VelvetIO - Simple CLI Input for Rust

Getting user input in Rust CLI apps is annoying. VelvetIO makes it simple.

use velvetio::prelude::*;

let name = ask!("What's your name?");
let age = ask!("How old are you?" => u32);

if confirm!("Do you like Rust?") {
    println!("Great choice, {}!", name);
}

For complex input, use forms:

use velvetio::prelude::*;

let user_data = form()
    .text("name", "Full name")
    .number("age", "Age")
    .choice("role", "Role", &["User", "Admin"])
    .collect();
