Struct RuntimeHandle 

pub struct RuntimeHandle { /* private fields */ }

Implementations

impl RuntimeHandle

pub fn id(&self) -> RuntimeId

pub fn schedule(&self)

pub fn enqueue_node_update( &self, command: Box<dyn FnMut(&mut dyn Applier) -> Result<(), NodeError> + 'static>, )

pub fn enqueue_ui_task(&self, task: Box<dyn FnOnce() + 'static>)

Schedules work that must run on the runtime thread.

The closure executes on the UI thread immediately when the runtime drains its local queue, so it may capture Rc/RefCell values. Calling this from any other thread is a logic error and will panic in debug builds via the inner assertion.

pub fn spawn_ui<F>(&self, fut: F) -> Option<TaskHandle>

where F: Future<Output = ()> + 'static,

pub fn cancel_task(&self, id: u64)

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

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

The closure must be Send because it may cross threads before executing on the runtime thread. Use this when posting from background work.

pub fn register_ui_cont<T: 'static>( &self, f: impl FnOnce(T) + 'static, ) -> Option<u64>

pub fn cancel_ui_cont(&self, id: u64)

pub fn drain_ui(&self)

pub fn has_pending_ui(&self) -> bool

pub fn register_frame_callback( &self, callback: impl FnOnce(u64) + 'static, ) -> Option<u64>

pub fn cancel_frame_callback(&self, id: u64)

pub fn drain_frame_callbacks(&self, frame_time_nanos: u64)

pub fn frame_clock(&self) -> FrameClock

pub fn set_needs_frame(&self, value: bool)

pub fn has_updates(&self) -> bool

pub fn has_invalid_scopes(&self) -> bool

pub fn has_frame_callbacks(&self) -> bool

pub fn assert_ui_thread(&self)

pub fn dispatcher(&self) -> UiDispatcher
