impl<T> WatchSender<T>
sourcepub fn send(&self, value: T)
pub fn send(&self, value: T)
Send a new message and notify all receivers currently waiting for a message.
sourcepub fn update<F>(&self, f: F) where
F: FnOnce(&mut T),
pub fn update<F>(&self, f: F) where
F: FnOnce(&mut T),
Update the message by a closure and notify all receivers currently waiting for a message.
sourcepub fn subscribe(&self) -> WatchReceiver<T>
pub fn subscribe(&self) -> WatchReceiver<T>
Create a new receiver for the channel.
Any messages sent before this method was called are considered seen by the new receiver.
