Implementations

impl<T: ForLifetime> EventSource<T>

pub const fn new() -> Self

Create new EventSource

pub fn with_emitter(&self, emit_fn: impl FnOnce(EventEmitter<'_, T>))

Create EventEmitter for this EventSource

pub fn on<F>(&self, listener: F) -> EventFnFuture<'_, F, T> where F: FnMut(T::Of<'_>, &mut ControlFlow) + Send + Sync,

Listen events

It can be called after woken if another event occurred before task continue

pub async fn once<F, R>(&self, listener: F) -> Option<R>where F: FnMut(T::Of<'_>, &mut ControlFlow) -> Option<R> + Send + Sync, R: Send + Sync,

Listen event until listener returns Option::Some

Unlike EventSource::on it will ignore every events once listener is done or returns with Option::Some.
