Struct AsyncRuntimeHandle 

pub struct AsyncRuntimeHandle { /* private fields */ }

Handle to the main-thread async runtime. Registered in app-state by install_async and reached from a handler via ctx.spawn_local(...) (EventContextAsyncExt). Clone shares the same executor (Rc); !Send — it only ever lives on the UI thread.

Implementations

impl AsyncRuntimeHandle

pub fn new() -> Self

pub fn poll_source(&self) -> Rc<Cell<bool>>

The shared poll flag passed to on_loop_tick; set while the executor wants continuous polling (a task re-woke synchronously), cleared when idle so the loop can sleep.

pub fn completions(&self) -> AsyncCompletionHandle

The completion registry shared with teksilo-app so it can deliver spawn_local_with results with a fresh EventContext. Registered in app-state under AsyncCompletionHandle.

pub fn set_poster(&self, poster: Arc<dyn AppEventPoster>)

Install the event-loop poster used as the cross-thread wake target and to post completions. Idempotent (set once). Called lazily on the first spawn from ctx.poster().

pub fn tick(&self) -> bool

Advance the executor by one turn: poll every live task that a wake made runnable, dropping completed/cancelled ones. Returns true if it polled tasks (the caller repaints). Normally driven by the on_loop_tick hook; exposed for headless drivers and tests.

pub fn spawn_local( &self, future: impl Future<Output = ()> + 'static, ) -> TaskHandle

Spawn a !Send future on the main-thread executor. The future may capture and mutate Signals and other Rc handles directly. Returns a TaskHandle: drop to cancel, .detach() to fire-and-forget.

pub fn spawn_local_with<R: 'static>( &self, window_id: TeksiloWindowId, future: impl Future<Output = R> + 'static, on_complete: impl FnOnce(R, &mut EventContext<'_>) + 'static, ) -> TaskHandle

Spawn a future whose result is delivered to on_complete with a fresh EventContext bound to window_id’s tree — the supported way to run a one-shot ambient op (open_window, send_intent, …) after await. The future body itself runs handle-only (no EventContext).

Trait Implementations

impl Clone for AsyncRuntimeHandle

fn clone(&self) -> AsyncRuntimeHandle

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for AsyncRuntimeHandle

fn default() -> Self

Returns the “default value” for a type.
