Struct TimerRefreshDriver 

struct TimerRefreshDriver {
    sender: Sender<TimerThreadMessage>,
    join_handle: Option<JoinHandle<()>>,
}

A thread that manages a TimerScheduler running in the background of the RefreshDriver. This is necessary because we need a reliable way of waking up the embedder’s main thread, which may just be sleeping until the EventLoopWaker asks it to wake up.

It would be nice to integrate this somehow into the embedder thread, but it would require both some communication with the embedder and for all embedders to be well behave respecting wakeup timeouts – a bit too much to ask at the moment.

Fields

sender: Sender<TimerThreadMessage>

join_handle: Option<JoinHandle<()>>

Implementations

impl TimerRefreshDriver

fn queue_timer(&self, duration: Duration, callback: BoxedTimerCallback)

Trait Implementations

impl Default for TimerRefreshDriver

fn default() -> Self

Returns the “default value” for a type.

impl Drop for TimerRefreshDriver

fn drop(&mut self)

Executes the destructor for this type.

impl RefreshDriver for TimerRefreshDriver

fn observe_next_frame( &self, new_start_frame_callback: Box<dyn Fn() + Send + 'static>, )

Servo will call this method when it wants to be informed of the next frame start time. Implementors should call the callback when it is time to start preparing the new frame.
