Trait Implementations

impl DomObject for MediaSession

fn reflector(&self) -> &Reflector

Returns the receiver’s reflector.

impl DomObjectWrap<DomTypeHolder> for MediaSession

const WRAP: unsafe fn(SafeJSContext, &GlobalScope, Option<HandleObject<'_>>, Box<Self>, CanGc) -> Root<Dom<Self>> = {script_bindings::codegen::GenericBindings::MediaSessionBinding::Wrap::<dom::bindings::codegen::DomTypeHolder::DomTypeHolder> as for<'a, 'b> unsafe fn(script_bindings::script_runtime::JSContext, &'a dom::globalscope::GlobalScope, std::option::Option<js::rust::Handle<'b, *mut js::jsapi::JSObject>>, std::boxed::Box<dom::media::mediasession::MediaSession>, script_bindings::script_runtime::CanGc) -> script_bindings::root::Root<script_bindings::root::Dom<dom::media::mediasession::MediaSession>>}

Function pointer to the general wrap function type

impl HasParent for MediaSession

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 MediaSession

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

Returns whether the given DOM class derives that interface.

impl MallocSizeOf for MediaSession

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 MediaSessionMethods<DomTypeHolder> for MediaSession

fn GetMetadata(&self, can_gc: CanGc) -> Option<DomRoot<MediaMetadata>>

https://w3c.github.io/mediasession/#dom-mediasession-metadata

fn SetMetadata(&self, metadata: Option<&MediaMetadata>)

https://w3c.github.io/mediasession/#dom-mediasession-metadata

fn PlaybackState(&self) -> MediaSessionPlaybackState

https://w3c.github.io/mediasession/#dom-mediasession-playbackstate

fn SetPlaybackState(&self, state: MediaSessionPlaybackState)

https://w3c.github.io/mediasession/#dom-mediasession-playbackstate

fn SetActionHandler( &self, action: MediaSessionAction, handler: Option<Rc<MediaSessionActionHandler<DomTypeHolder>>>, )

https://w3c.github.io/mediasession/#update-action-handler-algorithm

fn SetPositionState( &self, state: &MediaPositionState, can_gc: CanGc, ) -> Fallible<()>

https://w3c.github.io/mediasession/#dom-mediasession-setpositionstate

impl MutDomObject for MediaSession

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

Initializes the Reflector

impl PartialEq for MediaSession

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 MediaSession

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

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

impl Traceable for MediaSession

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

Trace self.
