pub struct Board {
    pub pieces: PiecesPlacement,

    pub castling_rights: CastlingRights,
    pub enpassant_file: usize,
    pub occupied: Bitboard,
}

Holds a chess position.

Fields

pieces: PiecesPlacement

The placement of the pieces on the board.

to_move: Color

The side to move.

castling_rights: CastlingRights

The castling rights for both players.

enpassant_file: usize

If the previous move was a double pawn push, contains pushed pawn's file (a value between 0 and 7). Otherwise contains 8.

occupied: Bitboard

The set of all occupied squares on the board.

Always equals self.pieces.color[WHITE] | self.pieces.color[BLACK]. Deserves a field on its own because it is very frequently needed.
