Implementations

impl<T, const N: usize> WakerPool<T, N>

pub const fn new() -> Self

pub fn register(&self) -> Result<WakerToken<'_, T, N>, ()>

Hold a place in the pool

pub fn wake_one(&self) -> bool

Wake a waiter, and remove it.

Returns false if the pool is empty.

pub fn wake_all(&self) -> usize

Wake all waiter, and remove it.

returns the number of had waked

pub fn retain(&self, f: impl FnMut(&WakerEntity<T>) -> bool)

Retains only the elements specified by the predicate.

In other words, remove all elements e such that f(&e) returns false. This method operates in place, visiting each element exactly once in the original order, but not preserves the order of the retained elements.
