Enum chess_engine::GameResult

pub enum GameResult {
    Continuing(Board),
    Victory(Color),
    Stalemate,
    IllegalMove(Move),
}

The result of a move being played on the board.

Variants

Continuing(Board)

The game is not finished, and the game is still in play.

Tuple Fields of Continuing

0: Board

Victory(Color)

One player, the victor, checkmated the other. This stores the color of the winner.

Tuple Fields of Victory

0: Color

Stalemate

The game is drawn. This can be a result of the current player having no legal moves and not being in check, or because both players have insufficient material on the board.

Insufficient material consists of:

1. The player only has a king
2. The player only has a king and a knight
3. The player only has a king and two knights
4. The player only has a king and a bishop
5. The player only has a king and two bishops

In a regular game of chess, threefold repetition also triggers a stalemate, but this engine does not have builtin support for threefold repetition detection yet.

IllegalMove(Move)

An illegal move was made. This can include many things, such as moving a piece through another piece, attempting to capture an allied piece, moving non-orthogonally or non-diagonally, or non-knight-like according the rules governing the movement of the piece. Additionally, moves that put the player in check, (for example, moving a pinned piece), are also illegal.

Tuple Fields of IllegalMove

0: Move

Trait Implementations

impl Clone for GameResult

fn clone(&self) -> GameResult

Returns a copy of the value.

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