## [Documentation](https://docs.rs/exit-future) ---- Create a `Signal` and cloneable `Exit` future that fires when `Signal` is fired or dropped. Used to coordinate exit between multiple event-loop threads. ```rust let (signal, exit) = exit_future::signal(); ::std::thread::spawn(move || { // future resolves when signal fires exit.wait(); }); let _ = signal.fire(); // also would fire on drop. ```
