copypasta is a rust-clipboard fork, adding support for the Wayland clipboard.

rust-clipboard is a cross-platform library for getting and setting the contents of the OS-level clipboard.

extern crate copypasta;

use copypasta::ClipboardContext;

fn example() {
    let mut ctx = ClipboardContext::new().unwrap();
    println!("{:?}", ctx.get_contents());
    ctx.set_contents("some string".to_owned()).unwrap();
}

The ClipboardProvider trait has the following functions:

fn get_contents(&mut self) -> Result<String, Box<Error>>;
fn set_contents(&mut self, String) -> Result<(), Box<Error>>;

ClipboardContext is a type alias for one of {WindowsClipboardContext, OSXClipboardContext, X11ClipboardContext, NopClipboardContext}, all of which implement ClipboardProvider. Which concrete type is chosen for ClipboardContext depends on the OS (via conditional compilation).
