parTupled

inline suspend fun <A, B> parTupled(context: CoroutineContext = EmptyCoroutineContext, crossinline fa: suspend CoroutineScope.() -> A, crossinline fb: suspend CoroutineScope.() -> B): Pair<A, B>

Runs fa, fb in parallel on ctx and combines their results as a tuple.

Coroutine context is inherited from caller, additional context elements can be specified with context argument. If the context does not have any dispatcher nor any other ContinuationInterceptor, then Dispatchers.Default is used.

import arrow.fx.coroutines.*
import kotlinx.coroutines.Dispatchers

suspend fun main(): Unit {
  //sampleStart
  val result = parTupled(
    Dispatchers.IO,
    { "First one is on ${Thread.currentThread().name}" },
    { "Second one is on ${Thread.currentThread().name}" }
  )
  //sampleEnd
 println(result)
}
