[−][src]Struct rt_graph::Signal
Implements a broadcast-listener / callback / observable pattern.
Signal holds a list of subscriptions, each with a callback closure to run
on the next broadcast.
As rt-graph uses GTK, the terminology (Signal struct and its method names) match
GTK's terms.
Implementations
impl<T: Clone> Signal<T>[src]
pub fn new() -> Signal<T>[src]
Construct a new Signal.
pub fn connect<F>(&mut self, callback: F) -> SubscriptionId where
F: Fn(T) + 'static, [src]
F: Fn(T) + 'static,
Connect a new subscriber that will receive callbacks when the signal is raised.
Returns a SubscriptionId to disconnect the subscription when no longer required.
pub fn raise(&self, value: T)[src]
Notify existing subscribers.
pub fn disconnect(&mut self, id: SubscriptionId)[src]
Disconnect an existing subscription.
