Crate ignis_events 

ignis_events

ignis_events crate provides utilities to manage events and callbacks.

It allows users to listen for events and execute the registered callbacks when an event occurs.

Example

use ignis_events::Event;

struct MyService {
    on_something_happened: Event<u32>,
}

impl MyService {
    fn new() -> Self {
        Self {
            on_something_happened: Event::<u32>::new(),
        }
    }
}

let service = MyService::new();
let handle = service.on_something_happened.connect(|arg| {
    println!("Something happened");
    assert_eq!(*arg, 67);
});

// NOTE: usually you must not emit events by yourself.
// It should be done by the struct owning the event.
service.on_something_happened.emit(&67);

// Disconnect when you do not need to invoke this callback anymore
service.on_something_happened.disconnect(handle);
