Trait Implementations

impl<D> CallbackContainer<D> for UnderlyingSourceCancelCallback<D>

where D: DomTypes,

unsafe fn new( cx: JSContext, callback: *mut JSObject, ) -> Rc<UnderlyingSourceCancelCallback<D>>

Create a new CallbackContainer object for the given JSObject.

fn callback_holder(&self) -> &CallbackObject<D>

Returns the underlying CallbackObject.

fn callback(&self) -> *mut JSObject

Returns the underlying JSObject.

fn incumbent(&self) -> Option<&<D as DomTypes>::GlobalScope>

Returns the “callback context”, that is, the global to use as incumbent global when calling the callback.

impl<D> PartialEq for UnderlyingSourceCancelCallback<D>

where D: PartialEq + DomTypes,

fn eq(&self, other: &UnderlyingSourceCancelCallback<D>) -> 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<D> ToJSValConvertible for UnderlyingSourceCancelCallback<D>

where D: DomTypes,

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

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

impl<D> Traceable for UnderlyingSourceCancelCallback<D>

where D: DomTypes + Traceable,

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

Trace self.

impl<D> StructuralPartialEq for UnderlyingSourceCancelCallback<D>
