where T: Castable, Self: DerivedFrom<T>,

Cast a DOM object upwards to one of the interfaces it derives from.

fn downcast<T>(&self) -> Option<&T>

where T: DerivedFrom<Self>,

Cast a DOM object downwards to one of the interfaces it might implement.

impl DomObject for HTMLTrackElement

type ReflectorType = ()

fn reflector(&self) -> &Reflector<Self::ReflectorType>

Returns the receiver’s reflector.

fn SetSrclang(&self, cx: &mut JSContext, value: DOMString)

fn Label(&self) -> DOMString

fn SetLabel(&self, cx: &mut JSContext, value: DOMString)

fn Default(&self) -> bool

fn SetDefault(&self, cx: &mut JSContext, value: bool)

impl HasParent for HTMLTrackElement

fn as_parent(&self) -> &HTMLElement

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

type Parent = HTMLElement

impl IDLInterface for HTMLTrackElement

const PROTO_FIRST: u16 = 286

First prototype ID in the DFS-ordered range for this interface and its descendants.

const PROTO_LAST: u16 = 286

Last prototype ID in the DFS-ordered range for this interface and its descendants.

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

Returns whether the given DOM class derives that interface.

impl MallocSizeOf for HTMLTrackElement

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 HTMLTrackElement

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

Initializes the Reflector

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

Initializes the Reflector without recording any associated memory usage.

impl PartialEq for HTMLTrackElement

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 HTMLTrackElement

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

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

fn safe_to_jsval(&self, cx: &mut JSContext, rval: MutableHandle<'_, Value>)
