What's new in Cyclops X (cyclops 10.0.0)


  • Fast purely functional datastructures (Vector, Seq / List, LazySeq / LazyList, NonEmptyList, HashSet, TreeSet, TrieSet, HashMap, LinkedMap, MultiMap, TreeMap, BankersQueue, LazyString, Discrete Interval Encoded Tree, Zipper, Range, Tree, DifferenceList, HList, Dependent Map )
  • Structural Pattern Matching API (deconstruct algebraic product and sum types)
  • Improved type safety via the removal of unsafe APIs -- E.g. Unlike Optional, Option has no get method (which could throw a null pointer) -- New data structures do not support operations that would throw exceptions (you can't call head on an empty list for example)
  • Eager and Lazy alternatives for most datastructures (Option is eager, Maybe is lazy + reactive)
  • Improved naming of types (Function1-8 rather than Fn1-8, Either not Xor)
  • Group id is changed to com.oath.cyclops
  • Versioning between cyclops-react and cyclops is merged on cyclops versioning scheme (version 10 = Cyclops X)
  • Light weight dependencies : reactive-streams API & Agrona
