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::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(())
}

Optional features

Feature	Description	Default

tokio	Enable tokio runtime on zbus dependency	Yes
async-std	Enable the use of the async-std runtime	No
backend	unstable Enables APIs useful for writing portals implementations	No
glib	Make all the enums derive `glib::Enum`. Flags are not supported yet	No
gtk4	Implement `From<Color>` for `gdk4::RGBA` Provides `WindowIdentifier::from_native` that takes a `IsA<gtk4::Native>`	No
gtk4_wayland	Provides `WindowIdentifier::from_native` that takes a `IsA<gtk4::Native>` with Wayland backend support only	No
gtk4_x11	Provides `WindowIdentifier::from_native` that takes a `IsA<gtk4::Native>` with X11 backend support only	No
pipewire	Provides `ashpd::desktop::camera::pipewire_streams` that helps you retrieve the various camera streams associated with the retrieved file descriptor	No
raw_handle	Provides `WindowIdentifier::from_raw_handle` and `WindowIdentifier::as_raw_handle` for raw-window-handle crate	No
wayland	Provides `WindowIdentifier::from_wayland` for wayland-client crate	No

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.
