MaybeRecordX<K, J> extension
Methods
-
maybeAsyncCombine<T>({FutureOr<Maybe<T>> firstJust(K)?, FutureOr<Maybe<T>> secondJust(J)?, FutureOr<Maybe<T>> bothJust(K, J)?, FutureOr<Maybe<T>> bothNothing()?})
→ FutureOr<Maybe<T>>
-
Use it to asynchronously combine two different Maybe's into a new one. Input
firstJust to map case where only the first value is Just, secondJust to map case where only the second value is Just, bothJust to map case where both first and second value are Just and bothNothing to map case where both are Nothing
Example:
-
maybeCombine<T>({Maybe<T> firstJust(K)?, Maybe<T> secondJust(J)?, Maybe<T> bothJust(K, J)?, Maybe<T> bothNothing()?})
→ Maybe<T>
