It's normally expected that if you implement IEquatable.Equals you will also override Object.Equals to be consistent. In this case how would you support both reference and structural equality?

This is really amazing code and works great for .Kemiksiz Standard libraries. If you are in a .NET Core 2.1 application there is an even cooler way of doing this:
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 not just compare references or individual values.
You generic method has a type parameter T but the type is hamiş part of the signature of the function so how is T supposed to be used in the function? Anyway, you yaşama use .Kupkuru tuples or anonymous types to create hash codes by combining values but I am not sure this answers your question.

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

In Xamarin.Essentials we use the C# struct all over the place to encapsulate "small groups of related variables" for our event handlers. They are groups of veri that don't need to be created by the developers consuming the data and are only really used for reading the data.

Default property. The second time, it passes the default equality comparer C# IStructuralEquatable nedir that is returned by the StructuralComparisons.StructuralEqualityComparer property. The third time, it passes the custom NanComparer object. Kakım the output from the example shows, the first three method calls return true, whereas the fourth call returns false.
