pub struct DynAnonReceiver<'a, T: Clone>(/* private fields */);
Expand description
A receiver that cannot .await
value, which holds a dynamic reference to a Watch
channel.
This is an alternative to AnonReceiver
with a simpler type definition, at the expense of
some runtime performance due to dynamic dispatch.
Methods from Deref<Target = AnonRcv<'a, T, dyn WatchBehavior<T> + 'a>>§
Sourcepub fn try_get(&mut self) -> Option<T>
pub fn try_get(&mut self) -> Option<T>
Tries to get the current value of the Watch
without waiting, marking it as seen.
Sourcepub fn try_get_and<F>(&mut self, f: F) -> Option<T>
pub fn try_get_and<F>(&mut self, f: F) -> Option<T>
Tries to get the current value of the Watch
if it matches the predicate
function f
without waiting, marking it as seen.
Sourcepub fn try_changed(&mut self) -> Option<T>
pub fn try_changed(&mut self) -> Option<T>
Tries to get the new value of the watch without waiting, marking it as seen.
Sourcepub fn try_changed_and<F>(&mut self, f: F) -> Option<T>
pub fn try_changed_and<F>(&mut self, f: F) -> Option<T>
Tries to get the new value of the watch which satisfies the predicate
function f
and returns the new value without waiting, marking it as seen.
Sourcepub fn contains_value(&self) -> bool
pub fn contains_value(&self) -> bool
Checks if the Watch
contains a value. If this returns true,
then awaiting Rcv::get
will return immediately.
