Struct NodeChangeReport 

pub struct NodeChangeReport {
    pub change_set: NodeChangeSet,
    pub relayout_scope: RelayoutScope,
    pub changed_css_properties: Vec<CssPropertyType>,
    pub text_change: Option<TextChange>,
}

Per-node change report combining multiple information sources.

Fields

change_set: NodeChangeSet

Bitflags from DOM-level field comparison.

relayout_scope: RelayoutScope

Highest RelayoutScope from any CSS property that changed on this node. This is more granular than NodeChangeSet’s binary LAYOUT/PAINT split.

• None → repaint only (color, opacity, transform)
• IfcOnly → reshape text in the containing IFC
• SizingOnly → recompute this node’s intrinsic size
• Full → full subtree relayout (display, position, float, etc.)

changed_css_properties: Vec<CssPropertyType>

Individual CSS properties that changed (for fine-grained cache invalidation). Empty if the change was structural (text content, node type, etc.)

text_change: Option<TextChange>

If text content changed, the old and new text for cursor reconciliation.

Implementations

impl NodeChangeReport

pub fn needs_layout(&self) -> bool

Returns the DirtyFlag level needed for this change report. Maps RelayoutScope + NodeChangeSet → a simple tri-state.

pub fn needs_paint(&self) -> bool

pub fn is_visually_unchanged(&self) -> bool

fn clone(&self) -> NodeChangeReport

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeChangeReport

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