I just fixed some weird copy/paste issues when trying to copy text using certain commands in my terminal on arch using Wayland, maybe this can help someone else out.

I'm using arch btw, with KDE and wayland. Posting this incase anyone else is having similar problems.

Some commands that relied on wl-copy like `pass -c` would return empty pastes.

My guess is that the xdg-mime query (from xdg-utils) returns empty output on KDE, and that wl-copy relies on this to determine the MIME type of piped data, and when it gets nothing back, the clipboard MIME type is corrupted.

The fix was replacing wl-clipboard with wl-clipboard-rs which is a rust re-implementation of wl-copy/wl-paste that doesn't depend on xdg-mime for MIME detection.
