Scalaz: Type classes and pure functional data structures for Scala.
Scalaz: Type classes and pure functional data structures for Scala.
This package, scalaz, contains:
- type class definitions
- data structures
- related functions
Type class instances and other functions related to the Scala and Java standard library are in scalaz.std
Implicit conversions and wrapper classes that provide a more convenient syntax for accessing the functionality of the library are in scalaz.syntax.

Data Structures Index
- scalaz.Validation Represent computations that may succeed or fail, accumulating multiple errors.
- scalaz.NonEmptyList A list containing at least one element.
- scalaz.DList A difference list, supporting efficient append and prepend.
- scalaz.EphemeralStream A stream that holds weak references to its elements, and recomputes them if needed if reclaimed by the garbage collector.
- scalaz.Heap A priority queue, implemented with bootstrapped skew binomial heaps.
- scalaz.Endo Represents functions from A => A.
- scalaz.FingerTree A tree containing elements at it's leaves, and measures at the nodes. Can be adapted to various purposes by choosing a different measure, for example scalaz.IndSeq and scalaz.OrdSeq.
- scalaz.Lens Composable, functional alternative to getters and setters
- scalaz.Tree A multiway tree. Each node contains a single element, and a Stream of sub-trees.
- scalaz.TreeLoc A cursor over a scalaz.Tree.
- scalaz.Zipper A functional cursor over a List.
- scalaz.Kleisli Represents a function A => M[B], allowing chaining. Also known, and aliased, as scalaz.ReaderT.
- scalaz.StateT Computations that modify state.
- scalaz.WriterT Computations that log a value
- scalaz.OptionT Represents computations of type F[Option[A]]
- scalaz.MaybeT Represents computations of type F[Maybe[A]]
- scalaz.EitherT Represents computations of type F[A \/ B]
