EZMenu

Fast designing menus for your Rust CLI programs.

This crate provides a derive(Menu) procedural macro to easily build menus. It includes type-checking from the user input, and a formatting customization.

Documentation

You can find all the crate documentation on Docs.rs. You can also check the examples to learn with a practical way.

Example

Here is an example of how to use it:

use ezmenu::Menu;

fn check(n: &i32) {
    if *n == 0 {
        println!("yo respect me plz :'(");
    } else {
        println!("good. :)");
    }
}

#[derive(Menu)]
struct MyMenu {
    author: String,
    #[field(msg = "Give a nonzero number", then(check))]
    number: u32,
}

To display the menu, you instantiate the struct by calling its from_menu method:

let MyMenu { author, number } = MyMenu::from_menu();
println!("values provided: author={}, number={}", author, number);

This sample code prints the standard menu like above:

- author: Ahmad
- Give a nonzero number: 0
yo respect me plz :'(
values provided: author=Ahmad, number=0
