beginner question: What is the advantage of using cmp::Ordering::Less over "<", same for Greater and Equals?

I'm guessing you're asking because you got a clippy lint. Using Ordering allows you to match the output therefore only calling partial_ord once, compared to using an if-else chain which might call it several times. In many/most cases this would probably be compiler optimized anyway but this makes it explicit.
