Types

data class Const<A, out T>(value: A)

sealed class Either<out A, out B>

In day-to-day programming, it is fairly common to find ourselves writing functions that can fail. For instance, querying a service may result in a connection issue, or some unexpected JSON response.

Endo

data class Endo<A>(val f: (A) -> A)

The monoid of endomorphisms under composition.

Eval

sealed class Eval<out A>

Eval is a monad which controls evaluation of a value or a computation that produces a value.

Invalid

typealias Invalid<E> = Validated.Invalid<E>

Ior

sealed class Ior<out A, out B>

Port of https://github.com/typelevel/cats/blob/v0.9.0/core/src/main/scala/cats/data/Ior.scala

IorNel

typealias IorNel<A, B> = Ior<Nel<A>, B>

Nel

typealias Nel<A> = NonEmptyList<A>

None

object None : Option<Nothing>

NonEmptyList

class NonEmptyList<out A>(val head: A, val tail: List<A>) : AbstractList<A>

NonEmptyList is a data type used in Λrrow to model ordered lists that guarantee to have at least one value. NonEmptyList is available in the arrow-core module under the import arrow.core.NonEmptyList

Nullable

object Nullable

Option

sealed class Option<out A>

If you have worked with Java at all in the past, it is very likely that you have come across a NullPointerException at some time (other languages will throw similarly named errors in such a case). Usually this happens because some method returns null when you weren't expecting it and, thus, isn't dealing with that possibility in your client code. A value of null is often abused to represent an absent optional value. Kotlin tries to solve the problem by getting rid of null values altogether, and providing its own special syntax Null-safety machinery based on ?.
