Fields

node_count: usize

user_overridden_properties: Vec<Vec<(CssPropertyType, CssProperty)>>

cascaded_props: FlatVecVec<StatefulCssProperty>

css_props: FlatVecVec<StatefulCssProperty>

computed_values: Vec<Vec<(CssPropertyType, CssPropertyWithOrigin)>>

compact_cache: Option<CompactLayoutCache>

global_css_props: Vec<CssProperty>

resolved_font_sizes_px: OnceLock<Vec<f32>>

Per-node resolved font-size, in pixels, for the Normal pseudo-state. Populated lazily on first call to [crate::styled_dom::StyledDom::resolved_font_size_px] via a single bottom-up DOM walk; subsequent reads are O(1) Vec index by NodeId::index().

Motivation: get_font_size is called ~730× per node per layout pass (see AZ_PROP_COUNT=1 report — 329 629 cascade walks on excel.html alone). Each resolution recursively reads the parent’s font-size (for em) plus the root’s font-size (for rem), multiplying the walk count. Caching the pre-resolved pixel value collapses that to a single Vec<f32> indexed lookup.

Implementations

impl CssPropertyCache

pub fn memory_breakdown(&self) -> CssPropertyCacheBreakdown

Approximate heap bytes retained by this cache, broken out by subfield. Used by StyledDom::memory_breakdown + the AZ_MEM_BREAKDOWN=1 reporter. Sums capacity × element size for each Vec and adds a coarse allowance for the inner Vec headers inside computed_values.

This is a measurement helper, not a tight bound — it doesn’t chase into the CssProperty enum variants that carry their own Vec/String allocations (notably FontFamily → StyleFontFamilyVec → Vec<StyleFontFamily>), so the real heap footprint for a property-rich DOM can be 2-3× these numbers. Still useful for spotting gross duplication between the pre-compact and compact caches.

pub fn prune_compact_normal_props(&mut self)

Drop Normal-state properties that have compact encodings from css_props and cascaded_props. After build_compact_cache_with_inheritance, these are redundant — the compact cache is the source of truth for layout. Non-Normal entries (hover/active/focus) and non-compact properties (background, box-shadow, transform, etc.) are kept for get_property_slow.

impl CssPropertyCache

pub fn restyle( &mut self, css: &mut Css, node_data: &NodeDataContainerRef<'_, NodeData>, node_hierarchy: &NodeHierarchyItemVec, non_leaf_nodes: &ParentWithNodeDepthVec, html_tree: &NodeDataContainerRef<'_, CascadeInfo>, ) -> Vec<TagIdToNodeIdMapping>

Match CSS selectors to nodes and populate css_props. Returns tag IDs for hit-testing. If compact_cache is available, uses it for fast display/overflow checks; otherwise falls back to slow path.

pub fn generate_tag_ids( &self, node_data: &NodeDataContainerRef<'_, NodeData>, node_hierarchy: &NodeHierarchyItemVec, ) -> Vec<TagIdToNodeIdMapping>

Generate hit-test tag IDs for nodes that need event handling. Uses compact cache (if available) for fast display/overflow reads. Can be called separately after build_compact_cache_with_inheritance.

pub fn get_computed_css_style_string( &self, node_data: &NodeData, node_id: &NodeId, node_state: &StyledNodeState, ) -> String

impl CssPropertyCache

pub fn empty(node_count: usize) -> Self

pub fn invalidate_resolved_font_sizes(&mut self)

Clear the lazily-populated font-size cache. Call after any mutation that could change resolved font-sizes (restyle, DOM mutation, append, etc.). The next [crate::styled_dom::StyledDom::resolved_font_size_px] call repopulates via a single bottom-up tree walk.

pub fn apply_ua_css(&mut self, node_data: &[NodeData])

Applies user-agent (UA) CSS properties to the cascade before inheritance.

UA CSS has the lowest priority in the cascade, so it should only be applied if the node doesn’t already have the property from inline styles or author CSS.

This is critical for text nodes: UA CSS properties (like font-weight: bold for H1) must be in the cascade maps so they can be inherited by child text nodes.

Uses a bitset per node to avoid O(n²) scanning of property vecs.

pub fn sort_cascaded_props(&mut self)

Sort cascaded_props by (state, prop_type) and flatten into contiguous memory. Must be called after apply_ua_css() which adds entries to cascaded_props.

pub fn compute_inherited_values( &mut self, node_hierarchy: &[NodeHierarchyItem], node_data: &[NodeData], ) -> Vec<NodeId>

Compute inherited values for all nodes in the DOM tree.

Implements CSS inheritance: walk tree depth-first, apply cascade priority (inherited → cascaded → css → inline → user), create dependency chains for relative values. Call apply_ua_css() before this function.

impl CssPropertyCache

pub fn build_compact_cache( &self, node_data: &[NodeData], prev_font_hashes: &[u64], ) -> CompactLayoutCache

Build a CompactLayoutCache from the current property cache state.

Must be called after restyle(), apply_ua_css(), and compute_inherited_values(). Resolves all layout-relevant properties for every node in the “normal” state (no hover/active/focus) and encodes them into compact arrays.

Tier 1/2/2b provide fast-path access for layout-hot properties. Non-compact properties (background, transform, box-shadow, etc.) are resolved via the slow cascade path in get_property_slow().

prev_font_hashes is the per-node font hash array from the previous frame. When non-empty, each node’s new font_family_hash is compared against the previous value, and differing nodes are recorded in font_dirty_nodes. On the first build (empty slice), ALL text nodes are marked dirty.

pub fn build_compact_cache_with_inheritance( &self, node_data: &[NodeData], node_hierarchy: &[NodeHierarchyItem], prev_font_hashes: &[u64], ) -> CompactLayoutCache

Build compact cache with inheritance in a single pass.

Replaces the separate compute_inherited_values() + build_compact_cache() calls. For each node (in DOM index order, which is pre-order = parents before children):

1. Copy parent’s compact values for INHERITABLE properties
2. Apply this node’s CSS properties on top (from css_props + inline + UA)
3. Write directly to compact arrays

This eliminates 50K Vec clones from compute_inherited_values and avoids re-reading properties from 5 separate data structures.

pub fn build_compact_cache_with_inheritance_debug( &self, node_data: &[NodeData], node_hierarchy: &[NodeHierarchyItem], prev_font_hashes: &[u64], debug_messages: &mut Option<Vec<LayoutDebugMessage>>, ) -> CompactLayoutCache

Same as build_compact_cache_with_inheritance but with optional debug logging.

Trait Implementations

impl Clone for CssPropertyCache

fn clone(&self) -> CssPropertyCache

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CssPropertyCache

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

Formats the value using the given formatter.

impl Default for CssPropertyCache

fn default() -> CssPropertyCache

Returns the “default value” for a type.

impl PartialEq for CssPropertyCache

fn eq(&self, other: &CssPropertyCache) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StructuralPartialEq for CssPropertyCache
