Struct DefaultRenderLoop 

pub struct DefaultRenderLoop { /* private fields */ }

Default implementation of the application render loop.

The render loop is responsible for advancing the animation timer and updating the scene graph for visible windows. It owns the sleep/wake state machine: setting the timer’s tick to a callback to start the timer and to None to stop it, under a lock so that timer implementations never see concurrent changes.

Implementations

impl DefaultRenderLoop

pub fn new(timer: Arc<dyn IRenderTimer>) -> Arc<DefaultRenderLoop>

Initializes a new instance of the DefaultRenderLoop class.

pub fn timer(&self) -> &Arc<dyn IRenderTimer>

The timer that drives the loop.

Trait Implementations

impl Drop for DefaultRenderLoop

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl IRenderLoop for DefaultRenderLoop

fn add(&self, i: Arc<dyn IRenderLoopTask>)

Adds an update task.

fn remove(&self, i: &Arc<dyn IRenderLoopTask>)

Removes an update task.

fn runs_in_background(&self) -> bool

Indicates if the rendering is done on a non-UI thread.

fn wakeup(&self)

Wakes up the render loop to schedule the next tick. Thread-safe: can be called from any thread.

fn request_frame_out_of_turn(&self)

Asks for a frame out of turn: a tick as soon as the thread that ticks can produce one. Not from upstream.
