Struct reactive_state::middleware::simple_logger::SimpleLoggerMiddleware

pub struct SimpleLoggerMiddleware { /* fields omitted */ }

This is supported on feature="simple_logger" only.

Logging Middleware which uses the log macros to publish actions/events that occur within the Store.

See simple_logger for more details.

Trait Implementations

impl Default for SimpleLoggerMiddleware

fn default() -> Self

Returns the "default value" for a type.

impl<State, Action, Event, Effect> Middleware<State, Action, Event, Effect> for SimpleLoggerMiddleware where
    Event: StoreEvent + Clone + Hash + Eq + Debug,
    State: Debug,
    Action: Debug,
    Effect: Debug, 

fn on_reduce(
    &self,
    store: &Store<State, Action, Event, Effect>,
    action: Option<&Action>,
    reduce: ReduceFn<State, Action, Event, Effect>
) -> ReduceMiddlewareResult<Event, Effect>

This method is invoked by the Store during a Store::dispatch() just before the Action is sent to the Reducer. It is necessary to call the provided reduce function, which executes subsequent middleware and runs the Reducer, and usually the events produced by the reduce function are returned from this method.

fn process_effect(
    &self,
    _store: &Store<State, Action, Event, Effect>,
    effect: Effect
) -> Option<Effect>

Process an Effect. Returns None if the effect was processed/consumed by this handler, otherwise returns Some(effect).

fn on_notify(
    &self,
    store: &Store<State, Action, Event, Effect>,
    events: Vec<Event>,
    notify: NotifyFn<State, Action, Event, Effect>
) -> Vec<Event>

This method is invoked by the Store during a Store::dispatch() after the Reducer has processed the Action and all Middleware::on_reduce() methods have completed, just before resulting events are sent to the store listeners. It is necessary to call the provided notify function, which executes subsequent middleware and then notifies the listeners.
