Struct DocumentData 

pub struct DocumentData {
    pub stylo_element_data: StyloData,
    pub selector_flags: Cell<ElementSelectorFlags>,
    pub guard: Option<SharedRwLock>,
    pub dirty_descendants: AtomicBool,
    pub damaged_descendants: AtomicBool,
    pub element_state: ElementState,
    pub has_snapshot: bool,

}

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

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: AtomicBool

damaged_descendants: AtomicBool

element_state: ElementState

has_snapshot: bool

snapshot_handled: AtomicBool

display_constructed_as: Display

layout_data: Option<Box<LayoutData>>

Layout output state (None until layout first writes to this node).

transform: Option<Box<Affine>>

Implementations

impl DocumentData

pub fn layout_data(&self) -> &LayoutData

The document node’s layout output state, or a shared default if layout has never written to it.

pub fn layout_data_mut(&mut self) -> &mut LayoutData

Mutable access to the document node’s layout output state, allocating it if it does not yet exist.

impl DocumentData

pub fn new() -> Self

Trait Implementations

fn clone(&self) -> Self

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

Formats the value using the given formatter.

impl Default for DocumentData

fn default() -> Self

Returns the “default value” for a type.
