Struct webrender::spatial_node::ReferenceFrameInfo

pub struct ReferenceFrameInfo {
    pub source_transform: PropertyBinding<LayoutTransform>,

    pub origin_in_parent_reference_frame: LayoutVector2D,
    pub is_pipeline_root: bool,
}

Contains information about reference frames.

Fields

source_transform: PropertyBinding<LayoutTransform>

The source transform and perspective matrices provided by the stacking context that forms this reference frame. We maintain the property binding information here so that we can resolve the animated transform and update the tree each frame.

transform_style: TransformStyle

kind: ReferenceFrameKind

origin_in_parent_reference_frame: LayoutVector2D

The original, not including the transform and relative to the parent reference frame, origin of this reference frame. This is already rolled into the `transform’ property, but we also store it here to properly transform the viewport for sticky positioning.

is_pipeline_root: bool

True if this is the root reference frame for a given pipeline. This is only used by the hit-test code, perhaps we can change the interface to not require this.

Trait Implementations

impl Clone for ReferenceFrameInfo

fn clone(&self) -> ReferenceFrameInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ReferenceFrameInfo

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

Formats the value using the given formatter.

impl PartialEq<ReferenceFrameInfo> for ReferenceFrameInfo

fn eq(&self, other: &ReferenceFrameInfo) -> 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 ReferenceFrameInfo

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

Serialize this value into the given Serde serializer.

impl Copy for ReferenceFrameInfo
