Struct EventManager

pub struct EventManager<Event: Hash + Eq, Payload: Clone> { /* private fields */ }

EventManager is used to get subscribers and emitters, but can also emit events itself

let mut manager: EventManager<StringEvent, i32> = EventManager::new();
let subscriber = manager.once("Event".into());
manager.emit("Event".into(), 57);
assert_eq!(futures::executor::block_on(subscriber), Ok(57));
