[−][src]Struct revent::Topic
A topic to which objects can subscribe.
Methods
impl<T: ?Sized> Topic<T>[src]
pub fn new() -> Self[src]
Create a new topic object.
pub fn insert(&mut self, item: Rc<RefCell<T>>)[src]
Insert a new subscriber into this topic.
Appends the subscriber to the end of the subscriber list.
pub fn emit<F>(&mut self, caller: F) where
F: FnMut(&mut T), [src]
F: FnMut(&mut T),
Modify all subscribers using the given closure.
Iterates over all subscribers in subscription order.
pub fn remove<'a, F>(
&'a mut self,
caller: F
) -> impl Iterator<Item = Rc<RefCell<T>>> + 'a where
F: FnMut(&mut T) -> bool + 'a, [src]
&'a mut self,
caller: F
) -> impl Iterator<Item = Rc<RefCell<T>>> + 'a where
F: FnMut(&mut T) -> bool + 'a,
Remove subscribers from this topic.
Preserves the relative order of subscribers. Returns an iterator over all removed items.
