Implementations

impl<D> UnderlyingSource<D>

where D: DomTypes,

pub fn empty() -> RootedTraceableBox<UnderlyingSource<D>>

pub fn new( cx: &mut JSContext, val: Handle<'_, Value>, ) -> Result<ConversionResult<RootedTraceableBox<UnderlyingSource<D>>>, ()>

impl<D> UnderlyingSource<D>

where D: DomTypes,

pub fn to_jsobject( &self, cx: &mut JSContext, obj: MutableHandle<'_, *mut JSObject>, )

Trait Implementations

impl<D> Clone for UnderlyingSource<D>

where D: DomTypes,

fn clone(&self) -> UnderlyingSource<D>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<D> Default for UnderlyingSource<D>

where D: DomTypes,

fn default() -> UnderlyingSource<D>

Returns the “default value” for a type.

impl<D> ToJSValConvertible for UnderlyingSource<D>

where D: DomTypes,

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

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

impl<D> Traceable for UnderlyingSource<D>

where D: DomTypes + Traceable,

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

Trace self.
