Struct core::task::Waker1.36.0[][src]

#[repr(transparent)]
pub struct Waker { /* fields omitted */ }
Expand description

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.

Implements Clone, Send, and Sync.

Implementations

Wake up the task associated with this Waker.

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().

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.

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.
