This seems a big silly. This is not a language issue. You can have a C++ library that does exactly all the things being shown here so that the application developer doesn't worry about. There would no C++ language features missing that would accomplish what you're able to do on the Rust side.
So is this really a language comparison, or what libraries are available for each language platform? If the latter, that's fine. But let's be clear about what the issue is. It's not the language, it's what libraries are included out of the box.
