    //! Actix web is a small, pragmatic, and extremely fast web framework
    //! for Rust.
    //!
    //! ```rust
    //! use actix_web::{server, App, Path, Responder};
    //! # use std::thread;
    //!
    //! fn index(info: Path<(String, u32)>) -> impl Responder {
    //!     format!("Hello {}! id:{}", info.0, info.1)
    //! }
    //!
    //! fn main() {
    //!     # thread::spawn(|| {
    //!     server::new(|| {
    //!         App::new().resource("/{name}/{id}/index.html", |r| r.with(index))
    //!     }).bind("127.0.0.1:8080")
    //!         .unwrap()
    //!         .run();
    //!     # });
    //! }
    //! ```
    //!
    //! ## 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](server/struct.HttpServer.html): This struct
    //!   represents an HTTP server instance and is used to instantiate and
    //!   configure servers.
    //!
    //! * [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

    //! * Built on top of [Actix actor framework](https://github.com/actix/actix)
    //! * Supported Rust version: 1.26 or later
    //!
    //! ## Package feature
    //!

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
