Rust Chess Engine

A simple chess engine written in Rust, implementing a Negamax search algorithm.
Currently supports move generation and evaluation, with a basic Negamax search. Alpha-beta pruning and more are planned for future improvements.

Build and Run

Engine is now in the middle of major refactoring before its first release! Its not complete, building running is not recomended.
