Constantly prompt user in rust

use std::io;

fn main() {

    // hardcoded answer
    let answer: &str = "The letter e";

    // mutable response
    let mut response: String = String::new();
    
    // counting trials
    let mut trials: usize = 0;

    // While the response is not equal to answer, keep prompting use.
    while response.trim_end() != answer { // trim_end() gets rid of user's newline
        response.clear(); // Clear before each interval.
        println!("I am the beginning of the end, and the end of time and space. I am essential to creation, and I surround every place. What am I?");
        io::stdin()
            .read_line(&mut response) // trim trailing newline
            .expect("No input");
        // Increment the trial count after user has responded.
        trials += 1;
    }
    println!("Number of trials: {}", trials)
}
