failed to resolve: use of undeclared type or module `exitcode`

[stappersg]

Hi,

In-depth topic 2.3 Exit codes has in its example lines like these:

        Ok(_) => {
            println!("Done!");
            std::process::exit(exitcode::OK);
        }

Upon compiling simular lines I do get

error[E0433]: failed to resolve: use of undeclared type or module `exitcode`
  --> src/main.rs:54:28
   |
54 |         std::process::exit(exitcode::OK);
   |                            ^^^^^^^^ use of undeclared type or module `exitcode`

I think the example code needs something like

use std::process::exit;

but adding such line is not enough.

Did you add exitcode as a dependency?

There is no mention of the dependency in the book anywhere. If you can make a PR that adds a note about the dependency used, it will be helpful. Thanks
