Hey i was looking around found out:
Alacritty has a fork off clipboard called copypasta that supports wayland.
https://github.com/alacritty/copypasta
Then we don't need to change anything than the dep maybe?

Good find. rust-clipboard seems unmaintained as well, I'll give the fork a shot.

I tried it. The API has change a little bit, but it works perfekt on Sway.

Tried it as well, and so far no luck 🤔

Ohh Yeah I forgot about it, I also had problems copy paste with alacritty.

This should not be the work around I think, I forgot I installed it.

Yeah it definitely requires more work than just adapting the API (although updating the dep is still a good thing, I'll make a PR for that anyhow).

We need to give the clipboard a pointer to the Wayland display.

    #[cfg(all(feature = "wayland", not(any(target_os = "macos", windows))))]
    pub unsafe fn new(display: Option<*mut c_void>) -> Self {
        match display {
            Some(display) => {
                let (selection, clipboard) =
                    wayland_clipboard::create_clipboards_from_external(display);
                Self { clipboard: Box::new(clipboard), selection: Some(Box::new(selection)) }
            },
            None => Self::default(),
        }
    }

Not sure if we can do it this way through winit
