Struct TraversalState 

pub(crate) struct TraversalState {
    pub spatial_id: ScrollTreeNodeId,
    pub clip_id: ClipId,
    pub origin: PhysicalPoint<Au>,
    pub text_decorations: Rc<Vec<FragmentTextDecoration>>,
    pub accumulated_opacity: f32,
    pub containing_element_tag: Option<Tag>,
    pub container_timing_roots: Option<Rc<ContainerTimingRootChain>>,
}

Fields

spatial_id: ScrollTreeNodeId

clip_id: ClipId

origin: PhysicalPoint<Au>

text_decorations: Rc<Vec<FragmentTextDecoration>>

accumulated_opacity: f32

The product of the used opacity of the fragments visited.

containing_element_tag: Option<Tag>

https://www.w3.org/TR/paint-timing/#sec-modifications-dom:

The tag of the nearest ancestor box that determines the containing block of text, used to group text fragments for LCP.

container_timing_roots: Option<Rc<ContainerTimingRootChain>>

The Container Timing roots enclosing this point in the traversal, nearest first. Note that this does not include the box currently being visited, see Self::container_timing_roots_including.

Implementations

impl TraversalState

pub(crate) fn push_box_fragment( &self, box_fragment: &BoxFragmentWithStyle<'_>, ) -> Self

pub(crate) fn container_timing_roots_including( &self, box_fragment: &BoxFragment, ) -> Option<Rc<ContainerTimingRootChain>>

The Container Timing roots that apply to the given box fragment, which is visited with this state, including the fragment itself if it is a root.

pub(crate) fn without_text_decorations(&self) -> Self

pub(crate) fn push_positioning_fragment( &self, positioning_fragment: &PositioningFragment, ) -> Self

pub(crate) fn push_stacking_context( &self, stacking_context: &StackingContext, ) -> Self
