Struct LaunchedEffectScope 

pub struct LaunchedEffectScope { /* private fields */ }

Implementations

impl LaunchedEffectScope

pub fn is_active(&self) -> bool

pub fn runtime(&self) -> RuntimeHandle

pub fn launch(&self, task: impl FnOnce(LaunchedEffectScope) + 'static)

Runs a follow-up LaunchedEffect task on the UI thread.

The provided closure executes on the runtime thread and may freely capture Rc/RefCell state. This must only be called from the UI thread, typically inside another effect callback.

pub fn post_ui(&self, task: impl FnOnce() + 'static)

Posts UI-only work that will execute on the runtime thread.

The closure never crosses threads, so it may capture non-Send values. Callers must invoke this from the UI thread.

pub fn post_ui_send(&self, task: impl FnOnce() + Send + 'static)

Posts work from any thread to run on the UI thread.

The closure must be Send because it may be sent across threads before running on the runtime thread. Use this helper when posting from background threads that need to interact with UI state.

pub fn launch_background<T, Work, Ui>(&self, work: Work, on_ui: Ui)

where T: Send + 'static, Work: FnOnce(CancelToken) -> T + Send + 'static, Ui: FnOnce(T) + 'static,

Runs background work on a worker thread and delivers results to the UI.

work executes on a background thread, receives a cooperative CancelToken, and must produce a Send value. The on_ui continuation runs on the runtime thread, so it may capture Rc/RefCell state safely.
