bytestring-0.9.2.1: Fast, packed, strict and lazy byte arrays with a list interface

A time and space-efficient implementation of byte vectors using packed Word8 arrays, suitable for high performance use, both in terms of large data quantities, or high speed requirements. Byte vectors are encoded as strict Word8 arrays of bytes, and lazy lists of strict chunks, held in a ForeignPtr, and can be passed between C and Haskell with little effort.

Test coverage data for this library is available at: http://code.haskell.org/~dons/tests/bytestring/hpc_index.html
