Struct hyper::server::Server

pub struct Server<I, S, E = Exec> { /* private fields */ }

A listening HTTP server that accepts connections in both HTTP1 and HTTP2 by default.

Server is a Future mapping a bound listener with a set of service handlers. It is built using the Builder, and the future completes when the server has been shutdown. It should be run by an Executor.

Implementations

impl<I> Server<I, ()>

pub fn builder(incoming: I) -> Builder<I>

Starts a Builder with the provided incoming stream.

impl Server<AddrIncoming, ()>

pub fn bind(addr: &SocketAddr) -> Builder<AddrIncoming>

Binds to the provided address, and returns a Builder.

Panics

This method will panic if binding to the address fails. For a method to bind to an address and return a Result, see Server::try_bind.

pub fn try_bind(addr: &SocketAddr) -> Result<Builder<AddrIncoming>>

Tries to bind to the provided address, and returns a Builder.

pub fn from_tcp(
    listener: StdTcpListener
) -> Result<Builder<AddrIncoming>, Error>

Create a new instance from a std::net::TcpListener instance.

impl<S, E> Server<AddrIncoming, S, E>

pub fn local_addr(&self) -> SocketAddr

Returns the local address that this server is bound to.

impl<I, S, E, B> Server<I, S, E> where
    I: Stream,
    I::Error: Into<Box<dyn StdError + Send + Sync>>,
    I::Item: AsyncRead + AsyncWrite + Send + 'static,
    S: MakeServiceRef<I::Item, ReqBody = Body, ResBody = B>,
    S::Error: Into<Box<dyn StdError + Send + Sync>>,
    S::Service: 'static,
    B: Payload,
    E: H2Exec<<S::Service as Service>::Future, B>,
    E: NewSvcExec<I::Item, S::Future, S::Service, E, GracefulWatcher>, 

pub fn with_graceful_shutdown<F>(self, signal: F) -> Graceful<I, S, F, E> where
    F: Future<Item = ()>, 

Prepares a server to handle graceful shutdown when the provided future completes.

Example

// Make a server from the previous examples...
let server = Server::bind(&([127, 0, 0, 1], 3000).into())
    .serve(new_service);

// Prepare some signal for when the server should start
// shutting down...
let (tx, rx) = futures::sync::oneshot::channel::<()>();

let graceful = server
    .with_graceful_shutdown(rx)
    .map_err(|err| eprintln!("server error: {}", err));

// Spawn `server` onto an Executor...
hyper::rt::spawn(graceful);

// And later, trigger the signal by calling `tx.send(())`.
let _ = tx.send(());
