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.

Methods from Deref<Target = Waker>§
1.36.0 · Sourcepub fn wake_by_ref(&self)
pub fn wake_by_ref(&self)
Wakes 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().
1.36.0 · Sourcepub fn will_wake(&self, other: &Waker) -> bool
pub fn will_wake(&self, other: &Waker) -> bool
Returns true if this Waker and another Waker would awake 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 — for example,
this type’s clone_from implementation uses it to
avoid cloning the waker when they would wake the same task anyway.
1.83.0 · Sourcepub fn vtable(&self) -> &'static RawWakerVTable
pub fn vtable(&self) -> &'static RawWakerVTable
Gets the vtable pointer used to create this Waker.
