A pure-Rust keylogger for Windows, attaching to the raw keyboard events. No dependencies other
than user32.lib being available on the system, which it probably is if you can compile Rust.
This code is likely to be a good base to also log mouse or other HID events, and even simulate them or replay them. The goal of the project is to investigate the raw events produced.
The code follows the guide Minimal Key Logger Using RAWINPUT written by Mike G. P.Mee, where the implementation itself is pretty much borrowed from Microsoft's Using Raw Input.
Another interesting project is aquatone's ProjectEagleWatch, written in C, which seems to be more wary about hiding itself, though I have not tried it.
