}

Data specific to the Document root node.

The document node participates in layout and styling like an element, so it carries the same style/layout fields that were previously stored directly on Node.

Fields

content_type: &'static str

ids: HashMap<String, Vec<NodeId>>

Ownership index for detached documents. The live document retains its existing ID map. Lookup verifies ancestry and current tree order.

quirks_mode: u8

0 is standards, 1 is limited quirks, and 2 is quirks.

stylo_element_data: StyloData

selector_flags: Cell<ElementSelectorFlags>

Selector flags deposited here by apply_selector_flags when a for_parent() flag is applied while matching the root <html> element, whose parent node is the document.

guard: Option<SharedRwLock>

A clone of the document’s shared style lock. Set when the owning Node is constructed.

dirty_descendants: Atomic<bool>

element_state: ElementState

has_snapshot: bool

snapshot_handled: Atomic<bool>

style: Style<Atom<AtomStaticSet>>

subtree_hoists: bool

See ElementData::subtree_hoists.

style_source: Option<Arc<ComputedValues>>

See ElementData::style_source. The document node is styled and laid out like an element, so it carries the same hazard.

display_constructed_as: Display

unrounded_layout: Layout

final_layout: Layout

scroll_offset: Point<f64>

scrollable_overflow: Rect

transform: Option<Affine>

Implementations

impl DocumentData

pub fn cache(&self) -> &Cache

As ElementData::cache. There is only one document node, so this saves nothing by itself; it exists so both node kinds present the same accessor and the forwarding on Node stays uniform.

pub fn cache_mut(&mut self) -> &mut Cache

pub fn cache_release(&mut self)

pub fn new() -> DocumentData

Trait Implementations

impl Clone for DocumentData

fn clone(&self) -> DocumentData

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DocumentData

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for DocumentData

fn default() -> DocumentData

Returns the “default value” for a type.
