Module riddle_common::eventpub

An event pubsub utility.

Publishers can have multiple subscribers, and subscribers can filter the events they accept.

Example

#[derive(Clone, Eq, PartialEq, Debug)]
enum Message {
    Test
}

fn main() {
    // Make a new pub and sub
    let publisher: EventPub<Message> = EventPub::new();
    let subscriber: EventSub<Message> = EventSub::new();
    publisher.attach(&subscriber);

    // Send a message through the pub
    publisher.dispatch(Message::Test);

    // Take the messages from the sub
    let messages = subscriber.collect();
    assert_eq!(vec![Message::Test], messages);
}
