ASHPD

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

Examples

Ask the compositor to pick a color

```rust,no_run use ashpd::desktop::screenshot::ScreenshotProxy; use ashpd::WindowIdentifier;

async fn run() -> ashpd::Result<()> { let connection = zbus::Connection::session().await?; let proxy = ScreenshotProxy::new(&connection).await?;

let color = proxy.pick_color(&WindowIdentifier::default()).await?;
println!("({}, {}, {})", color.red(), color.green(), color.blue());
Ok(())

} ```

Start a PipeWire stream from the user's camera

```rust,no_run use ashpd::desktop::camera::CameraProxy;

pub async fn run() -> ashpd::Result<()> { let connection = zbus::Connection::session().await?; let proxy = CameraProxy::new(&connection).await?;

if proxy.is_camera_present().await? {
    proxy.access_camera().await?;
    let remote_fd = proxy.open_pipe_wire_remote().await?;
    // pass the remote fd to GStreamer for example
}
Ok(())

} ```

Optional features

| Feature | Description | | --- | ----------- | | log | Record various debug information using the tracing library | | featuregtk3 | Implement From<Color> for gdk3::RGBA | | | Provides WindowIdentifier::from_window that takes a IsA<gdk3::Window> | | featuregtk4 | Implement From<Color> for gdk4::RGBA | | | Provides WindowIdentifier::from_native that takes a IsA<gtk4::Native> | | featurepipewire | Provides ashpd::desktop::camera::pipewire_node_id that helps you retrieve the PipeWire Node ID to use with the file descriptor returned by the camera portal | | rawhandle | Provides WindowIdentifier::from_raw_handle and WindowIdentifier::as_raw_handle for raw-window-handle crate | | wayland | Provides WindowIdentifier::from_wayland for wayland-client crate |

Demo

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.
