I want to write a function that either returns an object that has already been AddRefed or an nsresult error. Result<already_AddRefed<...>, nsresult> doesn't seem to work. Result<RefPtr<...>, nsresult> would presumably work, but might wastefully touch the object's refcount. Is there a better way? _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
