Day 9:
Is there a reason why the method https://github.com/vinodotdev/node-to-rust/blob/4ba560485704f543306e50395a17638284934b45/src/crates/day-9/structs/src/main.rs#L29 is not used anywhere in that code?

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

  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.

I just want to thank you for your series mate !
Great read, keep it up.

hello, @jsoverson ,

Thank you for providing us with such a good ebook for learning Rust. I want Rust enthusiasts in China to also learn this ebook. Can I fork this repo and translate it into Chinese?

thanks

Hi, this error will be easy for ruby developers but I'm not a ruby developer and I can't solve it although investigating in google. That's the error:

$ make deps
bundle install
/opt/homebrew/opt/ruby/bin/bundle:25:in `load': cannot load such file -- /opt/homebrew/Cellar/ruby/3.3.0/lib/ruby/gems/3.3.0/gems/bundler-2.5.7/exe/bundle (LoadError)
	from /opt/homebrew/opt/ruby/bin/bundle:25:in `<main>'
make: *** [deps] Error 1

How can I solve that? Thanks.

When describing the solution for getState, initially the implementation pub fn get_state(&self) -> &String is given along with a usefull explanation which matches the struct types.

But for the "full code" implementation immediately following, it changes to pub fn get_state(&self) -> &str which I found confusing since the distinction between them is not covered and the apparent String -> &str "cohersion" in the second version is not made clear inline.

at https://github.com/wasmflow/node-to-rust/blob/master/book/chapters/chapter-15-closures.adoc#basic-closure-syntax

let closure = () \=> {
  console.log("Hi! I'm in a closure");
};
closure();

has weird \=> for some reason and it's appear all over the book.
Not sure what it was. You can assign to me if it's a bug I will take a look.

Cheers
