async fn graceful_shutdown(handle: Handle<SocketAddr>) {
    // Wait 10 seconds.
    sleep(Duration::from_secs(10)).await;

    println!("sending graceful shutdown signal");

    // Signal the server to shutdown using Handle.
    handle.graceful_shutdown(Some(Duration::from_secs(30)));

    // Print alive connection count every second.
    loop {
        sleep(Duration::from_secs(1)).await;

    }
}

pub fn shutdown(&self)

Shutdown the server.

examples/shutdown.rs (line 39)

async fn shutdown(handle: Handle<SocketAddr>) {
    // Wait 20 seconds.
    sleep(Duration::from_secs(20)).await;

    println!("sending shutdown signal");

    // Signal the server to shutdown using Handle.
    handle.shutdown();
}

pub fn graceful_shutdown(&self, duration: Option<Duration>)

Gracefully shutdown the server.

None means indefinite grace period.

        println!("alive connections: {}", handle.connection_count());
    }
}

pub async fn listening(&self) -> Option<A>

Returns local address and port when server starts listening.

Returns None if server fails to bind.
