unsafe fn from_jsval( cx: *mut JSContext, value: Handle<'_, Value>, _config: <Root<Dom<T>> as FromJSValConvertible>::Config, ) -> Result<ConversionResult<Root<Dom<T>>>, ()>
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.Source§impl<T> MallocSizeOf for Root<Dom<T>>where

fn size_of(&self, _ops: &mut MallocSizeOfOps) -> usize
