Required Associated Types

type Runtime: Runtime<T, Handle = Self>

Required Methods

fn create_proxy(&self) -> <Self::Runtime as Runtime<T>>::EventLoopProxy

Creates an EventLoopProxy that can be used to dispatch user events to the main event loop.

fn request_exit(&self, code: i32) -> Result<()>

Requests an exit of the event loop.

fn create_window<F: Fn(RawWindow<'_>) + Send + 'static>( &self, pending: PendingWindow<T, Self::Runtime>, before_window_creation: Option<F>, ) -> Result<DetachedWindow<T, Self::Runtime>>

Create a new window.

fn create_webview( &self, window_id: WindowId, pending: PendingWebview<T, Self::Runtime>, ) -> Result<DetachedWebview<T, Self::Runtime>>

Create a new webview.

fn run_on_main_thread<F: FnOnce() + Send + 'static>(&self, f: F) -> Result<()>

Run a task on the main thread.

fn display_handle(&self) -> Result<DisplayHandle<'_>, HandleError>

fn primary_monitor(&self) -> Option<Monitor>

fn monitor_from_point(&self, x: f64, y: f64) -> Option<Monitor>

fn available_monitors(&self) -> Vec<Monitor>

fn cursor_position(&self) -> Result<PhysicalPosition<f64>>

fn set_theme(&self, theme: Option<Theme>)

fn find_class<'a>( &self, env: &mut JNIEnv<'a>, activity: &JObject<'_>, name: impl Into<String>, ) -> Result<JClass<'a>, Error>

Finds an Android class in the project scope.

fn run_on_android_context<F>(&self, f: F)

where F: FnOnce(&mut JNIEnv<'_>, &JObject<'_>, &JObject<'_>) + Send + 'static,

Dispatch a closure to run on the Android context.

The closure takes the JNI env, the Android activity instance and the possibly null webview.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
