Hey! Listen!

Hey_listen is a collection of event-dispatchers aiming to suit all needs!

Covering synchronous, parallel, and sync-prioritised dispatching to Closures, Enums, Structs, and every other type supporting trait-implementation.

View the examples-folder on how to use each dispatcher.

Everyone is welcome to contribute, check out the CONTRIBUTING.md for further guidance.

Example

Here is a quick example on how to use the event-dispatcher:

extern crate hey_listen;
extern crate parking_lot;

use hey_listen::{EventDispatcher, Listener, SyncDispatcherRequest};
use std::sync::Arc;
use parking_lot::Mutex;

#[derive(Clone, Eq, Hash, PartialEq)]
enum Event {
    EventVariant,
}

struct ListenerStruct {}

impl Listener<Event> for ListenerStruct {
    fn on_event(&mut self, _event: &Event) -> Option<SyncDispatcherRequest> {
        println!("I'm listening! :)");

        None
    }
}

fn main() {
    let listener = Arc::new(Mutex::new(ListenerStruct {}));
    let mut dispatcher: EventDispatcher<Event> = EventDispatcher::default();

    dispatcher.add_listener(Event::EventVariant, &listener);
    dispatcher.dispatch_event(&Event::EventVariant);
}

Installation
