Fields

pipeline: Option<CompositionPipeline>

The pipeline associated with this PipelineDetails object.

parent_pipeline_id: Option<PipelineId>

The id of the parent pipeline, if any.

animations_running: bool

Whether animations are running

animation_callbacks_running: bool

Whether there are animation callbacks

throttled: bool

Whether to use less resources by stopping animations.

scroll_tree: ScrollTree

The compositor-side ScrollTree. This is used to allow finding and scrolling nodes in the compositor before forwarding new offsets to WebRender.

first_paint_metric: Cell<PaintMetricState>

The paint metric status of the first paint.

first_contentful_paint_metric: Cell<PaintMetricState>

The paint metric status of the first contentful paint.

largest_contentful_paint_metric: Cell<PaintMetricState>

The paint metric status of the largest contentful paint.

viewport_scale: Option<Scale<f32, CSSPixel, DevicePixel>>

The CSS pixel to device pixel scale of the viewport of this pipeline, including page zoom, but not including any pinch zoom amount. This is used to detect situations where the current display list is for an old scale.

exited: PipelineExitSource

Which parts of Servo have reported that this Pipeline has exited. Only when all have done so will it be discarded.

display_list_epoch: Option<Epoch>

The Epoch of the latest display list received for this Pipeline or None if no display list has been received.
