Description:
TH-generated EnumSet/EnumMap wrappers around IntSet/IntMap
This package wraps IntSet and IntMap from containers, and provides fast sets and maps keyed on any data type with a well-behaved Enum instance. Useful for derived Enums, newtype'd Ints, or any data type that can be packed into an Int: just implement fromEnum and toEnum. . The boilerplate is generated using Template Haskell, so unlike enummapset it's easier to maintain and keep up-to-date with containers. On the downside, it's less portable. . Note that "Data.EnumMap.Lazy" and "Data.EnumMap.Strict" provide distinct newtype wrappers, and their respective 'Functor' instances behave as expected, unlike that of IntMap which is alway lazy. . This package provides a library for the Haskell programming language. See http://www.haskell.org/ for more information on Haskell.
