Methods

mapN<I>(Function8<A, B, C, D, E, F, G, H, I> fn) → Either<EE, I>

Available on (Either<EE, A>, Either<EE, B>, Either<EE, C>, Either<EE, D>, Either<EE, E>, Either<EE, F>, Either<EE, G>, Either<EE, H>), provided by the Tuple8EitherOps 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, C, D, E, F, G, H)>

Available on (Either<EE, A>, Either<EE, B>, Either<EE, C>, Either<EE, D>, Either<EE, E>, Either<EE, F>, Either<EE, G>, Either<EE, H>), provided by the Tuple8EitherOps 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.
