[−][src]Type Definition redux_rs::Subscription
type Subscription<State> = fn(_: &State);
Function signature for a subscription.
A Subscription will be called, whenever an action is dispatched (and reaches the reducer). It receives a reference to the current state, which might or might not be used.
Example
let mut store = Store::new(reducer, initial_state); let listener: Subscription<State> = |state: &State| { println!("Something changed! New value: {}", state); }; store.subscribe(listener);
