Implementations

impl WebLoggerMiddleware

pub fn new() -> Self

pub fn log_level(self, log_level: LogLevel) -> Self

Set the level at which the data from this middleware will be logged to.

pub fn display_type(self, display_type: DisplayType) -> Self

What type of display to use when printing the data from this middleware.

Trait Implementations

impl Default for WebLoggerMiddleware

fn default() -> Self

Returns the “default value” for a type.

impl<State, Action, Event, Effect> Middleware<State, Action, Event, Effect> for WebLoggerMiddleware where
    State: Serialize,
    Action: Serialize + Display,
    Event: Clone + Hash + Eq + Serialize,
    Effect: Serialize, 

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.
