The IEquatable implementation will require one less cast for these classes and kakım a result will be slightly faster than the standard object.Equals method that would be used otherwise. Kakım an example see the different implementation of the two methods:

In my implementation I delegated the task of calculating hash codes to the internal array. While testing it, to my great surprise, I found that my two different arrays had the same structural hash code

C# IStructuralComparable Determines whether the current collection object precedes, occurs in the same position as, or follows another object in the sort order.

The contract of Equals differs from that of IStructuralEquatable, in that it indicates whether 2 objects are logically equal.
