[−][src]Struct geng_core::prelude::futures::task::WakerRef
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
impl<'a> WakerRef<'a>
[src]
pub fn new(waker: &'a Waker) -> WakerRef<'a>
[src]
pub fn new_unowned(waker: ManuallyDrop<Waker>) -> WakerRef<'a>
[src]
Methods from Deref<Target = Waker>
pub fn wake_by_ref(&self)
1.36.0[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
1.36.0[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 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.
