rust chess

features

highly compact bitboard representations
zobrist hashing
magic attack tables
move generation & validation
outcome evaluation (checkmate, stalemate, repetition, insufficient material)
fen parsing
immutable
hella docs
really really really fast (relatively)

i only support standard chess. it is unlikely i will support other variants.

probably check out shakmaty if you want more features

quickstart

[!CAUTION] this is library is still at version 0.0.X

it is very likely that there will be breaking api changes until version 0.1.0

if you use this library, make sure you pin the version in cargo.toml

cargo add ruchess

or in your cargo.toml

[dependencies]
ruchess = "0.0.4"

use ruchess::game::Game;
use ruchess::square;

// Play 1.e4 from the standard starting position.
let game = Game::new();
let after_e4 = game.mve(square::E2, square::E4).unwrap();
assert!(after_e4.position().board().is_occupied(square::E4));

see: docs for more details

see: examples or ruchess tui for example applications

dependencies

just lazy_static

i could probably get rid of it with some refactoring but i am lazy

roadmap

benchmarks
- will move to mutable api if benchmarks are very bad
fen parsing
real uci support
finalise public api
