This is a compile-time sized bitset implementation that supports bitwise implementations, including shifts.
I built this to address a specific use-case that no other crate at the time could support.
Specifically I use this in my battlesnake AI shapeshifter as the underlying datastructure for the bitboard representation of the game board. For this I needed the bitset to be of arbitrary (but known at compile-time) size, so I can build boards of different sizes and work with them without allocating heap memory. I also needed fast bitwise operations, Specifically including bit shifts.
This crate has proven itself production in the sense that it powers one of the strongest multiplayer snake AIs in the world. I still would advise against using it in other contexts, because it ditches some common sense sanity checks around out of bounds access, which you would probably want to have in most other use-cases.
