Expand description
Zobrist hashing for positions.
Stability
The Zobrist hash for each position is guaranteed to be stable. Changing hash values is considered a semver breaking change and will be noted in the changelog.
Warning: Forged collisions
Zobrist hashes have good collision resistance, but can be forged efficiently.
Additionally, in this implementation, impossible positions with more than standard material in Crazyhouse pockets are particularly prone to collisions.
Examples
use shakmaty::{Chess, EnPassantMode, zobrist::{Zobrist64, ZobristHash}};
let pos = Chess::default();
assert_eq!(pos.zobrist_hash::<Zobrist64>(EnPassantMode::Legal), Zobrist64(0x463b96181691fc9c));Structs
