I am happy to announce the stable release of bitvec- This package provides a "better" Vector instance for Bool.

An unboxed Vector Bool spends 8 bits per boolean, while bitvec provides a newtype Bit and a custom instance of Vector, packing booleans densely and achieving 8x less memory footprint. Performance stays roughly the same, and certain bulk operations become up to 64x faster.


Best regards,
