Implementations

impl Board

pub fn horde() -> Self

Create the default board for the Horde variant

pub fn empty() -> Self

pub fn rating_bar(&self, len: usize) -> String

pub fn get_turn_color(&self) -> Color

Get the color of the current player

pub fn get_en_passant(&self) -> Option<Position>

Get the position of the En-Passant square

pub fn remove_all(&self, color: Color) -> Self

Remove all of the pieces for a given player

pub fn queen_all(&self, color: Color) -> Self

Convert all of a given players pieces to queens

pub fn set_turn(&self, color: Color) -> Self

Make the game a certain player’s turn

pub fn get_material_advantage(&self, color: Color) -> i32

Get the value of the material advantage of a certain player

pub fn get_piece(&self, pos: Position) -> Option<Piece>

Does a square have any piece?

pub fn has_ally_piece(&self, pos: Position, ally_color: Color) -> bool

Does a square have an ally piece?

pub fn has_enemy_piece(&self, pos: Position, ally_color: Color) -> bool

If a square at a given position has an enemy piece from a given ally color, return true. Otherwise, return false.

For example, if a square has a black piece, and this method is called upon it with an ally_color of Color::White, then it will return true. If called with Color::Black upon the same square, however, it will return false.

pub fn has_piece(&self, pos: Position) -> bool

If a square at a given position has any piece, return true. Otherwise, return false.

pub fn has_no_piece(&self, pos: Position) -> bool

If a square at a given position has no piece, return true. Otherwise, return false.

pub fn get_king_pos(&self, color: Color) -> Option<Position>

If there is a king on the board, return the position that it sits on.

pub fn is_threatened(&self, pos: Position, ally_color: Color) -> bool

Is a square threatened by an enemy piece?

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

Get whether or not the king of a given color is in check.

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

Can a given player castle kingside?

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

Can a given player castle queenside?

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

Does the respective player have sufficient material?

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

Does the respective player have insufficient material?

pub fn is_stalemate(&self) -> bool

Is the current player in stalemate?

pub fn is_checkmate(&self) -> bool

Is the current player in checkmate?

pub fn change_turn(self) -> Self

Change the current turn to the next player.

pub fn play_move(&self, m: Move) -> GameResult

Play a move and confirm it is legal.

Trait Implementations

impl Clone for Board

fn clone(&self) -> Board

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Board

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

Formats the value using the given formatter.

impl Default for Board

fn default() -> Self

Returns the “default value” for a type.

impl Display for Board

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

Formats the value using the given formatter.

impl Evaluate for Board

fn value_for(&self, ally_color: Color) -> f64

Get the value of the board for a given color. This subtracts the opponents value, and accounts for piece positions and material value.

fn get_current_player_color(&self) -> Color

Get the current player’s color.

fn apply_eval_move(&self, m: Move) -> Self

Apply a move to the board for evaluation.

fn get_legal_moves(&self) -> Vec<Move>

Get the legal moves for the current player.

fn get_best_next_move(&self, depth: i32) -> (Move, u64, f64)

Get the best move for the current player with depth number of moves of lookahead.

fn get_worst_next_move(&self, depth: i32) -> (Move, u64, f64)

Get the best move for the current player with depth number of moves of lookahead.

fn minimax(
    &self,
    depth: i32,
    alpha: f64,
    beta: f64,
    is_maximizing: bool,
    getting_move_for: Color,
    board_count: &mut u64
) -> f64

Perform minimax on a certain position, and get the minimum or maximum value for a board. To get the best move, you minimize the values of the possible outcomes from your own position, and maximize the values of the replies made by the other player.

impl From<Board> for BoardBuilder

fn from(board: Board) -> Self

Performs the conversion.

impl Ord for Board

fn cmp(&self, other: &Board) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<Board> for Board

fn eq(&self, other: &Board) -> bool

This method tests for self and other values to be equal, and is used by ==.

This method tests for !=.

impl PartialOrd<Board> for Board

fn partial_cmp(&self, other: &Board) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.
