ashpd 0.13.13 GlobalShortcuts bind_shortcuts Request response shortcuts docs.rs

💡 Result:

<search_synthesis>
In ashpd version 0.13.13, the bind_shortcuts method is part of the GlobalShortcuts interface, which is located in the ashpd::desktop::global_shortcuts module and requires the global_shortcuts crate feature to be enabled [1][2][3]. The bind_shortcuts method is defined as follows [4]: pub async fn bind_shortcuts( &self, session: &Session<Self>, shortcuts: &[NewShortcut], identifier: Option<&WindowIdentifier>, options: BindShortcutsOptions,) -> Result<Request<BindShortcuts>, Error> Key components: 1. NewShortcut: Used to define the shortcuts being requested, constructed via NewShortcut::new(id, description) and optionally configured with.preferred_trigger [2][5]. 2. BindShortcutsOptions: A struct for specifying options, including a handle_token [4][6]. 3. Response: The method returns a Request<BindShortcuts> [4]. The BindShortcuts struct represents the response received from the portal, providing a.shortcuts method that returns a slice of the successfully bound Shortcut objects [4][1][2]. This API maps to the org.freedesktop.portal.GlobalShortcuts.BindShortcuts D-Bus interface [4][2].

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 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&`#39`;s camera ```rust use ashpd::desktop::camera::Camera; pub async fn run() -> ashpd::Result<()> { let camera = Camera::new().await?; if camera.is_present().await? { camera.request_access(Default::default()).await?; let remote_fd = camera.open_pipe_wire_remote(Default::default()).await?; // pass the remote fd to GStreamer for example } Ok(()) } ``` ## Optional features | Feature | Description | Default | | --- | --- | --- | | tracing | Record various debug information using the `tracing` library | No | | tokio | Enable tokio runtime on zbus dependency | Yes | | async-io | Enable the use of the async-io crates, compatible with runtimes such smol or glib | No | | backend | unstable Enables APIs useful for writing portals implementations | No | | glib | Make all the enums derive `glib::Enum`.

ashpd 0.13.13 Request response method portal cancellation error docs.rs

💡 Result:

<search_synthesis>
In ashpd 0.13.13, portal interaction management and cancellation are handled through the Request object, which is returned when calling a portal method [1][2]. When a portal interaction occurs, the application receives a Request object. To retrieve the result, the application calls the Request::response method, which returns a Result<T, Error> [1][3]. This Error type can encapsulate various issues, including those related to the portal request&#39;s outcome [4]. Regarding cancellation and error handling: 1. Cancellation: If the user cancels the interaction, the Response signal typically results in a ResponseError::Cancelled variant [3][5]. 2. Manual Cancellation: Applications can manually abort an ongoing interaction by calling the Request::close method [1][3]. When this method is used, the portal request is closed, and a "Response" signal will not be emitted, effectively ending the interaction without triggering the standard response handling [1][3]. 3. Error Representation: The library maps portal response outcomes to its own internal types. If a request does not succeed, it often surfaces through the ResponseError enum, which contains Cancelled and Other variants [3][5]. Furthermore, internal portal errors during the DBus call are handled via the PortalError type (e.g., PortalError::Cancelled) [4]. Recent updates have improved the mapping between these backend errors and standard portal response codes to ensure consistent reporting, particularly distinguishing between user cancellation and other types of failures [6].

<title>Request in ashpd::desktop - Rust</title> https://docs.rs/ashpd/latest/ashpd/desktop/struct.Request.html Request in ashpd::desktop - Rust Skip to main content # Struct Request ``` pub struct Request<T>(/* private fields */) where T: for<&`#39`;de> Deserialize<&`#39`;de> + Type + Debug; ``` Expand description The Request interface is shared by all portal interfaces. When a portal method is called, the reply includes a handle (i.e. object path) for a Request object, which will stay alive for the duration of the user interaction related to the method call. The portal indicates that a portal request interaction is over by emitting the “Response” signal on the Request object. The application can abort the interaction calling close() on the Request object.

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 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&`#39`;s camera ```rust use ashpd::desktop::camera::Camera; pub async fn run() -> ashpd::Result<()> { let camera = Camera::new().await?; if camera.is_present().await? { camera.request_access(Default::default()).await?; let remote_fd = camera.open_pipe_wire_remote(Default::default()).await?; // pass the remote fd to GStreamer for example } Ok(()) } ``` ## Optional features | Feature | Description | Default | | --- | --- | --- | | tracing | Record various debug information using the `tracing` library | No | | tokio | Enable tokio runtime on zbus dependency | Yes | | async-io | Enable the use of the async-io crates, compatible with runtimes such smol or glib | 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 ` for `gdk4::RGBA` Provides `WindowIdentifier::from_native` that takes a `IsA ` | No | | gtk4_wayland | Provides `WindowIdentifier::from_native` that takes a `IsA ` with Wayland backend support only | No | | gtk4_x11 | Provides `WindowIdentifier::from_native` that takes a `IsA ` 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 | | backend | Enables portal backend implementation supoport | 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. ## Backend demo The library also comes with a backend demo that exemplifies how to implement a portal backend. <title>request.rs - source</title> https://docs.rs/ashpd/latest/src/ashpd/desktop/request.rs.html 21/// A typical response returned by the [`Request::response`]. ... 22/// of a [`Request`]. ... 23#[derive(Debug, Type)] 24#[zvariant(signature = "(ua{sv})")] 25pub enum Response<T> { 26 /// Success, the request is carried out. ...

Handle the portal bind response.

bind_shortcuts returns Result<Request<BindShortcuts>, Error>. The current code drops the Request, so it does not observe cancellation or inspect the BindShortcuts::shortcuts() list. If the portal binds no shortcuts, the GUI still waits for activation signals without warning.

Proposed fix

                 .bind_shortcuts(&session, &shortcuts, None, BindShortcutsOptions::default())
                 .await
             {
-                log::warn!("Failed to bind global shortcuts: {err}");
-                std::future::pending::<()>().await;
-                return;
-            }
