unalign

fun <K, A, B> Map<K, Ior<A, B>>.unalign(): Pair<Map<K, A>, Map<K, B>>

Splits a union into its component parts.

import arrow.core.*

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

fun <K, A, B, C> Map<K, C>.unalign(fa: (Entry<K, C>) -> Ior<A, B>): Pair<Map<K, A>, Map<K, 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 =
     mapOf("1" to 1, "2" to 2, "3" to 3)
       .unalign { it.leftIor() }
  //sampleEnd
  println(result)
}
