How to check whether a string is palindrome or not in Rust

Answer 1

fn is_palindrome(str: String) -> bool {
    let half = str.len() / 2;
    
    let first_half = str.bytes().take(half);
    let last_rev_half = str.bytes().rev().take(half);
    
    return first_half.eq(last_rev_half)
}

fn main()
{        
    let string : String = "rotator".to_string();

    if is_palindrome(string) {
        println!("Palindrome");
    }
    else {
        println!("Not Palindrome");
    }
}
