Struct ConditionGuard

pub struct ConditionGuard<'a, T>(/* private fields */);

Guard returned by lock.

Implementations

impl<'a, T> ConditionGuard<'a, T>

pub fn add_waker(&mut self, waker_entry: Pin<&mut WakerEntry<T>>, waker: Waker)

Adds the waker entry to the condition’s list of wakers.

pub fn drain_wakers<'b>(&'b mut self) -> Drainer<'b, 'a, T>

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.

pub fn waker_count(&self) -> usize

Returns the number of wakers registered with the condition.

Trait Implementations

impl<T> Deref for ConditionGuard<'_, T>

type Target = T

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T> DerefMut for ConditionGuard<'_, T>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.
