Description
Code
use std::io;
use std::cmp::Ordering;
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");
let guess: u32 = guess.trim().parse().expect("Please type a number: ");
println!("You guessed: {guess}");
match guess.cmp(&secret_number) {
Ordering::Less => println!("Too small!");
Ordering::Greater => println!("Too big!"),
Ordering::Equal => println!("You won!"),
}
}Current output

|Rationale and extra context
The reason why it should be changed is because the new error message makes it clearer you should replace ; with ,. I was following the book, and I encountered this error. I didn't understand how to solve it and asked on the community discord, then a user in the community server then helped me and I managed to fix the error.
