Crate async_events_emitter

Event Emitter Library

async-events-emitter is a Rust library providing an implementation of an event handling system. It allows users to define custom events and handlers, and emit events that are processed asynchronously.

Usage

use async_events_emitter::*;
use async_trait::async_trait;
 
// Define your events
#[derive(Debug, Clone)]
struct MyEvent;
 
// Impl the EventHandler trait
#[async_trait]
impl EventHandler<MyEvent> for MyHandler {
    async fn handle_event(&self, event: MyEvent) {
        // TODO: Process and handle your event async
    }
}
 
let ee = EventEmitter::new();
// Init the handler
let handler = EventHandler;
// Attach the handler to your event
ee.on::<MyEvent>(handler);
// Now emit the event
ee.emit(MyEvent);

Features

• Define custom events.
• Register asynchronous event handlers.
• Emit events to be handled by registered handlers.
