chess 0.4.1

This is a fast chess move generator. It has a very good set of documentation, so you should take advantage of that. It (now) generates all lookup tabels with a build.rs file, which means that very little pseudo-legal move generation requires branching. There are some convenience functions that are exposed to, for example, find all the squares between two squares. This uses a copy-on-make style structure, and the Board structure is as slimmed down as possible to reduce the cost of copying the board. There are places to improve perft-test performance further, but I instead opt to be more feature-complete to make it useful in real applications. For example, I generate both a hash of the board and a pawn-hash of the board for use in evaluation lookup tables (using Zobrist hashing). There are two ways to generate moves, one is faster, the other has more features that will be useful if making a chess engine. See the documentation for more details.

A Fast Chess Library In Rust

This library handles the process of move generation within a chess engine or chess UI.

This library is still a work in progress, but, it does work well. Expect API changes. I'm hoping to get this into a stable state for release relatively soon.

What It Does

This library allows you to create a chess board from a FEN-formatted string, list all legal moves for the chess board and make moves.

This library also allows you to view various pieces of board-state information such as castle rights.

This library has very fast move generation (the primary purposes of its existance), which will be optimized more. All the tricks to make chess move generation fast are used.

What It Does Not Do

This is not a chess engine, just the move generator. This is not a chess UI, just the move generator. This is not a chess PGN parser, database, UCI communicator, XBOARD/WinBoard protocol, website or grandmaster. Just a humble move generator.

Anything Else

Nope. Have fun.
