    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);
}

编译错误：

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

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

    let secret_number = rand::thread_rng().gen_range(0, 101);
    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 …
