Not only that, any code examples in rustdoc are treated like tests and get executed during compilation! That ensures that your examples are not obsolete (or at least that they compile).

That is a genuinely great idea.

I believe it's also how it works in go documentation. Examples are executed at compile time.

Didn't realize this was possible with Sphinx (Python) until I saw your comment and did some digging. Here's the relevant documentation if anyone else is curious:

such is life, especially in dynlangs, things got added, it's already cool that it's known and works finely as it is.

maybe one day domains, limits and code/proofs will be a single entity in source

Not without external tooling, as far as I'm aware.

With rust this is built into the default tools installed by rustup.

Write doctests in your docstrings, run python -m doctest
