parSequence

suspend fun <A> Iterable<suspend () -> A>.~~parSequence~~(): List<A>

Deprecated

Function is being renamed to parMap in 2.x.x

Replace with

import arrow.fx.coroutines.parMap
import kotlinx.coroutines.Dispatchers

parMap(Dispatchers.Default) { it() }

@JvmName(name = "parSequenceScoped")

suspend fun <A> Iterable<suspend CoroutineScope.() -> A>.~~parSequence~~(): List<A>

Deprecated

Function is being renamed to parMap in 2.x.x

Replace with

import arrow.fx.coroutines.parMap
import kotlinx.coroutines.Dispatchers

parMap(Dispatchers.Default) { it() }

Sequences all tasks in parallel on Dispatchers.Default and return the result

Cancelling this operation cancels all running tasks.

Coroutine context is inherited from a CoroutineScope, additional context elements can be specified with ctx argument. If the combined context does not have any dispatcher nor any other ContinuationInterceptor, then Dispatchers.Default is used. WARNING If the combined context has a single threaded ContinuationInterceptor, this function will not run in parallel.
