ASHPD, acronym of Aperture Science Handheld Portal Device is a Rust & zbus wrapper of the XDG portals DBus interfaces. The library aims to provide an easy way to interact with the various portals defined per the specifications. It provides an alternative to the C library https://github.com/flatpak/libportal

Ask the compositor to pick a color

use ashpd::desktop::Color;

async fn run() -> ashpd::Result<()> {
    let color = Color::pick().send().await?.response()?;
    println!("({}, {}, {})", color.red(), color.green(), color.blue());
    Ok(())
}

Start a PipeWire stream from the user's camera

use ashpd::desktop::camera::Camera;

pub async fn run() -> ashpd::Result<()> {
    let camera = Camera::new().await?;
    if camera.is_present().await? {
        camera.request_access().await?;
        let remote_fd = camera.open_pipe_wire_remote().await?;
        // pass the remote fd to GStreamer for example
    }
    Ok(())
}

The library comes with a demo built using the GTK 4 Rust bindings and previews most of the portals. It is meant as a test case for the portals (from a distributor perspective) and as a way for the developers to see which portals exists and how to integrate them into their application using ASHPD.

The library also comes with a backend demo that exemplifies how to implement a portal backend.
