Tuple8EitherOps<E, T1, T2, T3, T4, T5, T6, T7, T8>

extension Tuple8EitherOps<E, T1, T2, T3, T4, T5, T6, T7, T8> on Record

Provides additional functions on tuple with 8 Eithers.

Properties

tupled extension no setter

Either<E, Record> get tupled

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.

Available on Record, provided by the Tuple8EitherOps<E, T1, T2, T3, T4, T5, T6, T7, T8> extension

Implementation

Either<E, (T1, T2, T3, T4, T5, T6, T7, T8)> get tupled =>
    init.tupled.flatMap((x) => last.map(x.appended));

Methods

mapN() extension

Either<E, T9> mapN<T9>(T9 Function(T1, T2, T3, T4, T5, T6, T7, T8) fn)

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.
