Struct alcibiades::stock::StdMoveGenerator

pub struct StdMoveGenerator<T: Evaluator> { /* fields omitted */ }

Implements the MoveGenerator trait.

Trait Implementations

impl<T: Clone + Evaluator> Clone for StdMoveGenerator<T>

fn clone(&self) -> StdMoveGenerator<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Evaluator> MoveGenerator for StdMoveGenerator<T>

type Evaluator = T

The type of static evaluator that the implementation works with.

fn from_board(board: Board) -> Result<Self, IllegalBoard>

Creates a new instance, consuming the supplied Board instance.

fn hash(&self) -> u64

Returns the Zobrist hash value for the underlying Board instance.

fn board(&self) -> &Board

Returns a reference to the underlying Board instance.

fn attacks_to(&self, square: Square) -> Bitboard

Returns a bitboard with all pieces that attack square.

fn checkers(&self) -> Bitboard

Returns a bitboard with all enemy pieces that attack the king.

fn evaluator(&self) -> &Self::Evaluator

Returns a reference to a static evaluator bound to the current position.

fn generate_all<U: AddMove>(&self, moves: &mut U)

Generates all legal moves, possibly including some pseudo-legal moves too.

The moves are added to moves. All generated moves with pieces other than the king will be legal. Some of the generated king's moves may be illegal because the destination square is under attack.

The initial move score for all generated moves is 0.

Note: A pseudo-legal move is a move that is otherwise legal, except it might leave the king in check.

fn generate_forcing<U: AddMove>(&self, generate_checks: bool, moves: &mut U)

Generates moves for the quiescence search.

The moves are added to moves. This method always generates a subset of the moves generated by generate_all:

• If the king is in check, all legal moves are included.

• Captures and pawn promotions to queen are always included.

• If generate_checks is true, moves that give check are included too. Discovered checks and checks given by castling are omitted for speed.

fn try_move_digest(&self, move_digest: MoveDigest) -> Option<Move>

Checks if move_digest represents a pseudo-legal move.

fn null_move(&self) -> Move

Returns a null move.

fn do_move(&mut self, m: Move) -> Option<u64>

Plays a move on the board.

fn undo_move(&mut self, m: Move)

Takes back last played move.

fn evaluate_move(&self, m: Move) -> Value

Returns the likely evaluation change (material) to be lost or gained as a result of a given move.

impl<T: Evaluator> SetOption for StdMoveGenerator<T>

fn options() -> Vec<(String, OptionDescription)>

Returns a list of supported configuration options (name and description).

fn set_option(name: &str, value: &str)

Sets a new value for a given configuration option.
