In small print it says the data is collected over 2022 and 2023.
So you're point is that your custom home grown workaround to a failure of C++ doesn't play well with Rusts official solution to the same problem? And therefore Rusts solution isn't better than C++ lack of a solution?
While that is unfortunate for you and you certainly seem to have tech-debted yourself into a particularly nasty corner, I'm not sure that logic follows.
