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;
use ashpd::WindowIdentifier;

async fn run() -> ashpd::Result<()> {
    let connection = zbus::azync::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

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

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

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

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.

Type Definitions

Result

Alias for a Result with the error type ashpd::Error.
