WitrynaAn order is a total order if it is (for all a, b and c ): total and antisymmetric: exactly one of a &lt; b, a == b or a &gt; b is true; and. transitive, a &lt; b and b &lt; c implies a &lt; c. The same must hold for both == and &gt;. When this trait is derive d, it produces a lexicographic ordering. This trait can be used with # [derive].
