I am working on a GUI library in Rust, aiming at making it backend-independent. So, my library defines abstract events, to be filled by the backend-specific data. For the scan code, I found the scancode crate, based on libSDL2, itself based on the USB HID standard. This seems a good way to encode scan codes, but unfortunately the scancode crate seems unmaintained, and I saw that winit currently uses a u32 for the scan code.

So I'm wondering whether there is interest to:

• use semantic scancode matching the USB HID standard, possibly based on the scancode crate,
• move this and the VirtualKeyCode struct into their own crate as part of rust-windowing.
