The tutorial makes a reference to this
This requires enabling the derive feature flag.
But if you aren't as familiar with feature flags, this isn't as helpful.
More specifically on the front page we have
$ cargo add clap --features deriveMaybe we should push that down into the tutorial...
That's the point. I didn't know about the feature flags feature of Rust/Cargo. Of course, if you know it, you "have to" skip it in each tutorial. IMHO, it should be okay 🙂 Thank you for your answer.
