Trait shakmaty::zobrist::ZobristHash

pub trait ZobristHash {
    fn zobrist_hash<V: ZobristValue>(&self) -> V;

    fn prepare_incremental_zobrist_hash<V: ZobristValue>(
        &self,

}

Supports Zobrist hashing.

Required methods

fn zobrist_hash<V: ZobristValue>(&self) -> V

Computes the Zobrist hash from scratch.

Provided methods

fn prepare_incremental_zobrist_hash<V: ZobristValue>(
    &self,
    _previous: V,
    _m: &Move
) -> Option<V>

Prepares an incremental update of the Zobrist hash before playing move m in self. Returns a new intermediate Zobrist hash, or None if incremental updating is not supported.

fn finalize_incremental_zobrist_hash<V: ZobristValue>(
    &self,
    _intermediate: V,
    _m: &Move
) -> Option<V>

Finalizes an incremental update of the Zobrist hash after playing move m in self. Returns the new Zobrist hash, or None if incremental updating is not supported.
