The minimal interface a chess engine must provide.

Required Methods

fn current_mapping(&self) -> &PieceMapping

Get the current PieceMapping (which piece sits on which square).

fn current_occupied(&self) -> Occupied

Get the current occupancy bitboard.

fn current_captured_bits(&self) -> CapturedBits

Get the current captured‐bits mask.

fn side_to_move(&self) -> Color

Return side to move: White or Black.

fn en_passant_target(&self) -> Option<u8>

Return the current en_passant_target if any.

fn ply(&self) -> usize

Return the number of plies played so far (0..=128).

fn game_result(&self) -> GameResult

Return GameResult (Checkmate/Stalemate/Ongoing).

fn read_ply(&self, i: usize) -> Move10

Return the Move10 code stored at ply index i (0..ply−1).

fn generate_pseudo_legal_moves(&self) -> Vec<Move10>

Generate all pseudo‐legal moves (Move10) for side_to_move, ignoring self‐check.

fn push_move(&mut self, mv: Move10) -> Result<(), MoveError>

Push a move onto the stack. Returns Ok(()) if move is legal and does not leave king in check. Otherwise returns Err(MoveError).

fn pop_move(&mut self)

Pop (undo) the last half‐move, if any.

fn reset(&mut self)

Reset to the starting position (also clears all bit‐planes).
