Fields§

§layout_context: &'a LayoutContext<'a>

A LayoutContext reference important for creating WebRender images.

§root_stacking_context: StackingContext

The root of the StackingContext tree.

§stacking_context_info: FnvHashMap<StackingContextId, StackingContextInfo>

StackingContext and ClipScrollNode children for each StackingContext.

§clip_scroll_nodes: Vec<ClipScrollNode>

A vector of ClipScrollNodes which will be given ids during WebRender DL conversion.

§items: FnvHashMap<StackingContextId, Vec<DisplayItem>>

The items in this display list.

§processing_scrolling_overflow_element: bool

Whether or not we are processing an element that establishes scrolling overflow. Used to determine what ClipScrollNode to place backgrounds and borders into.

§current_stacking_context_id: StackingContextId

The current stacking context id, used to keep track of state when building. recursively building and processing the display list.

§current_clipping_and_scrolling: ClippingAndScrolling

The current clip and scroll info, used to keep track of state when recursively building and processing the display list.

§iframe_sizes: FnvHashMap<BrowsingContextId, Size2D<f32, CSSPixel>>

Vector containing iframe sizes, used to inform the constellation about new iframe sizes

§indexable_text: IndexableText

Stores text runs to answer text queries used to place a cursor inside text.
