Auto merge of #20265 - Xanewok:fix-js-objects-in-unions, r=jdm
Fix JS object conversion in unions <!-- Please describe your changes on the following line: --> Requires safe `Heap::boxed` constructor from https://github.com/servo/rust-mozjs/pull/395 (more info on it is in the PR). Since unions currently assume that their respective members root themselves and can be stored on heap, I modified the union member object conversion branch to convert to a `RootedTraceableBox<Heap<*mut JSObject>>` (which is the currently generated type for objects in said unions). I did it only for Unions and not dictionaries, since some dictionaries had bare `*mut JSObject` members - is this a mistake and something that needs further fixing? Does this need a test, e.g. passing a union with object to a function that returns said object, and comparing the results for equality? r? @jdm Generated code with this patch (for `StringOrObject`): ```rust impl FromJSValConvertible for StringOrObject { type Config = (); unsafe fn from_jsval(cx: *mut JSContext, value: HandleValue, _option: ()) -> Result<ConversionResult<StringOrObject>, ()> { if value.get().is_object() { match StringOrObject::TryConvertToObject(cx, value) { Err(_) => return Err(()), Ok(Some(value)) => return Ok(ConversionResult::Success(StringOrObject::Object(value))), Ok(None) => (), } } // (...) } } impl StringOrObject { // (...) unsafe fn TryConvertToObject(cx: *mut JSContext, value: HandleValue) -> Result<Option<RootedTraceableBox<Heap<*mut JSObject>>>, ()> { Ok(Some(RootedTraceableBox::from_box(Heap::boxed(value.get().to_object())))) } } ``` --- <!-- Thank you for contributing to Servo!
