Implementations§

Source§

impl<T: Clone> Broadcaster<T>

Source

pub fn process_pending_subscriptions(&mut self)

Process all pending subscriptions.

Source

pub fn process_pending_subscriptions_with<F: FnMut(&mut Sender<T>)>( &mut self, f: &mut F, )

Process all pending subscriptions. This method calls a function on each sender before adding it.

Source

pub fn broadcast(&mut self, item: T)

Broadcast a message to all subscribers.

Source

pub fn subscription_manager(&self) -> SubscriptionManager<T>

Get a subscription manager which can be cloned or sent.
