Trait EventContextAsyncExt 

pub trait EventContextAsyncExt {
    // Required methods
    fn spawn_local(
        &mut self,
        future: impl Future<Output = ()> + 'static,
    ) -> TaskHandle;
    fn spawn_local_with<R: 'static>(
        &mut self,

        on_complete: impl FnOnce(R, &mut EventContext<'_>) + 'static,
    ) -> TaskHandle;
}

Spawn async work on the main-thread executor from inside an event handler.

Brought into scope with use teksilo_async::EventContextAsyncExt; (or via the teksilo prelude when the async feature is on).

Required Methods

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

Spawn a !Send future. It runs on the UI thread and may capture and mutate Signals and other Rc handles directly on resume. Drop the returned TaskHandle to cancel, or call .detach() to fire-and-forget.

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

Spawn a future and deliver its result to on_complete with a fresh EventContext bound to this window’s tree — the supported way to run a one-shot ambient op (open_window, send_intent, …) once the work finishes. The future body itself runs handle-only.

Panics

Panics if called outside a window context (there is no window to bind the completion to). Use spawn_local from such sites and drive UI updates through Signals.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
