在Rust中，我需要什么特征来比较泛型和整数

use std::cmp::{PartialEq, PartialOrd};

fn compare<T: PartialEq + PartialOrd>(a: T, b: T) {
    if a == b {
        println!("Values are equal");
    } else if a < b {
        println!("First value is less than second value");
    } else {
        println!("First value is greater than second value");
    }
}

fn main() {
    compare(5, 10);  // Output: First value is less than second value
    compare("hello", "world");  // Output: First value is less than second value
    compare(3.14, 3.14);  // Output: Values are equal
}
