Name:                bitwise
Version:             0.1.0.1
Synopsis:            fast multi-dimensional unboxed bit packed Bool arrays
Description:
  Unboxed multidimensional bit packed Bool arrays with fast aggregate
  operations based on lifting Bool operations to bitwise operations.
  .
  There are many other bit packed structures out there, but none met
  all of these requirements:
  .
    (1) unboxed bit packed Bool array,
  .
    (2) multi-dimensional indexing,
  .
    (3) fast (de)serialization, or interoperable with foreign code,
  .
    (4) fast aggregate operations (fold, map, zip).
  .
  Quick tour of the bitwise library:
  .
  [Data.Bits.Bitwise] Lift boolean operations on 'Bool' to bitwise
  operations on 'Data.Bits.Bits'.
  .
  [Data.Array.BitArray] Immutable bit arrays.
  .
  [Data.Array.BitArray.ST] Mutable bit arrays in 'Control.Monad.ST.ST'.
  .
  [Data.Array.BitArray.IO] Mutable bit arrays in 'IO'.
  .
  [Data.Array.BitArray.ByteString] (De)serialization.
  .
  [Codec.Image.PBM] Portable bitmap monochrome 2D image format.
  .
  Very rough performance benchmarks:
  .
    * immutable random access single bit reads:
      @BitArray ix@ is about 40% slower than @UArray ix Bool@,
  .
    * 'Control.Monad.ST.ST' mutable random access single bit reads:
      @STBitArray s ix@ is about the same as @STUArray s ix Bool@,
  .
    * immutable map @Bool -> Bool@:
      @BitArray ix@ is about 85x faster than @UArray ix Bool@,
  .
    * immutable zipWith @Bool -> Bool -> Bool@:
      @BitArray ix@ is about 1300x faster than @UArray ix Bool@.
