1.36.0[−][src]Struct std::task::Waker
A Waker is a handle for waking up a task by notifying its executor that it
is ready to be run.
This handle encapsulates a RawWaker instance, which defines the
executor-specific wakeup behavior.
Methods
impl Waker[src]
pub fn wake(self)[src]
Wake up the task associated with this Waker.
pub fn wake_by_ref(&self)[src]
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().
pub fn will_wake(&self, other: &Waker) -> bool[src]
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 Wakers would awaken the same task. However, if this function
returns true, it is guaranteed that the Wakers will awaken the same task.
This function is primarily used for optimization purposes.
pub unsafe fn from_raw(waker: RawWaker) -> Waker[src]
Creates a new Waker from RawWaker.
The behavior of the returned Waker is undefined if the contract defined
in RawWaker's and RawWakerVTable's documentation is not upheld.
Therefore this method is unsafe.
