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.
In certain scenarios (such bey using the value type as a key in a dictionary) it dirilik murder performance in one foul swoop.
Will feeblemind affect the original creature's body when it was cast on it while it was polymorphed and reverted to its original form afterwards?

The generic tuple classes (Tuple, Tuple, Tuple, and so on) and the Array class provide explicit implementations of the IStructuralEquatable interface. By casting (in C#) or converting (in Visual Basic) the current instance of an array or tuple to an IStructuralEquatable interface value and providing your IEqualityComparer implementation bey an argument to the Equals method, you sevimli define a custom equality comparison for the array or collection.
Coming soon: Throughout 2024 we will be phasing out GitHub Issues bey the feedback mechanism for content and replacing it with a new feedback system. For more information see: .

That is, you can create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface. The interface saf two members: Equals, which tests for equality by using a specified IEqualityComparer implementation, and GetHashCode, which returns identical hash codes for objects that are equal.
You observations does hamiş conflict with the documentation and there is no bug in the implementation.
3 feature called Tuple Equality! That is right, you gönül create a ValueTuple and simply compare them as they are super optimized, don't create any objects, and reduce this to a single line of code!
