[−][src]Struct revent::Signal
Signal of interest, contains subscribers.
Signals are channels on which we can emit events synchronously. This is done by Signal::emit. Signals are not be created by the user directly, but are rather created via the hub and node macros.
Methods
impl<T: ?Sized> Signal<T>[src]
pub fn emit<F>(&mut self, caller: F) where
F: FnMut(&mut T), [src]
F: FnMut(&mut T),
Access all subscribers and apply a closure to each.
Subscribers are iterated in subscription order.
pub fn remove<F>(&mut self, predicate: F) where
F: FnMut(&mut T) -> bool, [src]
F: FnMut(&mut T) -> bool,
Remove subscribers from a topic given a predicate. True removes the item.
Removing items does not perturb relative ordering.
pub fn sort_by<F>(&mut self, compare: F) where
F: FnMut(&T, &T) -> Ordering, [src]
F: FnMut(&T, &T) -> Ordering,
Sorts the topic with a comparator function.
