Rusty Rival

A UCI chess engine written in Rust. Please take a look at the UCI Documentation for usage instructions.

Binaries for Windows, Mac OS and Linux are available on the releases page.

The engine can be about 50% faster if compiled on the machine on which it will be run in order to take advantage of cpu-specific instructions. To compile locally, it requires that Rust be installed.

RUSTFLAGS="-C target-cpu=native" RUST_MIN_STACK=4097152 cargo run --release
