Struct DisplayLinkTimer 

pub struct DisplayLinkTimer { /* private fields */ }

Render timer driven by a CADisplayLink, paused while the render loop is idle or the application is in the background.

Implementations

impl DisplayLinkTimer

pub fn new() -> Arc<DisplayLinkTimer>

Creates the timer and starts its thread. The options of the platform (Platform::options) are read here, so the platform has them first.

Panics

Panics when the thread cannot be started.

pub fn timer_thread(&self) -> &Thread

The thread of the display link: where the timer ticks and, the timer running in the background, where the compositor renders.

impl DisplayLinkTimer

pub fn ticks(&self) -> u64

The number of times the display link fired, whether or not a frame was asked for. An addition of the port, for diagnostics.

pub fn has_tick(&self) -> bool

Whether a tick handler is set: whether the render loop runs.

Trait Implementations

impl IRenderTimer for DisplayLinkTimer

fn tick(&self) -> Option<RenderTimerTick>

Gets the callback to be invoked when the timer ticks.

fn set_tick(&self, value: Option<RenderTimerTick>)

Sets the callback to be invoked when the timer ticks.

fn runs_in_background(&self) -> bool

Indicates if the timer ticks on a non-UI thread.

fn request_tick_out_of_turn(&self)

Asks for a tick out of turn: as soon as the thread that ticks can produce one, without waiting for the next period of the timer (the next frame of a display). Not from upstream.
