Help me find a perfect hash function and fill a hash table in compile time
If you'd like to reference something, my movegen crate cozy-chess does this. I also have a standalone reference implementation here as part of my magic bitboard article.

Interested in creating, playing and testing your own chess engine?
https://github.com/ShailChoksi/lichess-bot is a straight forward way to use any UCI engine with lichess. There are also a few libraries for move generation mine: https://github.com/Disservin/chess-library , libchess: https://github.com/kz04px/libchess , surge: https://github.com/nkarve/surge . These are C++ ones, for rust theres https://github.com/analog-hors/cozy-chess . In python you could use python-chess but its incredibly slow for engine stuff writing your own will probably be faster if you know what you are doing.

cozy-chess: A Chess and Chess960 move generation library
A while back, I got into computer chess. I used Jordan Bray's neat chess crate for move generation, and was pretty satisfied until I took a look at the code. It's pretty good and all, but... So. Much. unsafe. Out of a mix of frustration and curiosity, I made it my next project to create my own chess move generation library. So... here it is, I guess: https://github.com/analog-hors/cozy-chess/ It's my first crate, so feedback would be appreciated! It's currently being used in my (weak) chess engine Tantabus.

cozy-chess: A Chess and Chess960 move generation library
I think it provides similar performance as chess, though I don't really want to give any hard numbers as apparently the system I benchmark on is not the most reliable for that. Nevertheless, depth 6 kiwipete ("r3k2r/p1ppqpb1/bn2pnp1/3PN3/1p2P3/2N2Q1p/PPPBBPPP/R3K2R w KQkq - 0 1"): chess: Result: 8031647685 Time: 30s 547ms shakmaty: Result: 8031647685 Time: 49s 669ms cozy-chess: Result: 8031647685 Time: 26s 673ms Tested using a modified version of Jordan Bray's chess_perft.

Compile time
Out of curiosity, what causes the initial 100% utilization to drop. I'm new to complied languages, and yesterday I was playing around with this chess move generation library. On my ryzen 1600, I saw the same behaviour. Full utlisation for the first half, then dropped down to about 20-30% utltisation
