Methods

mapN<C>(Function2<A, B, C> fn) → Either<EE, C>

Available on (Either<EE, A>, Either<EE, B>), provided by the Tuple2EitherOps extension

Applies fn to the values of each respective tuple member if all values are a Right. If any item is a Left, the first Left encountered will be returned.

tupled() → Either<EE, (A, B)>

Available on (Either<EE, A>, Either<EE, B>), provided by the Tuple2EitherOps extension

If all items of this tuple are a Right, the respective items are turned into a tuple and returned as a Right. If any item is a Left, the first Left encountered is returned.
