Trait Implementations

impl DomObject for ResizeObserver

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 ResizeObserver

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

Function pointer to the general wrap function type

impl HasParent for ResizeObserver

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 ResizeObserver

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

Returns whether the given DOM class derives that interface.

impl MallocSizeOf for ResizeObserver

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 ResizeObserver

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

Initializes the Reflector

impl PartialEq for ResizeObserver

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 ResizeObserverMethods<DomTypeHolder> for ResizeObserver

fn Constructor( window: &Window, proto: Option<HandleObject<'_>>, can_gc: CanGc, callback: Rc<ResizeObserverCallback>, ) -> Root<Dom<ResizeObserver>>

https://drafts.csswg.org/resize-observer/#dom-resizeobserver-resizeobserver

fn Observe(&self, target: &Element, options: &ResizeObserverOptions)

https://drafts.csswg.org/resize-observer/#dom-resizeobserver-observe

fn Unobserve(&self, target: &Element)

https://drafts.csswg.org/resize-observer/#dom-resizeobserver-unobserve

fn Disconnect(&self)

https://drafts.csswg.org/resize-observer/#dom-resizeobserver-disconnect

impl ToJSValConvertible for ResizeObserver

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

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

impl Traceable for ResizeObserver

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

Trace self.
