kadiraltuntas/rust-external-cheat — reverse-engineered prompt

I found this repo called rust external cheat, but the README is basically just ranting and does not explain anything useful.

Please inspect the code in the driver and external app folders, figure out what is actually here, clean up any broken pasted code, and turn it into a harmless educational sample that compiles and is easy to understand. I want clear comments, a rewritten README in plain language, and a simple way to build and run whatever parts are safe to demonstrate locally. If anything looks sketchy or not appropriate, replace it with mock behavior and explain what it was supposed to do instead. Look up current docs online if you need to.
