Hi Miguel!

It leaves unanswered, the question of whether (and how) to use something
like the &raw feature, which requires Rust 1.82.0, given that the
stated min Rust version is 1.78.

Is there some sort of exception to the "min Rust version"? I haven't
figured out where that is written down.


thanks,
