Struct Receiver 

Source 
pub struct Receiver<'a, M: RawMutex, T: Clone>(/* private fields */);
Expand description

A receiver of a Watch channel.

Methods from Deref<Target = Rcv<'a, T, Watch<M, T>>>§

Source

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

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

Source

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

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

Source

pub fn contains_value(&self) -> bool

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