Just to clarify a bit, the test ofc isn't a fully general solution to solving issues with database migrations (I hinted what that might be in the blog post), although it's still useful to provide a nice error message even if a more general solution was implemented.

That was not at all the goal of the post. I just wanted to appreciate how easy it was to achieve this specific task in Rust. In any other systems programming language that I used (even most other languages, except maybe for Python), I would never even imagine something like this being feasible, and so easy to do. That's it :)
