unalign

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

splits an union into its component parts.

import arrow.core.bothIor
import arrow.core.leftIor
import arrow.core.unalign

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

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

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

import arrow.core.leftIor
import arrow.core.unalign

fun main(args: Array<String>) {
  //sampleStart
  val result = sequenceOf(1, 2, 3).unalign { it.leftIor() }
  //sampleEnd
  println("(${result.first.toList()}, ${result.second.toList()})")
}
