Struct BoxTree 

pub struct BoxTree {
    root: BlockFormattingContext,
    pub(crate) viewport_overflow: AxesOverflow,
}

Fields

root: BlockFormattingContext

Contains typically exactly one block-level box, which was generated by the root element. There may be zero if that element has display: none.

viewport_overflow: AxesOverflow

Whether or not the viewport should be sensitive to scrolling input events in two axes

Implementations

impl BoxTree

pub(crate) fn construct( context: &LayoutContext<'_>, root_element: ServoLayoutNode<'_>, ) -> Self

fn viewport_overflow( root_element: ServoThreadSafeLayoutNode<'_>, root_box: Option<&ArcRefCell<BlockLevelBox>>, ) -> AxesOverflow

impl BoxTree

pub(crate) fn layout( &self, layout_context: &LayoutContext<'_>, viewport: UntypedSize2D<Au>, ) -> FragmentTree

Trait Implementations

impl MallocSizeOf for BoxTree

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.
