Expand description

Result of a layout pass for a single DOM, before display list generation

Fields§

§styled_dom: StyledDom

The styled DOM that was laid out

§layout_tree: LayoutTree

The layout tree with computed sizes and positions

§calculated_positions: BTreeMap<usize, LogicalPosition>

Absolute positions of all nodes

§viewport: LogicalRect

The viewport used for this layout

§display_list: DisplayList

The generated display list for this DOM.

§scroll_ids: BTreeMap<usize, u64>

Stable scroll IDs computed from node_data_hash Maps layout node index -> external scroll ID

§scroll_id_to_node_id: BTreeMap<u64, NodeId>

Mapping from scroll IDs to DOM NodeIds for hit testing This allows us to map WebRender scroll IDs back to DOM nodes
