Struct webrender::spatial_node::SceneSpatialNode

pub struct SceneSpatialNode {
    pub snapping_transform: Option<ScaleOffset>,
    pub parent: Option<SpatialNodeIndex>,
    pub descriptor: SpatialNodeDescriptor,
    pub is_root_coord_system: bool,
}

Scene building specific representation of a spatial node, which is a much lighter subset of a full spatial node constructed and used for frame building

Fields

snapping_transform: Option<ScaleOffset>

Snapping scale/offset relative to the coordinate system. If None, then we should not snap entities bound to this spatial node.

parent: Option<SpatialNodeIndex>

Parent spatial node. If this is None, we are the root node.

descriptor: SpatialNodeDescriptor

Descriptor describing how this spatial node behaves

is_root_coord_system: bool

If true, this spatial node is known to exist in the root coordinate system in all cases (it has no animated or complex transforms)

Implementations

impl SceneSpatialNode

pub fn new_reference_frame( parent_index: Option<SpatialNodeIndex>, transform_style: TransformStyle, source_transform: PropertyBinding<LayoutTransform>, kind: ReferenceFrameKind, origin_in_parent_reference_frame: LayoutVector2D, pipeline_id: PipelineId, is_root_coord_system: bool, is_pipeline_root: bool ) -> Self

pub fn new_scroll_frame( pipeline_id: PipelineId, parent_index: SpatialNodeIndex, external_id: ExternalScrollId, frame_rect: &LayoutRect, content_size: &LayoutSize, frame_kind: ScrollFrameKind, external_scroll_offset: LayoutVector2D, offset_generation: APZScrollGeneration, has_scroll_linked_effect: HasScrollLinkedEffect, is_root_coord_system: bool ) -> Self

pub fn new_sticky_frame( parent_index: SpatialNodeIndex, sticky_frame_info: StickyFrameInfo, pipeline_id: PipelineId, is_root_coord_system: bool ) -> Self

fn new( pipeline_id: PipelineId, parent_index: Option<SpatialNodeIndex>, node_type: SpatialNodeType, is_root_coord_system: bool ) -> Self

Trait Implementations

impl PartialEq<SceneSpatialNode> for SceneSpatialNode

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for SceneSpatialNode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
