//! Actix web is a small, pragmatic, and extremely fast web framework
//! for Rust.
//!
//! ```rust
//! use actix_web::{web, App, Responder, HttpServer};
//! # use std::thread;
//!
//! fn index(info: web::Path<(String, u32)>) -> impl Responder {
//!     format!("Hello {}! id:{}", info.0, info.1)
//! }
//!
//! fn main() -> std::io::Result<()> {
//!     # thread::spawn(|| {
//!     HttpServer::new(|| App::new().service(
//!         web::resource("/{name}/{id}/index.html").to(index))
//!     )
//!         .bind("127.0.0.1:8080")?
//!         .run()
//!     # });
//!     # Ok(())
//! }
//! ```
//!
//! ## Documentation & community resources
//!
//! Besides the API documentation (which you are currently looking
//! at!), several other resources are available:
//!
//! * [User Guide](https://actix.rs/docs/)
//! * [Chat on gitter](https://gitter.im/actix/actix)
//! * [GitHub repository](https://github.com/actix/actix-web)
//! * [Cargo package](https://crates.io/crates/actix-web)
//!
//! To get started navigating the API documentation you may want to
//! consider looking at the following pages:
//!
//! * [App](struct.App.html): This struct represents an actix-web
//!   application and is used to configure routes and other common
//!   settings.
//!
//! * [HttpServer](struct.HttpServer.html): This struct
//!   represents an HTTP server instance and is used to instantiate and
//!   configure servers.
//!
//! * [web](web/index.html): This module
//!   provide essentials helper functions and types for application registration.
//!
//! * [HttpRequest](struct.HttpRequest.html) and
//!   [HttpResponse](struct.HttpResponse.html): These structs
//!   represent HTTP requests and responses and expose various methods
//!   for inspecting, creating and otherwise utilizing them.
//!
//! ## Features
//!
//! * Supported *HTTP/1.x* and *HTTP/2.0* protocols
//! * Streaming and pipelining
//! * Keep-alive and slow requests handling
//! * `WebSockets` server/client
//! * Transparent content compression/decompression (br, gzip, deflate)
//! * Configurable request routing
//! * Multipart streams
//! * SSL support with OpenSSL or `native-tls`
//! * Middlewares (`Logger`, `Session`, `CORS`, `CSRF`, `DefaultHeaders`)
//! * Supports [Actix actor framework](https://github.com/actix/actix)
//! * Supported Rust version: 1.31 or later
//!
//! ## Package feature
//!
//! * `client` - enables http client
//! * `tls` - enables ssl support via `native-tls` crate
//! * `ssl` - enables ssl support via `openssl` crate, supports `http/2`
//! * `rust-tls` - enables ssl support via `rustls` crate, supports `http/2`
//! * `secure-cookies` - enables secure cookies support, includes `ring` crate as
//!   dependency
//! * `brotli` - enables `brotli` compression support, requires `c`
//!   compiler
//! * `flate2-zlib` - enables `gzip`, `deflate` compression support, requires
//!   `c` compiler
//! * `flate2-rust` - experimental rust based implementation for
//!   `gzip`, `deflate` compression.
