Package arrow.meta.continuations

Types

sealed class ContSeq<out A>

ContSeq is multi-shot control-flow streaming type. It can emit 0..n elements, and it has ability to abort processing elements at any given time in the stream without aborting the whole stream.

interface ContSeqSyntax<in A> : ContSyntax

The scope for yielding values of a ContSeq, provides yield and yieldAll suspension functions.

interface ContSyntax

ContSyntax exposes abort which allows for interruption of the computation, meaning that when abort is encountered the Cont will be interrupted and will not yield a value.

Functions

fun <A> Iterable<A>.asContSeq(): ContSeq<A>

Convert any Iterable into a ContSeq

inline fun <A> cont(crossinline f: () -> A): ContSeq<A>

Smart constructor for single-shot ContSeq effect.

inline fun doOnlyWhen(condition: Boolean, crossinline f: () -> ContSeq<Unit>): ContSeq<Unit>

inline fun <A> doOnlyWhen( condition: Boolean, value: A, crossinline f: () -> ContSeq<A>): ContSeq<A>

Execute a side effect only when some condition holds.

doOnlyWhenNotNull

inline fun <T, A> doOnlyWhenNotNull( thing: T?, value: A, crossinline f: (T) -> ContSeq<A>): ContSeq<A>

Execute a side effect only when some condition holds.

fun <A> List<ContSeq<A>>.nested(): ContSeq<List<A>>

fun <A> List<ContSeq<A>>.sequence(): ContSeq<List<A>>
