Day 20: CLI Arguments and Logging, a issue with the chapter

[liby]

As mentioned in the section on Adding CLI Arguments

• follow the steps and you will see the following output on the command line

cargo run -p cli -- --help
wasm-runner 0.1.0
Sample project from https://vino.dev/blog/node-to-rust-day-1-rustup/

USAGE:
    cli

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

The example code at this point should look like this

  use my_lib::Module;
  use structopt::{clap::AppSettings, StructOpt};

  #[macro_use]
  extern crate log;

  #[derive(StructOpt)]
  #[structopt(
      name = "wasm-runner",
      about = "Sample project from https://vino.dev/blog/node-to-rust-day-1-rustup/",
      global_settings(&[
          AppSettings::ColoredHelp
      ]),
  )]
  struct CliOptions {}

  fn main() {
      env_logger::init();
      debug!("Initialized logger");

      match Module::from_file("./module.wasm") {
          Ok(_) => {
              info!("Module loaded");
          }
          Err(e) => {
              error!("Module failed to load: {}", e);
          }
      }
  }

Now when we run our cli we see… nothing at all.
