Struct hyper::server::Server

source · [−]

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

Expand description

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

source

impl Server<I, ()>

source

pub fn builder(incoming: I) -> Builder

Starts a Builder with the provided incoming stream.

source

impl Server<AddrIncoming, ()>

source

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.

source

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

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

source

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

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

source

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

source

pub fn local_addr(&self) -> SocketAddr

Returns the local address that this server is bound to.

source

impl<I, IO, IE, S, E, B> Server<I, S, E>where
 I: Accept<Conn = IO, Error = IE>,
 IE: Into<Box<dyn StdError + Send + Sync>>,
 IO: AsyncRead + AsyncWrite + Unpin + Send + 'static,
 S: MakeServiceRef<IO, Body, ResBody = B>,
 S::Error: Into<Box<dyn StdError + Send + Sync>>,
 B: HttpBody + 'static,
 B::Error: Into<Box<dyn StdError + Send + Sync>>,
 E: ConnStreamExec<<S::Service as HttpService<Body>>::Future, B>,

source

pub fn with_graceful_shutdown<F>(self, signal: F) -> Graceful<I, S, F, E>where
F: Future<Output = ()>,
E: NewSvcExec<IO, S::Future, S::Service, E, GracefulWatcher>,

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(make_service);

// Prepare some signal for when the server should start shutting down...
let (tx, rx) = tokio::sync::oneshot::channel::<()>();
let graceful = server
    .with_graceful_shutdown(async {
        rx.await.ok();
    });

// Await the `server` receiving the signal...
if let Err(e) = graceful.await {
    eprintln!("server error: {}", e);
}

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