I ran into the issue a couple of times where I spawned a task with async_std::task::spawn, and I was interested in getting an indication of the state of this task.

In my specific case I'm spawning up a task that takes data from a TcpStream and sends it to a Sender. This task does not have a noticeable output, however I would like to periodically check if this task is still running and didn't panic or something.

let handle = task::spawn(receiver_loop(stream.clone(), self.sender.clone()));
self.stream = Some((
	stream,
	handle
));

// Periodically run this:
if let Some((_, handle)) = self.stream.as_mut() {
	if handle.task().state() == TaskState::Completed {
		// Something went wrong
		log_error("...");
		self.reconnect()
	}
}
