How to optimize this code and more readable with struct or enum?

[dry tulip]

const CMD: [[&str; 2]; 3] = [["ECHO", "echo "],
                                ["QUIT", ":q"],
                                ["HELP", "?"]];

Why not just have a three-value enum and a method that converts it into a string?

Alternatively, have a value of type [(MyEnum, &str); 3]

Actually, what do you mean by "optimize"?

enum Command {
  Echo,
  Quit,
  Help,
}
impl Command {
  fn as_shortcut_text(&self) -> &'static str {
    match self {
      Self::Echo => "echo",
      Self::Quit => ":q",
      Self::Help => "?",
    }
  }
}

It's to clean up the code

In programming, "optimize" actually means, "make the code run faster". I'd suggest avoiding using that word with that meaning in the future 😅

Oh sorry 😅
