Struct BoxFragmentRareData 

pub(crate) struct BoxFragmentRareData {
    pub(crate) resolved_sticky_insets: Option<Box<PhysicalSides<AuOrAuto>>>,
    pub specific_layout_info: Option<SpecificLayoutInfo>,
}

Fields

resolved_sticky_insets: Option<Box<PhysicalSides<AuOrAuto>>>

The resolved box insets if this box is position: sticky. These are calculated during StackingContextTree construction because they rely on the size of the scroll container.

specific_layout_info: Option<SpecificLayoutInfo>

Information that is specific to a layout system (e.g., grid, table, etc.).

Implementations

impl BoxFragmentRareData

fn try_boxed_from( specific_layout_info: Option<SpecificLayoutInfo>, ) -> AtomicRefCell<Option<Box<Self>>>

Create a new rare data based on information given to the fragment. Ideally, We should avoid creating rare data as much as possible to reduce the memory cost.

Trait Implementations

impl Default for BoxFragmentRareData

fn default() -> BoxFragmentRareData

Returns the “default value” for a type.

impl MallocSizeOf for BoxFragmentRareData

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.
