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(());
