what if i need to if let on the result of another if let

Oh, then you use and_then() or something similar.

There's also the possibility to use the guard clauses patern and do let <...> = <...> else {}.

And finally, you can always split into another function.

It's not straight rules. It depends on what makes it more readable for your case.
