RemarksThe objects of type Type must be equality-comparable. This requires that the operator== defined on the set of objects satisfies the mathematical properties of an equivalence relation. All of the built-in

On clang 3.5 with a simple example, this compiles the same assembly as a hand-rolled equality operator. See it ongodbolt compiler explorer. Visitation without an instance Besides iteration over aninstanceof a registered struct,visit_structalso supports visiting thedefinitionof the struct. In this...
Equality(DateTimeOffset, DateTimeOffset) Determines whether two specified DateTimeOffset objects represent the same point in time. GreaterThan(DateTimeOffset, DateTimeOffset) Determines whether one specified DateTimeOffset object is greater than (or later than) a second specified DateTimeOffset object. Greater...
