Struct DynAnonReceiver 

pub struct DynAnonReceiver<'a, T: Clone>(/* private fields */);

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>>

pub fn try_get(&mut self) -> Option<T>

Tries to get the current value of the Watch without waiting, marking it as seen.

pub fn try_get_and<F>(&mut self, f: F) -> Option<T>

where F: Fn(&T) -> bool,

Tries to get the current value of the Watch if it matches the predicate function f without waiting, marking it as seen.

pub fn try_changed(&mut self) -> Option<T>

Tries to get the new value of the watch without waiting, marking it as seen.

pub fn try_changed_and<F>(&mut self, f: F) -> Option<T>

where F: Fn(&T) -> bool,

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.

pub fn contains_value(&self) -> bool

Checks if the Watch contains a value. If this returns true, then awaiting Rcv::get will return immediately.
