Function display_utils::cmp

pub fn cmp<T: Display>(this: T, other: &str) -> Ordering

Lexicographically compares a Display object against a string.

cmp(a, b) is functionally equivalent to a.to_string().cmp(b), but requires no allocations.

use std::cmp::Ordering;

assert_eq!(cmp(true, "trud"), Ordering::Greater);
assert_eq!(cmp(true, "true"), Ordering::Equal);
assert_eq!(cmp(true, "truf"), Ordering::Less);
