Struct Application 

pub struct Application(/* private fields */);

A reference to a GPUI application, typically constructed in the main function of your app. You won’t interact with this type much outside of initial configuration and startup.

Implementations

impl Application

Represents an application before it is fully launched. Once your app is configured, you’ll start the app with App::run.

pub fn new() -> Self

Builds an app with the given asset source.

pub fn headless() -> Self

Build an app in headless mode. This prevents opening windows, but makes it possible to run an application in an context like SSH, where GUI applications are not allowed.

pub fn with_assets(self, asset_source: impl AssetSource) -> Self

Assign

pub fn with_http_client(self, http_client: Arc<dyn HttpClient>) -> Self

Sets the HTTP client for the application.

pub fn with_quit_mode(self, mode: QuitMode) -> Self

Configures when the application should automatically quit. By default, QuitMode::Default is used.

pub fn run<F>(self, on_finish_launching: F)

where F: 'static + FnOnce(&mut App),

Start the application. The provided callback will be called once the app is fully launched.

pub fn on_open_urls<F>(&self, callback: F) -> &Self

where F: 'static + FnMut(Vec<String>),

Register a handler to be invoked when the platform instructs the application to open one or more URLs.

pub fn on_reopen<F>(&self, callback: F) -> &Self

where F: 'static + FnMut(&mut App),

Invokes a handler when an already-running application is launched. On macOS, this can occur when the application icon is double-clicked or the app is launched via the dock.

pub fn background_executor(&self) -> BackgroundExecutor

Returns a handle to the BackgroundExecutor associated with this app, which can be used to spawn futures in the background.

pub fn foreground_executor(&self) -> ForegroundExecutor

Returns a handle to the ForegroundExecutor associated with this app, which can be used to spawn futures in the foreground.

pub fn text_system(&self) -> Arc<TextSystem>

Returns a reference to the TextSystem associated with this app.

pub fn path_for_auxiliary_executable(&self, name: &str) -> Result<PathBuf>

Returns the file URL of the executable with the specified name in the application bundle
