Struct AnimationRefreshDriverObserver 

pub(crate) struct AnimationRefreshDriverObserver {
    pub(crate) constellation_sender: Sender<EmbedderToConstellationMessage>,
    pub(crate) animating: Cell<bool>,
}

The AnimationRefreshDriverObserver is the default implementation of a RefreshDriver on systems without vsync hardware integration. It has a very basic way of triggering frames using a timer. It prevents new animation frames until the timer has fired.

Fields

constellation_sender: Sender<EmbedderToConstellationMessage>

The channel on which messages can be sent to the Constellation.

animating: Cell<bool>

Whether or not we are currently animating via a timer.

Implementations

impl AnimationRefreshDriverObserver

pub(crate) fn new( constellation_sender: Sender<EmbedderToConstellationMessage>, ) -> Self

pub(crate) fn notify_animation_state_changed( &self, webview_renderer: &WebViewRenderer, ) -> bool

Trait Implementations

fn frame_started(&self, painter: &mut Painter) -> bool
