  9. module Data.Interned.IntSet

    An efficient implementation of integer sets. Since many function names (but not the type name) clash with Prelude names, this module is usually imported qualified, e.g.

    import Data.IntSet (IntSet)
    import qualified Data.IntSet as IntSet
    
    The implementation is based on big-endian patricia trees. This data structure performs especially well on binary operations like union and intersection. However, my benchmarks show that it is also (much) faster on insertions and deletions when compared to a generic size-balanced set implementation (see Data.Set).

    Many operations have a worst-case complexity of O(min(n,W)). This means that the operation can become linear in the number of elements with a maximum of W -- the number of bits in an Int (32 or 64). Unlike the reference implementation in Data.IntSet, Data.Interned.IntSet uses hash consing to ensure that there is only ever one copy of any given IntSet in memory. This is enabled by the normal form of the PATRICIA trie. This can mean a drastic reduction in the memory footprint of a program in exchange for much more costly set manipulation.

  10. data IntSet

    intern Data.Interned.IntSet
