impl MutBoardImpl

Implementation of board evolution/devolution via some given Move instance which is assumed to be legal for this board.

pub fn evolve(&mut self, action: &Move) -> Discards

Public API for evolving a board. All that is required is a reference to a move which is assumed to be legal. The information required to reverse this same move is returned and the board is mutated to the next state.

pub fn devolve(&mut self, action: &Move, discards: Discards)

Public API for devolving a move, the information lost at evolve time is required as an input here to recover the lost state exactly.

pub fn compute_moves_impl(
    &mut self,
    computation_type: MoveComputeType
) -> Vec<Move, Global>

Trait Implementations

impl Clone for MutBoardImpl

pub fn clone(&self) -> MutBoardImpl

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MutBoardImpl

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl MutBoard for MutBoardImpl

pub fn evolve(&mut self, action: &Move) -> Discards

Evolves this board in place according to the given move reference. The move must be one that is legal in this position otherwise the results are undefined. The data which is lost during this evolution is returned at the end of the procedure allowing for devolution to take place.

pub fn devolve(&mut self, action: &Move, discards: Discards)

Reverses the given move, i.e. it devolves the board. It can only be called after the same move has been used to evolve the board. The discarded information produced by the evolve call must be provided here. If any of these conditions are not met the results of this procedure are undefined.

pub fn compute_moves(
    &mut self,
    computation_type: MoveComputeType
) -> Vec<Move, Global>

Compute a vector of all the legal moves in this position for the given computation type. Note there is no particular ordering to the move vector.

pub fn termination_status(&mut self) -> Option<Termination>

Compute the termination state of this node. If it is not terminal nothing is returned, if it is then the manner of termination is returned wrapped inside an Option. The termination can be only a draw or a loss since a side only loses when it runs out of moves, i.e. you don't play a winning move, you just fail to have a legal move.

pub fn in_check(&mut self) -> bool

Determines whether the active side is in a state of check.

pub fn side(&self, side: Side) -> BitBoard

Return the locations of all pieces on the given side.

pub fn sides(&self) -> (BitBoard, BitBoard)

Return the locations of all white and black pieces.

pub fn hash(&self) -> u64

Returns the Zobrist hash of this position.

pub fn active(&self) -> Side

Return the active side in this position, i.e. the one whose turn it is.

pub fn enpassant(&self) -> Option<Square>

Return the enpassant target square in this position.

pub fn castle_status(&self, side: Side) -> Option<CastleZone>

Return the castling status of the given side.

pub fn locs(&self, piece: Piece) -> BitBoard

Return the locations of the given piece.

pub fn king(&self, side: Side) -> Square

Return the location of the king for the given side.

pub fn piece(&self, location: Square) -> Option<Piece>

Return the piece occupying the given location.

pub fn half_move_clock(&self) -> usize

Return the half move clock value at this position.

pub fn history_count(&self) -> usize

Return the total number of half moves played to reach this position.

pub fn remaining_rights(&self) -> CastleZoneSet

Return the remaining castling rights from this position.

pub fn to_partial_fen(&self, cmps: &[FenComponent]) -> String

Return the specified components of the FEN encoding of this position in the given order with components separated by a space.

pub fn to_fen(&self) -> String

Return the complete FEN representation of this position.

pub fn multi_locs(&self, pieces: &[Piece]) -> BitBoard

Returns the locations of a set of pieces as a single bitboard.

pub fn all_pieces(&self) -> BitBoard

Returns the locations of all pieces on the board.
