rchess

A Chess Library Written in Rust

rchess is a Rust-based library designed for applications that need to work with chess games or boards, such as UCI GUIs or online chess platforms.

If you encounter any bugs, have suggestions for improving code readability or performance, or would like to contribute, we encourage you to create a pull request. For significant API changes or feature requests, please open an issue on GitHub.

Getting Started

Documentation for rchess can be found here.

Installation

Add the following to your Cargo.toml:

[dependencies]
rchess = "2.2.0"

Usage Example

use rchess::ChessGame;

fn main() {
    // Create a new chess game.
    let mut game = ChessGame::new();
    
    // Get the legal moves for the current position.
    let moves = game.moves();
    
    // Make a move.
    game.make_move(moves[0]);
}

Features

By default, no features are enabled.

To use magic bitboards for sliding piece move generation, enable the magic-table feature. On my device, this feature speeds up the benches by around 18%.

Build times will be faster without the magic-table feature enabled.

Improving Build Time

To improve the slow build time when the magic-table is enabled, set your build override opt-level to 3.

[profile.dev.build-override]
opt-level = 3

[profile.test.build-override]
opt-level = 3

[profile.release.build-override]
opt-level = 3
