Fields

reflector_: Reflector

attached: Cell<bool>

If attached is false, we’re using this to hold form-related state on an element for which attachInternals() wasn’t called yet; this is necessary because it might have a form owner.

target_element: Dom<HTMLElement>

validity_state: MutNullableDom<ValidityState>

validation_message: DomRefCell<DOMString>

custom_validity_error_message: DomRefCell<DOMString>

validation_anchor: MutNullableDom<HTMLElement>

submission_value: DomRefCell<SubmissionValue>

state: DomRefCell<SubmissionValue>

form_owner: MutNullableDom<HTMLFormElement>

labels_node_list: MutNullableDom<NodeList>

Trait Implementations

impl DomObject for ElementInternals

fn reflector(&self) -> &Reflector

Returns the receiver’s reflector.

fn global(&self) -> Root<Dom<GlobalScope>>

where Self: Sized,

Returns the global scope of the realm that the DomObject was created in.

impl HasParent for ElementInternals

fn as_parent(&self) -> &Reflector

This is used in a type assertion to ensure that the source and webidls agree as to what the parent type is

type Parent = Reflector

impl IDLInterface for ElementInternals

fn derives(class: &'static DOMClass) -> bool

Returns whether the given DOM class derives that interface.

impl MallocSizeOf for ElementInternals

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 MutDomObject for ElementInternals

unsafe fn init_reflector(&self, obj: *mut JSObject)

Initializes the Reflector

impl PartialEq for ElementInternals

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ToJSValConvertible for ElementInternals

unsafe fn to_jsval(&self, cx: *mut JSContext, rval: MutableHandleValue<'_>)

Convert self to a JSVal. JSAPI failure causes a panic.

impl Traceable for ElementInternals

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

Trace self.
