bitwise: fast multi-dimensional unboxed bit packed Bool arrays

[ bit-vectors, bsd3, data, data-structures, library ] [ Propose Tags ]

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:
