Struct reactive_state::Listener[−][src]

pub struct Listener<State, Event>(_);
Expand description

A weak reference to a callback function (usually Callback) which is notified of changes to Store State, and Events produced by the store.

See Callback for more information about how this is typically used.

Implementations

impl<State, Event> Listener<State, Event>[src]

pub fn as_callback(&self) -> Option<Callback<State, Event>>[src]

Attempt to upgrade the weak reference in this listener to a Callback, otherwise if unable to, returns None.
