pub struct WakerList(/* private fields */);

A waker list.

Implementations

impl WakerList

pub fn new() -> Self

Returns a new waker list.

pub fn new_entry(&self) -> WakerEntry

Returns a new entry that can be later added to this list.

pub fn len(&self) -> usize

Returns the number of wakers in the list.

pub fn drain(&self) -> Drainer<'_>

Returns an iterator that will drain all wakers. Whilst the drainer exists, a lock is held which will prevent new wakers from being added to the list, so depending on your use case, you might wish to collect the wakers before calling wake on each waker. NOTE: If the drainer is dropped, this will not drain elements not visited.
