class AddToCounterAction(pydepot.Action):
def __init__(self, value: int):
self.value: int = value

class AddToCounterReducer(pydepot.Reducer[AddToCounterAction, State]):
@property
def action_type(self) -> type[AddToCounterAction]:
return AddToCounterAction

def apply(self, action: AddToCounterAction, state: State) -> State:
return State(counter=state.counter + action.value)

class CounterSubscriber(pydepot.StoreSubscriber[State]):
def on_state(self, state: State) -> None:
print(f"The counter has changed to {state.counter}.")

def main() -> None:
store = pydepot.Store(initial_state=State(counter=0))
store.register(AddToCounterReducer())

subscriber = CounterSubscriber()
store.subscribe(subscriber)

store.dispatch(AddToCounterAction(value=42))
