Implementations
sourceimpl Waker
impl Waker
sourcepub fn wake_by_ref(&self)
pub fn wake_by_ref(&self)
Wake up the task associated with this Waker
without consuming the Waker
.
This is similar to wake
, but may be slightly less efficient in the case
where an owned Waker
is available. This method should be preferred to
calling waker.clone().wake()
.
sourcepub fn will_wake(&self, other: &Waker) -> bool
pub fn will_wake(&self, other: &Waker) -> bool
Returns true
if this Waker
and another Waker
have awoken the same task.
This function works on a best-effort basis, and may return false even
when the Waker
s would awaken the same task. However, if this function
returns true
, it is guaranteed that the Waker
s will awaken the same task.
This function is primarily used for optimization purposes.
