  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]
