When I was using the hyper server, I wanted to be able to shut it down gracefully. So I was using with_graceful_shutdown() to get a Future.
The following code works fine.
let signer = Arc::new(Notify::new());
let waiter = signer.clone();
let graceful = server.with_graceful_shutdown(waiter.notified());
tokio::spawn(async move {
time.sleep(ONE_SEC).await;
signer.notify_one();
});
graceful.await
...
But now I want to save the `graceful` variable above into a structure so that I can easily call .await at the right time to start the server, instead of starting it directly in this function.
However, I so want to have a hard time writing the exact type of `graceful`. Can someone help me?
