Implementations

impl Castles

pub const fn new() -> Castles

impl Castles

pub const fn empty(mode: CastlingMode) -> Castles

pub fn from_setup(setup: &Setup, mode: CastlingMode) -> Result<Castles, Castles>

pub const fn any(&self) -> bool

pub const fn is_empty(&self) -> bool

pub fn has(&self, color: Color, side: CastlingSide) -> bool

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

pub fn discard_rook(&mut self, square: Square)

pub fn discard_color(&mut self, color: Color)

pub const fn rook(&self, color: Color, side: CastlingSide) -> Option<Square>

pub const fn path(&self, color: Color, side: CastlingSide) -> Bitboard

Gets the squares that need to be empty so that castling is possible on the given side, assuming the player still has the required castling rigths.

Examples

use shakmaty::{Castles, CastlingSide, Bitboard, Color, Square};

let castles = Castles::default();
let path = castles.path(Color::White, CastlingSide::QueenSide);
