It will never be this bad in an actual use case, there are some cases where you will have a few of them nested in each other but it's not too bad. Rust is just a very verbose language in some areas because of it's strict type system but that's also what makes Rust so powerful, it's by design. Though I will admit, Rust being so verbose in some areas kind of scared me away from it for a long time, but I've grown to like it a lot and it's actually really good and worth learning if you're ever bored. The borrow checker and type system are your friends
