Crate 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

use ashpd::desktop::screenshot::ScreenshotProxy;

async fn run() -> Result<(), ashpd::Error> {
    let connection = zbus::azync::Connection::new_session().await?;

    let proxy = ScreenshotProxy::new(&connection).await?;
    let color = proxy.pick_color(Default::default()).await?;

    println!("({}, {}, {})", color.red(), color.green(), color.blue());

    Ok(())
}

Start a PipeWire stream from the user’s camera

use ashpd::desktop::camera::CameraProxy;

pub async fn run() -> Result<(), ashpd::Error> {
    let connection = zbus::azync::Connection::new_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(())
}

For a tour of the various portals, see the ASHPD demo application.

Optional features

Feature	Description
feature_gtk3	Implement From<Color> for gdk3::RGBA
	Provides WindowIdentifier::from_window
feature_gtk4	Implement From<Color> for gdk4::RGBA
	Provides WindowIdentifier::from_window

Re-exports

pub use enumflags2;
pub use zbus;
pub use zvariant;

Modules

desktop	Interact with the user’s desktop such as taking a screenshot, setting a background or querying the user’s location.
documents	Interact with the documents store or transfer files across apps.
flatpak	Spawn commands outside the sandbox or monitor if the running application has received an update & install it.

Enums

Error	The error type for ashpd.
WindowIdentifier	Most portals interact with the user by showing dialogs. These dialogs should generally be placed on top of the application window that triggered them. To arrange this, the compositor needs to know about the application window. Many portal requests expect a WindowIdentifier for this reason.

Functions

is_sandboxed

Check whether the application is running inside a sandbox.
