Documentation: Derive Tutorial

I’ve tried to run the example under “Configuring the Parser” and get some errors. What could be my problem?

Errors

  • error: cannot find derive macro Parser in this scope
  • error: cannot find attribute command in this scope
  • error: cannot find attribute arg in this scope
  • error[E0599]: no function or associated item named parse found for struct Cli in the current scope

Cargo.toml

[package]
name = "hello_cargo"
version = "0.1.0"
edition = "2021"

[dependencies]
clap = "4.3.5"

    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.
