Struct AttributeStorage 

pub(crate) struct AttributeStorage(DomRefCell<Vec<AttributeEntry>>);

Storage for an element’s attributes. Contains an internal DomRefCell so that ensure_dom can split its borrow around Attr::new() allocation, preventing GC-during-allocation panics from double-borrowing.

Tuple Fields

0: DomRefCell<Vec<AttributeEntry>>

Implementations

impl AttributeStorage

pub(crate) fn borrow(&self) -> AttributesBorrow<'_>

Borrow the attributes for read access with convenient AttrRef iteration.

pub(crate) unsafe fn borrow_for_layout(&self) -> &Vec<AttributeEntry>

Borrow the underlying entries for layout access (unsafe).

pub(crate) fn push_raw(&self, data: ContentAttributeData)

Push raw attribute data.

pub(crate) fn push_dom(&self, attr: &Attr)

Push a Dom Attr node.

pub(crate) fn remove(&self, index: usize) -> AttributeEntry

Remove an attribute by index, returning the entry.

pub(crate) fn set(&self, index: usize, entry: AttributeEntry)

Set an attribute entry by index.

pub(crate) fn ensure_dom( &self, index: usize, element: &Element, ) -> DomRoot<Attr>

Ensure entry at index is a Dom Attr node, materializing if needed. Returns a DomRoot<Attr>.

This method carefully splits the mutable borrow around the Attr::new() allocation so that GC tracing can safely borrow the storage.

Trait Implementations

impl Default for AttributeStorage

fn default() -> AttributeStorage

Returns the “default value” for a type.

impl MallocSizeOf for AttributeStorage

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.

impl Traceable for AttributeStorage

unsafe fn trace(&self, trc: *mut JSTracer)

Trace self.
