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<I> Server<I, ()>

source

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

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>, Error>

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

source

pub fn from_tcp(listener: TcpListener) -> 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 Error + Sync + Send>>, IO: AsyncRead + AsyncWrite + Unpin + Send + 'static, S: MakeServiceRef<IO, Body, ResBody = B>, <S as MakeServiceRef<IO, Body>>::Error: Into<Box<dyn Error + Sync + Send>>, B: Body + 'static, <B as Body>::Error: Into<Box<dyn Error + Sync + Send>>, E: ConnStreamExec<<<S as MakeServiceRef<IO, Body>>::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 as MakeServiceRef<IO, Body>>::Future, <S as MakeServiceRef<IO, Body>>::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(());
