unalign

fun <A, B> Iterable<Ior<A, B>>.unalign(): Pair<List<A>, List<B>>

splits a union into its component parts.

import arrow.core.*

fun main(args: Array<String>) {
  //sampleStart
  val result =
   listOf(("A" to 1).bothIor(), ("B" to 2).bothIor(), "C".leftIor())
     .unalign()
  //sampleEnd
  println(result)
}

inline fun <A, B, C> Iterable<C>.unalign(fa: (C) -> Ior<A, B>): Pair<List<A>, List<B>>

after applying the given function, splits the resulting union shaped structure into its components parts

import arrow.core.*

fun main(args: Array<String>) {
  //sampleStart
  val result =
     listOf(1, 2, 3).unalign {
       it.leftIor()
     }
  //sampleEnd
  println(result)
}
