Struct lair_keystore::dependencies::hc_seed_bundle::dependencies::futures::task::WakerRef
[−]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)
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()
.
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
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.
