Rust Life Search, or rlifesrc, is a Game of Life pattern searcher written in Rust.
The program is based on David Bell's lifesrc and Jason Summers's WinLifeSearch, using an algorithm invented by Dean Hickerson.
Compared to WinLifeSearch, rlifesrc is still slower, and lacks many important features. But it supports non-totalistic Life-like and Generations rules.
There is a command-line tool with a TUI and a web app using WebAssembly. The implementation of the algorithm itself is in the lib/ folder.
You can try the web app here.
