<commit_before>//! HTTP Server
//!
//! A `Server` is created to listen on a port, parse HTTP requests, and hand
//! them off to a `Service`.
//!
//! There are two levels of APIs provide for constructing HTTP servers:
//!
//! - The higher-level [`Server`](Server) type.
//! - The lower-level [conn](conn) module.
//!
//! # Server
//!
//! The [`Server`](Server) is main way to start listening for HTTP requests.
//! It wraps a listener with a [`NewService`](::service), and then should
//! be executed to start serving requests.
//!
//! ## Example
//!
//! ```no_run
//! extern crate hyper;
//!
//! use hyper::{Body, Response, Server};
//! use hyper::service::service_fn_ok;
//!
//! # #[cfg(feature = "runtime")]
//! fn main() {
//! # use hyper::rt::Future;
//!     // Construct our SocketAddr to listen on...
//!     let addr = ([127, 0, 0, 1], 3000).into();
//!
//!     // And a NewService to handle each connection...
//!     let new_service = || {
//!         service_fn_ok(|_req| {
//!             Response::new(Body::from("Hello World"))
//!         })
//!     };
//!
//!     // Then bind and serve...
//!     let server = Server::bind(&addr)
//!         .serve(new_service);
//!
//!     // Finally, spawn `server` onto an Executor...
//!     hyper::rt::run(server.map_err(|e| {
//!         eprintln!("server error: {}", e);
//!     }));
//! }
//! # #[cfg(not(feature = "runtime"))]
//! # fn main() {}
