combine

fun <E, T> combine(first: KResult<E, T>, second: KResult<E, T>, combineFailure: (E, E) -> E, combineSuccess: (T, T) -> T): KResult<E, T>(source)

Combine two KResult instances of same type

This is an alternative syntax for calling KResult.combine on the first result and applying second as a parameter.

import io.kresult.core.KResult

fun test() {
  val first: KResult<String, String> = KResult.Success("test 1")
  val second: KResult<String, String> = KResult.Success("test 2")

  KResult.combine(
    first,
    second,
    { f1, f2 -> "$f1, $f2" },
    { s1, s2 -> "$s1, $s2" }
  )
}
