toByteString :: Ix i => BitArray i -> ByteString
bitwise Data.Array.BitArray.ByteString

toByteStringIO :: Ix i => IOBitArray i -> IO ByteString
bitwise Data.Array.BitArray.ByteString
Copy to a ByteString. The most significant bits of the last byte are padded with 0 unless the array was a multiple of 8 bits in size.
