Server

Struct Server 

Source
pub struct Server { /* private fields */ }
Expand description

The HTTP server that owns and dispatches a collection of SocketType routes.

Build routes through the ServerMechanism builder chain, register each with mechanism, then start the server with serve.

§Example


let mut server = Server::default();

server
    .mechanism(
        ServerMechanism::get("/ping")
            .onconnect(|| async { reply!(json => Pong { ok: true }) })
    )
    .mechanism(
        ServerMechanism::delete("/session")
            .onconnect(|| async { reply!(message => warp::reply(), status => Status::NoContent) })
    );

// Blocks forever — call only to actually run the server:
// server.serve(([0, 0, 0, 0], 8080)).await;

§Caution

Calling serve with no routes registered will panic.

Implementations§

Source§

impl Server

Source

pub fn mechanism(&mut self, mech: SocketType) -> &mut Self

Registers a SocketType route on this server.

Routes are evaluated in registration order. Returns &mut Self for method chaining.

Source

pub async fn serve(self, addr: impl Into<SocketAddr>)

Binds to addr and starts serving all registered routes.

This is an infinite async loop — it never returns under normal operation.

§Panics

Panics immediately if no routes have been registered via mechanism.

Source

pub async fn serve_with_graceful_shutdown( self, addr: impl Into<SocketAddr>, shutdown: impl Future<Output = ()> + Send + 'static, )

Binds to addr, serves all registered routes, and shuts down gracefully when shutdown resolves.

Equivalent to calling serve_from_listener with an address instead of a pre-bound listener.

§Example
use tokio::sync::oneshot;

let (tx, rx) = oneshot::channel::<()>();
// ... build server and mount routes ...
// trigger shutdown later by calling tx.send(())
server.serve_with_graceful_shutdown(([127, 0, 0, 1], 8080), async move {
    rx.await.ok();
}).await;
Source

pub async fn serve_from_listener( self, listener: TcpListener, shutdown: impl Future<Output = ()> + Send + 'static, )

Serves all registered routes from an already-bound listener, shutting down gracefully when shutdown resolves.

Use this when port 0 is passed to TcpListener::bind and you need to know the actual OS-assigned port before the server starts (e.g. to open a browser to the correct URL).

§Example
use tokio::net::TcpListener;
use tokio::sync::oneshot;

let listener = TcpListener::bind("127.0.0.1:0").await?;
let port = listener.local_addr()?.port();
println!("Will listen on port {port}");

let (tx, rx) = oneshot::channel::<()>();
// ... build server and mount routes ...
server.serve_from_listener(listener, async move { rx.await.ok(); }).await;
