wl-data-control-protocol-evt 1.0.0

wl-data-control-protocol-evt

Implementation of ext-data-control Wayland protocol that is:

1. pollable
2. event based

API

Full examples can be found in poll.rs and tokio.rs.

Here's a quick poll-based API overview:

use wl_data_control_protocol_evt::{ExtDataControlEvent, ExtDataControlStream};

let mut stream = ExtDataControlStream::new().unwrap();
let fd = stream.as_fd();

loop {
    poll([fd], IN)?;

    // read
    let events = stream.drain()?;
    for event in events {
        if let ExtDataControlEvent::Received(text) = event {
            println!("copied {text}")
        }
    }

    // or write
    stream.offer_text("try pasting this").unwrap()
}

For async IO you can use something like AsyncFd:

let stream = ExtDataControlStream::new()?;
let async_fd = AsyncFd::new(stream.as_raw_fd())?;

loop {
    let mut guard = async_fd.readable().await?;
    let events = stream.drain()?;
    guard.clear_ready();

    // process `events`
}
