How do I compare a Span, e.g., using min() and max() methods?

It is not obvious to me, how I would I compare Spans and use .min() and .max() on them.

You can't use min() and max() on them because they very intentionally don't implement Eq or Ord. Have you seen these parts of the docs?

• Comparisons for Span
• Span::compare

If you don't need to represent calendar durations (units of days or above), then it's possible that you'll want a SignedDuration instead. That type is just like std::time::Duration and has all of the trait impls (like Eq and Ord) that you'd expect. You can read more about how to choose between a Span and a SignedDuration.
