Trait Implementations

impl Position for VariantPosition

fn legal_moves(&self, moves: &mut MoveList)

Collects all legal moves in an existing buffer.

fn san_candidates(&self, role: Role, to: Square, moves: &mut MoveList)

Generates a subset of legal moves: All piece moves and drops of type role to the square to, excluding castling moves.

fn castling_moves(&self, side: CastlingSide, moves: &mut MoveList)

Generates legal castling moves.

fn en_passant_moves(&self, moves: &mut MoveList)

Generates en passant moves.

fn capture_moves(&self, moves: &mut MoveList)

Generates capture moves.

fn promotion_moves(&self, moves: &mut MoveList)

Generate promotion moves.

fn is_irreversible(&self, m: &Move) -> bool

Tests if a move is irreversible.

fn king_attackers(
    &self,
    square: Square,
    attacker: Color,
    occupied: Bitboard
) -> Bitboard

Attacks that a king on square would have to deal with.

fn castles(&self) -> &Castles

Castling paths and unmoved rooks.

fn checkers(&self) -> Bitboard

Bitboard of pieces giving check.

fn is_variant_end(&self) -> bool

Checks if the game is over due to a special variant end condition.

fn has_insufficient_material(&self, color: Color) -> bool

Tests if a side has insufficient winning material.

fn variant_outcome(&self) -> Option<Outcome>

Tests special variant winning, losing and drawing conditions.

fn play_unchecked(&mut self, m: &Move)

Plays a move. It is the callers responsibility to ensure the move is legal.

fn swap_turn(self) -> Result<Self, PositionError> where
    Self: Sized + FromSetup, 

Swap turns. This is sometimes called "playing a null move".

fn legals(&self) -> MoveList

Generates legal moves.

fn is_legal(&self, m: &Move) -> bool

Tests a move for legality.

fn is_check(&self) -> bool

Tests if the king is in check.

fn is_checkmate(&self) -> bool

Tests for checkmate.

fn is_stalemate(&self) -> bool

Tests for stalemate.

fn is_insufficient_material(&self) -> bool

Tests if both sides have insufficient winning material.

fn is_game_over(&self) -> bool

Tests if the game is over due to checkmate, stalemate, insufficient material or variant end.

fn outcome(&self) -> Option<Outcome>

The outcome of the game, or None if the game is not over.

fn play(self, m: &Move) -> Result<Self, IllegalMoveError> where
    Self: Sized, 

Plays a move.
