Implementations

impl<D: DomTypes> ElementOrDocument<D>

unsafe fn TryConvertToElement( cx: SafeJSContext, value: HandleValue<'_>, ) -> Result<Option<DomRoot<D::Element>>, ()>

unsafe fn TryConvertToDocument( cx: SafeJSContext, value: HandleValue<'_>, ) -> Result<Option<DomRoot<D::Document>>, ()>

Trait Implementations

impl<D: DomTypes> Clone for ElementOrDocument<D>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<D: DomTypes> FromJSValConvertible for ElementOrDocument<D>

type Config = ()

Optional configurable behaviour switch; use () for no configuration.

unsafe fn from_jsval( cx: *mut JSContext, value: HandleValue<'_>, _option: (), ) -> Result<ConversionResult<ElementOrDocument<D>>, ()>

Convert val to type Self. Optional configuration of type T can be passed as the option argument. If it returns Err(()), a JSAPI exception is pending. If it returns Ok(Failure(reason)), there is no pending JSAPI exception.

impl<D> MallocSizeOf for ElementOrDocument<D>

where D: MallocSizeOf + DomTypes,

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<D: DomTypes> ToJSValConvertible for ElementOrDocument<D>

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

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

impl<D> Traceable for ElementOrDocument<D>

where D: JSTraceable + DomTypes,

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

Trace self.
