Trait AddListener 

pub trait AddListener<T> {
    // Required method
    fn add_listener(&self, f: T) -> Subscription;
}

An extension trait for AddListener::add_listener, which we want to take a variety of function-like arguments for readability.

Required Methods

fn add_listener(&self, f: T) -> Subscription

Register a listener to this PubSub<_>, which will be automatically deregistered when the return Subscription is dropped.

Arguments

• f The callback, presumably a function-like type.
