Bug: guessing game rand version

[exploreriii]

let secret_number = rand::thread_rng().gen_range(1..=100);

this example generates an error using modern rand versions

it passes using rand 0.8

Part of this example:

use std::io;

use rand::Rng;

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

    let secret_number = rand::thread_rng().gen_range(1..=100);

    println!("The secret number is: {secret_number}");

    println!("Please input your guess.");

    let mut guess = String::new();

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

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

I was about to raise an issue on this. The problem is the author of the rand crate made some API changes in version 0.9. See here: https://rust-random.github.io/book/update-0.9.html.

This is the correct code:

use std::io;
use rand::prelude::*;

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

    let mut guess = String::new();
    let random_number = rand::rng().random_range(1..=100);


    // Rest of code
