pub struct WakerRef<'a> { /* private fields */ }
Expand description

A Waker that is only valid for a given lifetime.

Note: this type implements Deref<Target = Waker>, so it can be used to get a &Waker.

Implementations

Create a new WakerRef from a Waker reference.

Create a new WakerRef from a Waker that must not be dropped.

Note: this if for rare cases where the caller created a Waker in an unsafe way (that will be valid only for a lifetime to be determined by the caller), and the Waker doesn’t need to or must not be destroyed.

Methods from Deref<Target = 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.
