mapAsyncJust<K> method

FutureOr<Maybe<K>> mapAsyncJust<K>(FutureOr<Maybe<K>> combiner(T))

A Method to chain async access to data held by the Maybe. If this is Nothing returns Nothing, if this is Just, returns the result of the combiner method over the value inside Just

Implementation

FutureOr<Maybe<K>> mapAsyncJust<K>(FutureOr<Maybe<K>> Function(T) combiner) {
  return switch (this) {
    Nothing<T>() => Nothing<K>(),
    Just<T>(:final value) => combiner(value),
  };
}
