So consider instead keeping a running score of the position, rather than recalculating it in full every time. One of the main tricks behind Stockfish NNUE, the current top chess engine, is a clever way of not needing to fully recalculate the full neural net every time, but to do a delta update for each move for a substantial part of the network. I forget the main paper about that, but you can read about it in https://github.com/asdfjkl/neural_network_chess.

It was doing integer-typed reads and writes of data that could contain padding. The rules around that used to be unclear, but as of https://github.com/rust-lang/rust/pull/98919 it's definitely not okay to have undefined values of integer type.
