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 { -//!
