combine
fun <A, B> Ior<A, B>.combine(other: Ior<A, B>, combineA: (A, A) -> A, combineB: (B, B) -> B): Ior<A, B>(source)
fun <A, B> Either<A, B>.combine(other: Either<A, B>, combineLeft: (A, A) -> A, combineRight: (B, B) -> B): Either<A, B>(source)
Combine two Either values. If both are Right then combine both B values using combineRight or if both are Left then combine both A values using combineLeft, otherwise it returns the this
or fallbacks to other in case this
is Left.
Combines two maps using combine to combine values for the same key.
