Trait Implementations

impl Castable for MediaQueryList

fn is<T>(&self) -> boolwhere
    T: DerivedFrom<Self>,

Check whether a DOM object implements one of its deriving interfaces.

fn upcast<T>(&self) -> &Twhere
    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 MediaQueryList

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 DomObjectWrap for MediaQueryList

const WRAP: unsafe fn(_: SafeJSContext, _: &GlobalScope, _: Box<Self>) -> Root<Dom<Self>> = {dom::bindings::codegen::Bindings::MediaQueryListBinding::MediaQueryListBinding::Wrap as for<'a> unsafe fn(script_runtime::JSContext, &'a dom::globalscope::GlobalScope, std::boxed::Box<dom::mediaquerylist::MediaQueryList>) -> dom::bindings::root::Root<dom::bindings::root::Dom<dom::mediaquerylist::MediaQueryList>>}

Function pointer to the general wrap function type

impl HasParent for MediaQueryList

fn as_parent(&self) -> &EventTarget

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

type Parent = EventTarget

impl IDLInterface for MediaQueryList

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

Returns whether the given DOM class derives that interface.

impl JSTraceable for MediaQueryList

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

Trace self.

impl MallocSizeOf for MediaQueryList

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 MediaQueryListMethods for MediaQueryList

fn Media(&self) -> DOMString

fn Matches(&self) -> bool

fn AddListener(&self, listener: Option<Rc<EventListener>>)

fn RemoveListener(&self, listener: Option<Rc<EventListener>>)

fn GetOnchange(&self) -> Option<Rc<EventHandlerNonNull>>

fn SetOnchange(&self, listener: Option<Rc<EventHandlerNonNull>>)

impl MutDomObject for MediaQueryList

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

Initializes the Reflector

impl PartialEq<MediaQueryList> for MediaQueryList

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl ToJSValConvertible for MediaQueryList

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

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

impl WeakReferenceable for MediaQueryList

fn downgrade(&self) -> WeakRef<Self>

Downgrade a DOM object reference to a weak one.

impl DerivedFrom<EventTarget> for MediaQueryList
