Hello I have also encountered this issue, so to fix it it should be written as so.

let secret_number = rand::rng().random_range(1..=100);

you can use this

use std::io;
use rand::Rng;
use std::cmp::Ordering;

fn main() {
    println!("Guess the number!");

    let secret_number = rand::rng().random_range(1..=100);
    loop {
        println!("Enter a number:");

        let mut guess = String::new();

        io::stdin()
            .read_line(&mut guess)
            .expect("Failed to read line");

        let guess: u32 = match guess.trim().parse() {
            Ok(num) => num,
            Err(_) => continue,
        };

        println!("You guessed: {}", guess);

        match guess.cmp(&secret_number) {
            Ordering::Less => println!("Too small!"),
            Ordering::Greater => println!("Too big!"),
            Ordering::Equal => {
                println!("You won 🎉!");
                break;
            }
        }
    }
}
