This crate provides a wrapper type for making long-running service loops cancellable.
Let's dive right in with an example. For further details see
Cancellable.
```rust // impl Cancellable for Service { .. } let s = Service::new();
// start the service loop on a new thread let h = s.spawn();
// get a handle that allows cancelling the service loop let exit = h.canceller();
// spin up a new thread that will handle exit signals thread::spawn(move || { // this might catch Ctrl-C from the user, wait for a particular packet, // or for any other condition that signals that the service should exit // cleanly. in this case, we just terminate after a fixed amount of time. thread::sleep(time::Duration::from_secs(1));
// tell the service loop to exit at the first opportunity
exit.cancel();
});
// block until the service loop exits or errors. h.wait().unwrap(); ```
