Collections

KList

KList is a cons-based List. It provides access to head by hd and access to tail by hd. It takes only constant time to insert a new element to front of the KList. Note that it takes linear time to append a new element to last of the KList

KStream

KStream is like a KList seemingly. But it differs from KList in that KStream's tail is lazily evaluated. Therefore, KStream can represent an infinite stream. For example, ones is an infinite stream that consists of only 1 such as the following:

val ones: KStream<Int> = 1 cons { ones }

KOption

KOption is a container which has only one value(Some) or no value(None).

KStack

KStack is cons-based immutable stack implementation.

KListMap

KListMap is KList-based immutable Map.

KListSet

KListMap is KList-based immutable Set.

KTreeSet

KTreeSet is RedBlackTree-based immutable Set.

KTreeMap

KTreeMap is RedBlackTree-based immutable Map.
