[−][src]Crate chess

Rust Chess Library

This is a chess move generation library for rust. It is designed to be fast, so that it can be used in a chess engine or UI without performance issues.

Example

This generates all the moves on the starting chess position, and checks that the number of moves is correct.


use chess::{Board, MoveGen};

let board = Board::default();
let movegen = MoveGen::new_legal(&board);
assert_eq!(movegen.len(), 20);

Structs

BitBoard	A good old-fashioned bitboard You do have access to the actual value, but you are probably better off using the implemented operators to work with this object.
Board	A representation of a chess board. That's why you're here, right?
BoardBuilder	Represents a chess position that has not been validated for legality.
CacheTable	Store a cache of entries, each with an associated hash.
ChessMove	Represent a ChessMove in memory
Game	For UI/UCI Servers, store a game object which allows you to determine draw by 3 fold repitition, draw offers, resignations, and moves.
MoveGen	An incremental move generator
Square	Represent a square on the chess board

Enums

Action	Contains all actions supported within the game
BoardStatus	What is the status of this game?
CastleRights	What castle rights does a particular player have?
Color	Represent a color.
Error	Sometimes, bad stuff happens.
File	Describe a file (column) on a chess board
GameResult	What was the result of this game?
Piece	Represent a chess piece as a very simple enum
Rank	Describe a rank (row) on a chess board

Constants

ALL_CASTLE_RIGHTS	Enumerate all castle rights.
ALL_COLORS	List all colors
ALL_FILES	Enumerate all files
ALL_PIECES	An array representing each piece type, in order of ascending value.
ALL_RANKS	Enumerate all ranks
ALL_SQUARES	A list of every square on the chessboard.
EDGES	What are all the edge squares on the `BitBoard`?
EMPTY	An empty bitboard. It is sometimes useful to use !EMPTY to get the universe of squares.
NUM_CASTLE_RIGHTS	How many different types of `CastleRights` are there?
NUM_COLORS	How many colors are there?
NUM_FILES	How many files are there?
NUM_PIECES	How many piece types are there?
NUM_PROMOTION_PIECES	How many ways can I promote?
NUM_RANKS	How many ranks are there?
NUM_SQUARES	How many squares are there?
PROMOTION_PIECES	What pieces can I promote to?

Functions

between	Get a line between these two squares, not including the squares themselves.
construct	This is now a no-op. It does not need to be called anymore.
get_adjacent_files	Get a `BitBoard` that represents the squares on the 1 or 2 files next to this file.
get_bishop_moves	Get the moves for a bishop on a particular square, given blockers blocking my movement.
get_bishop_rays	Get the rays for a bishop on a particular square.
get_file	Get a `BitBoard` that represents all the squares on a particular file.
get_king_moves	Get the king moves for a particular square.
get_knight_moves	Get the knight moves for a particular square.
get_pawn_attacks	Get the pawn capture move for a particular square, given the pawn's color and the potential victims
get_pawn_moves	Get all the pawn moves for a particular square, given the pawn's color and the potential blocking pieces and victims.
get_pawn_quiets	Get the quiet pawn moves (non-captures) for a particular square, given the pawn's color and the potential blocking pieces.
get_rank	Get a `BitBoard` that represents all the squares on a particular rank.
get_rook_moves	Get the moves for a rook on a particular square, given blockers blocking my movement.
get_rook_rays	Get the rays for a rook on a particular square.
line	Get a line (extending to infinity, which in chess is 8 squares), given two squares. This line does extend past the squares.
