Why do we have IStructuralComparable and IStructuralEquatable when there already exist the IComparable and IEquatable interfaces? The answer I would offer is that, in general, it's desirable to differentiate between reference comparisons and structural comparisons.

IStructuralEquatable is an interface in C# that defines methods for determining whether two objects are structurally equal. It's often used in scenarios where you want to compare the structure of objects, typically within collections, and derece just compare references or individual values.

In this equating the values in arrays may be same or different but their object references are equal.

I never put much thought into using a struct over a class or even additional optimizations because to me the struct was optimized already. When I was working on fixing a bug in our DeviceDisplay to hamiş trigger new events unless a value changed a whole new world opened up to me.
