .run(app)
//!         .await
//! }
//! ```
//!
//! ## Run example
//!
//! Open `http://localhost:3000/ui` in your browser, you will see the `Swagger UI` that contains these API definitions.
//!
//! ```shell
//! > cargo run --example hello_world
//!
//! > curl http://localhost:3000
//! hello!
//!
//! > curl http://localhost:3000\?name\=sunli
//! hello, sunli!
//! ```
