expected {&unknown}, found String

I can't compare guess with word and it throws me an expected {&unknown}, found String. error

fn main() {
    let mut guess = String::new();
    let word: String = String::from("Hello, world");

    for x in 1..10 {
        io::stdin()
            .read_line(&mut guess)
            .except("failed to read line");

        println!("{}", guess.eq(word)); //error is in this line
    }

    println!("Game is over");
}

You must borrow word when you are comparing to it. So write guess.eq(&word). But this is equivalent to guess == word, so I would recommend this instead.

Also when you are reading line the endline character '\n' will also be added to guess, so you should probably use guess.trim() before compering to discard leading and trailing whitespaces.
