Enum layout_2020::display_list::stacking_context::StackingContextContent

pub(crate) enum StackingContextContent {
    Fragment {
        scroll_node_id: ScrollTreeNodeId,
        reference_frame_scroll_node_id: ScrollTreeNodeId,
        clip_chain_id: ClipChainId,
        section: StackingContextSection,
        containing_block: PhysicalRect<Au>,
        fragment: ArcRefCell<Fragment>,
        is_hit_test_for_scrollable_overflow: bool,
    },
    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_chain_id: ClipChainId

section: StackingContextSection

containing_block: PhysicalRect<Au>

fragment: ArcRefCell<Fragment>

is_hit_test_for_scrollable_overflow: bool

AtomicInlineStackingContainer

An index into StackingContext::atomic_inline_stacking_containers.

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

Fields

index: usize
