minus-squareRustyNova@lemmy.worldlinkfedilinkarrow-up1·7 个月前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.
