Trait Cmp

pub trait Cmp<Rhs = Self> {
    type Output;
}

A type operator for comparing Self and Rhs. It provides a similar functionality to the function core::cmp::Ord::cmp but for types.

Example

use typenum::{Cmp, Ord, N3, P2, P5};
use std::cmp::Ordering;

assert_eq!(<P2 as Cmp<N3>>::Output::to_ordering(), Ordering::Greater);
assert_eq!(<P2 as Cmp<P2>>::Output::to_ordering(), Ordering::Equal);
assert_eq!(<P2 as Cmp<P5>>::Output::to_ordering(), Ordering::Less);

Required Associated Types

type Output

The result of the comparison. It should only ever be one of Greater, Less, or Equal.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
