Fields

node_id: Option<NodeId>

local_bounds: Rect

transform_to_parent: ProjectiveTransform

content_offset: Point

motion_context_animated: bool

translated_content_context: bool

translated_content_offset: Point

scene_children_origin: Point

Window-space origin this layer’s children are placed from, and the accumulated ancestor graphics-layer translation, captured during the full per-frame scene build. Read back when a dirty subtree is rebuilt in isolation (update_scene_from_applier) so a scrolling field’s window origin stays live during a fling even though the ancestor chain is not re-walked from the root. Defaults to the identity origin.

scene_children_layer_translation: Point

graphics_layer: GraphicsLayer

clip_to_bounds: bool

shadow_clip: Option<Rect>

hit_test: Option<HitTestNode>

has_hit_targets: bool

isolation: IsolationReasons

cache_policy: CachePolicy

cache_hashes: LayerRasterCacheHashes

cache_hashes_valid: bool

children: Vec<RenderNode>
