Programming a Guessing Game

To hands-on learn Blyx concepts, let us build a complete guessing game program that generates a secret random number between 1 and 100 and prompts the user to guess it.

use std::io;
use std::rand;

fn main() {
    let secret = rand::thread_rng().gen_range(1..=100);
    println!("Guess the secret number!");

    loop {
        let mut guess = String::new();
        io::stdin().read_line(&mut guess).expect("Failed to read line");
        let guess: i32 = match guess.trim().parse() {
            Ok(num) => num,
            Err(_) => continue,
        };
        if guess == secret {
            println!("You win!");
            break;
        }
    }
}
