Trait tf_observer::Observable

pub trait Observable<T> {
    fn attach(&mut self, observer: Weak<Mutex<Box<dyn Observer<T> + Send>>>);
    fn detach(&mut self, observer: Weak<Mutex<Box<dyn Observer<T> + Send>>>);
}

A Observable that can be observed by Observer.

T is the message being sent from the Observable to the Observer. This should be implemented using the ObserverList.

Required methods

fn attach(&mut self, observer: Weak<Mutex<Box<dyn Observer<T> + Send>>>)

Attach a Observer to the Observable.

Should be implemented using ObserverList::attach.

fn detach(&mut self, observer: Weak<Mutex<Box<dyn Observer<T> + Send>>>)

Detach a Observer to the Observable.

Should be implemented using ObserverList::detach.

impl<T> Observable<T> for ObserverList<T>
