Implementations

impl<D: DomTypes> UnderlyingSink<D>

pub(crate) unsafe fn to_jsobject( &self, cx: *mut JSContext, obj: MutableHandleObject<'_>, )

impl<D: DomTypes> UnderlyingSink<D>

pub(crate) fn empty() -> RootedTraceableBox<Self>

pub(crate) fn new( cx: SafeJSContext, val: HandleValue<'_>, ) -> Result<ConversionResult<RootedTraceableBox<UnderlyingSink<D>>>, ()>

Trait Implementations

impl<D: DomTypes> Default for UnderlyingSink<D>

fn default() -> Self

Returns the “default value” for a type.

impl<D: DomTypes> ToJSValConvertible for UnderlyingSink<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 UnderlyingSink<D>

where D: JSTraceable + DomTypes,

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

Trace self.
