package Xor
Combine with another Xor value.
Combine with another Xor value.
If this Xor is a Left then it will be returned as-is.
If this Xor is a Right and that Xor is a left, then that will be
returned.
If both Xors are Rights, then the Semigroup[BB] instance will be used
to combine both values and return them as a Right.
Note: If both Xors are Lefts then their values are not combined. Use
Validated if you prefer to combine Left values.
Examples:
scala> import cats.data.Xor scala> import cats.implicits._ scala> val l1: Xor[String, Int] = Xor.left("error 1") scala> val l2: Xor[String, Int] = Xor.left("error 2") scala> val r3: Xor[String, Int] = Xor.right(3) scala> val r4: Xor[String, Int] = Xor.right(4) scala> l1 combine l2 res0: Xor[String, Int] = Left(error 1) scala> l1 combine r3 res1: Xor[String, Int] = Left(error 1) scala> r3 combine l1 res2: Xor[String, Int] = Left(error 1) scala> r3 combine r4 res3: Xor[String, Int] = Right(7)
Returns a ValidatedNel representation of this disjunction with the Left value
as a single element on the Invalid side of the NonEmptyList.
