Struct Generator 

pub struct Generator { /* private fields */ }

Chess moves generator. Can generate attacks (BitBoard) and Moves for all Chess pieces. Queen does not have it’s own generator, rather is considered both Rook and Bishop.

Examples

Generate all legal moves for a board

use chessgen::{ChessBoard, Generator, Move};

let mut board = ChessBoard::from_string("
      a b c d e f g h
    8 r n b q k b n r 8
    7 p p p p p p p p 7
    6 - - - - - - - - 6
    5 - - - - - - - - 5
    4 - - - - - - - - 4
    3 - - - - - - - - 3
    2 P P P P P P P P 2
    1 R N B Q K B N R 1
      a b c d e f g h
").unwrap();

let moves = board.legal_moves();
assert_eq!(moves.len(), 20);

board = board.validate_and_apply_move(&Move::from_string("b1c3").unwrap()).unwrap();

assert_eq!(
    board.pieces,
    ChessBoard::from_string("
      a b c d e f g h
    8 r n b q k b n r 8
    7 p p p p p p p p 7
    6 - - - - - - - - 6
    5 - - - - - - - - 5
    4 - - - - - - - - 4
    3 - - N - - - - - 3
    2 P P P P P P P P 2
    1 R - B Q K B N R 1
      a b c d e f g h
    ").unwrap().pieces
);

assert!(board.validate_and_apply_move(&Move::from_string("a1a8").unwrap()).is_err());
