Fields

shadow_root: Option<Dom<ShadowRoot>>

https://dom.spec.whatwg.org/#dom-element-shadowroot The ShadowRoot this element is host of.

custom_element_reaction_queue: Vec<CustomElementReaction>

https://html.spec.whatwg.org/multipage/#custom-element-reaction-queue

custom_element_definition: Option<Rc<CustomElementDefinition>>

https://dom.spec.whatwg.org/#concept-element-custom-element-definition

custom_element_state: CustomElementState

https://dom.spec.whatwg.org/#concept-element-custom-element-state

name_attribute: Option<Atom>

The “name” content attribute; not used as frequently as id, but used in named getter loops so it’s worth looking up quickly when present

client_rect: Option<LayoutValue<Rect<i32>>>

The client rect reported by layout.

element_internals: Option<Dom<ElementInternals>>

https://html.spec.whatwg.org/multipage#elementinternals

registered_intersection_observers: Vec<IntersectionObserverRegistration>

https://w3c.github.io/IntersectionObserver/#element-private-slots

Element objects have an internal [[RegisteredIntersectionObservers]] slot, which is initialized to an empty list. This list holds IntersectionObserverRegistration records, which have:

cryptographic_nonce: String

forwarded_part_names: Vec<(String, String)>

part: MutNullableDom<DOMTokenList>

Trait Implementations

impl Default for ElementRareData

fn default() -> ElementRareData

Returns the “default value” for a type.

impl MallocSizeOf for ElementRareData

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 ElementRareData

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

Trace self.
