Enum StackingContextContent

pub(crate) enum StackingContextContent {
    Fragment {
        scroll_node_id: ScrollTreeNodeId,
        reference_frame_scroll_node_id: ScrollTreeNodeId,
        clip_id: ClipId,
        section: StackingContextSection,
        containing_block: PhysicalRect<Au>,
        fragment: Fragment,
        is_hit_test_for_scrollable_overflow: bool,
        is_collapsed_table_borders: bool,
        text_decorations: Arc<Vec<FragmentTextDecoration>>,
    },
    AtomicInlineStackingContainer {
        index: usize,
    },
}

A piece of content that directly belongs to a section of a stacking context.

This is generally part of a fragment, like its borders or foreground, but it can also be a stacking container that needs to be painted in fragment order.

Variants

Fragment

A fragment that does not generate a stacking context or stacking container.

Fields

scroll_node_id: ScrollTreeNodeId

reference_frame_scroll_node_id: ScrollTreeNodeId

clip_id: ClipId

section: StackingContextSection

containing_block: PhysicalRect<Au>

fragment: Fragment

is_hit_test_for_scrollable_overflow: bool

is_collapsed_table_borders: bool

text_decorations: Arc<Vec<FragmentTextDecoration>>

AtomicInlineStackingContainer

An index into StackingContext::atomic_inline_stacking_containers.

There is no section field, because these are always in StackingContextSection::Foreground.

Fields

index: usize

Implementations

impl StackingContextContent

pub(crate) fn section(&self) -> StackingContextSection

fn build_display_list( &self, builder: &mut DisplayListBuilder<'_>, inline_stacking_containers: &[StackingContext], )

Trait Implementations

impl MallocSizeOf for StackingContextContent

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.
