pub struct DynSender<'a, T: Clone>(/* private fields */);
Expand description
A sender which holds a dynamic reference to a Watch
channel.
This is an alternative to Sender
with a simpler type definition,
Methods from Deref<Target = Snd<'a, T, dyn WatchBehavior<T> + 'a>>§
Sourcepub fn clear(&self)
pub fn clear(&self)
Clears the value of the Watch
.
This will cause calls to Rcv::get
to be pending.
Sourcepub fn try_get_and<F>(&self, f: F) -> Option<T>
pub fn try_get_and<F>(&self, f: F) -> Option<T>
Tries to peek the current value of the Watch
if it matches the predicate
function f
.
Sourcepub fn contains_value(&self) -> bool
pub fn contains_value(&self) -> bool
Returns true if the Watch
contains a value.
Sourcepub fn send_modify<F>(&self, f: F)
pub fn send_modify<F>(&self, f: F)
Modify the value of the Watch
using a closure.
Sourcepub fn send_if_modified<F>(&self, f: F)
pub fn send_if_modified<F>(&self, f: F)
Modify the value of the Watch
using a closure. The closure must return
true
if the value was modified, which notifies all receivers.
