Synchronous messages that script can send to layout.

In general, you should use messages to talk to Layout. Use the RPC interface if and only if the work is

1. read-only with respect to LayoutThreadData,
2. small,
3. and really needs to be fast.

Required Methods

fn content_box(&self) -> ContentBoxResponse

Requests the dimensions of the content box, as in the getBoundingClientRect() call.

fn content_boxes(&self) -> ContentBoxesResponse

Requests the dimensions of all the content boxes, as in the getClientRects() call.

fn node_geometry(&self) -> NodeGeometryResponse

Requests the geometry of this node. Used by APIs such as clientTop.

fn scrolling_area(&self) -> NodeGeometryResponse

Requests the scroll geometry of this node. Used by APIs such as scrollTop.

fn node_scroll_id(&self) -> NodeScrollIdResponse

Requests the scroll id of this node. Used by APIs such as scrollTop

fn resolved_style(&self) -> ResolvedStyleResponse

Query layout for the resolved value of a given CSS property

fn resolved_font_style(&self) -> Option<Arc<Font>>

Query layout to get the resolved font style for canvas.

fn offset_parent(&self) -> OffsetParentResponse

fn text_index(&self) -> TextIndexResponse

fn nodes_from_point_response(&self) -> Vec<UntrustedNodeAddress>

Requests the list of nodes from the given point.

fn element_inner_text(&self) -> String

Query layout to get the inner text for a given element.

fn inner_window_dimensions(&self) -> Option<Size2D<f32, CSSPixel>>

Get the dimensions of an iframe’s inner window.
