                    println!("{name},{},{}", c.installed, c.available);
                }

                // Print the `cargo install` commands for outdated crates
                // for command in outdated
                //     .iter()
                //     .map(|(_name, c)| c.update_command().join(" "))
                // {
                //     println!("{command}");
                // }

                // Update outdated crates
                // outdated.iter().for_each(|(_name, c)| c.update());
            }
        }
    }
    Err(e) => {
        eprintln!("Error: {e}");
    }
}

If you want to include just a subset of the crates, instead of Crates::from(&path), use Crates::from_include(&path, &patterns) where patterns is a slice of &str regex patterns.
