//! 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
//! * Keep-alive and slow requests handling
//! * `WebSockets` server/client
//! * Transparent content compression/decompression (br, gzip, deflate)
//! * Configurable request routing
//! * Graceful server shutdown
//! * Multipart streams
//! * SSL support with OpenSSL or `native-tls`
//! * Middlewares (`Logger`, `Session`, `CORS`, `CSRF`, `DefaultHeaders`)
//! * Built on top of [Actix actor framework](https://github.com/actix/actix)
//! * Supported Rust version: 1.26 or later
//!
//! ## Package feature
//!
//! * `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`
//! * `uds` - enables support for making client requests via Unix Domain Sockets.
//! Unix only. Not necessary for *serving* requests.
//! * `session` - enables session support, includes `ring` crate as
//! dependency
//! * `brotli` - enables `brotli` compression support, requires `c`
//! compiler
//! * `flate2-c` - enables `gzip`, `deflate` compression support, requires
//! `c` compiler
//! * `flate2-rust` - experimental rust based implementation for
//! `gzip`, `deflate` compression.

//! This middleware is stateless and [based on request
//! headers](https://www.owasp.org/index.php/Cross-Site_Request_Forgery_(CSRF)_Prevention_Cheat_Sheet#Verifying_Same_Origin_with_Standard_Headers).
//!
//! By default requests are allowed only if one of these is true:
//!
//! * The request method is safe (`GET`, `HEAD`, `OPTIONS`). It is the
//! applications responsibility to ensure these methods cannot be used to
//! execute unwanted actions. Note that upgrade requests for websockets are
//! also considered safe.
//! * The `Origin` header (added automatically by the browser) matches one
//! of the allowed origins.
//! * There is no `Origin` header but the `Referer` header matches one of
//! the allowed origins.
//!
//! Use [`CsrfFilter::allow_xhr()`](struct.CsrfFilter.html#method.allow_xhr)
//! if you want to allow requests with unprotected methods via
//! [CORS](../cors/struct.Cors.html).
//!
//! # Example
//!
//! ```
//! # extern crate actix_web;
//! use actix_web::middleware::csrf;
//! use actix_web::{http, App, HttpRequest, HttpResponse};
//!
//! fn handle_post(_: &HttpRequest) -> &'static str {
//! "This action should only be triggered with requests from the same site"
//! }
//!
//! fn main() {
//! let app = App::new()
//! .middleware(
//! csrf::CsrfFilter::new().allowed_origin("https://www.example.com"),
//! )
//! .resource("/", |r| {
//! r.method(http::Method::GET).f(|_| HttpResponse::Ok());
//! r.method(http::Method::POST).f(handle_post);
//! })
//! .finish();
//! }
//! ```
//!
//! In this example the entire application is protected from CSRF.

//! User sessions.
//!
//! Actix provides a general solution for session management. The
//! [**SessionStorage**](struct.SessionStorage.html)
//! middleware can be used with different backend types to store session
//! data in different backends.
//!
//! By default, only cookie session backend is implemented. Other
//! backend implementations can be added.
//!
//! [**CookieSessionBackend**](struct.CookieSessionBackend.html)
//! uses cookies as session storage. `CookieSessionBackend` creates sessions
//! which are limited to storing fewer than 4000 bytes of data, as the payload
//! must fit into a single cookie. An internal server error is generated if a
//! session contains more than 4000 bytes.
//!
//! A cookie may have a security policy of *signed* or *private*. Each has
//! a respective `CookieSessionBackend` constructor.
//!
//! A *signed* cookie may be viewed but not modified by the client. A *private*
//! cookie may neither be viewed nor modified by the client.
//!
//! The constructors take a key as an argument. This is the private key
//! for cookie session - when this value is changed, all session data is lost.
//!
//! In general, you create a `SessionStorage` middleware and initialize it
//! with specific backend implementation, such as a `CookieSessionBackend`.
//! To access session data,
//! [*HttpRequest::session()*](trait.RequestSession.html#tymethod.session)
//! must be used. This method returns a
//! [*Session*](struct.Session.html) object, which allows us to get or set
//! session data.
//!
//! ```rust
//! # extern crate actix_web;

//! // access session data
//! if let Some(count) = req.session().get::<i32>("counter")? {

//! Http server module
//!
//! The module contains everything necessary to setup
//! HTTP server.
//!
//! In order to start HTTP server, first you need to create and configure it
//! using factory that can be supplied to [new](fn.new.html).
//!
//! ## Factory
//!
//! Factory is a function that returns Application, describing how
//! to serve incoming HTTP requests.
//!
//! As the server uses worker pool, the factory function is restricted to trait bounds
//! `Send + Clone + 'static` so that each worker would be able to accept Application
//! without a need for synchronization.
//!
//! If you wish to share part of state among all workers you should
//! wrap it in `Arc` and potentially synchronization primitive like
//! [RwLock](https://doc.rust-lang.org/std/sync/struct.RwLock.html)
//! If the wrapped type is not thread safe.
//!
//! Note though that locking is not advisable for asynchronous programming
//! and you should minimize all locks in your request handlers
//!
//! ## HTTPS Support
//!
//! Actix-web provides support for major crates that provides TLS.
//! Each TLS implementation is provided with [AcceptorService](trait.AcceptorService.html)
//! that describes how HTTP Server accepts connections.
//!
//! For `bind` and `listen` there are corresponding `bind_ssl|tls|rustls` and `listen_ssl|tls|rustls` that accepts
//! these services.
//!
//! **NOTE:** `native-tls` doesn't support `HTTP2` yet
//!
//! ## Signal handling and shutdown
//!
//! By default HTTP Server listens for system signals
//! and, gracefully shuts down at most after 30 seconds.
//!
//! Both signal handling and shutdown timeout can be controlled
//! using corresponding methods.
//!
//! If worker, for some reason, unable to shut down within timeout
//! it is forcibly dropped.
//!
//! ## Example
//!
//! ```rust,ignore
//!extern crate actix;
//!extern crate actix_web;
//!extern crate rustls;
//!
//!use actix_web::{http, middleware, server, App, Error, HttpRequest, HttpResponse, Responder};
//!use std::io::BufReader;
//!use rustls::internal::pemfile::{certs, rsa_private_keys};
//!use rustls::{NoClientAuth, ServerConfig};
//!
//!fn index(req: &HttpRequest) -> Result<HttpResponse, Error> {
//! Ok(HttpResponse::Ok().content_type("text/plain").body("Welcome!"))
//!}
//!
//!fn load_ssl() -> ServerConfig {
//! use std::io::BufReader;
//!
//! const CERT: &'static [u8] = include_bytes!("../cert.pem");
//! const KEY: &'static [u8] = include_bytes!("../key.pem");
//!
//! let mut cert = BufReader::new(CERT);
//! let mut key = BufReader::new(KEY);
//!
//! let mut config = ServerConfig::new(NoClientAuth::new());
//! let cert_chain = certs(&mut cert).unwrap();
//! let mut keys = rsa_private_keys(&mut key).unwrap();
//! config.set_single_cert(cert_chain, keys.remove(0)).unwrap();
//!
//! config
//!}
//!
//!fn main() {
//! let sys = actix::System::new("http-server");
//! // load ssl keys
//! let config = load_ssl();
//!
//! // create and start server at once
//! server::new(|| {
//! App::new()
//! // register simple handler, handle all methods
//! .resource("/index.html", |r| r.f(index))
//! }))
//! }).bind_rustls("127.0.0.1:8443", config)
//! .unwrap()
//! .start();
//!
//! println!("Started http server: 127.0.0.1:8080");
//! //Run system so that server would start accepting connections
//! let _ = sys.run();
//!}
