This CLI project is a project based learning(PBL) study method in action, it doesn't have the purpose to provide a full and robust implementation of a CLI app made in rust, feel free to fork and create your own by using this model since it's hold by Apache license.
In case you cloned the repository, you can type in your command line
cargo run -- generate (name, phone, address or fullhuman)And the CLI should work just fine.
