That is, you kişi create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface.
Now, when we call Equals ourselves it will directly call our new fancy Equals that takes in a ScreenMetrics, which is great.
It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.

You generic method saf a type parameter T but the type is not part of the signature of the function so how is T supposed to be used in the function? Anyway, you sevimli use .Kupkuru tuples or anonymous types to create hash codes by combining values but I am not sure this answers your question.
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 derece trigger new events unless a value changed a whole new world opened up to me.
1 My understanding is that it's used for collection like types, and encapsulates the structural part of the comparison, but leaved the comparison of the elements to a comparer passed in by the user. But I'm not really sure if I really got it.

Defines methods to support the comparison of objects for structural equality. Structural equality means that two objects are equal because they have equal values.
Default property. The second time, it passes the default equality comparer that is returned by the StructuralComparisons.StructuralEqualityComparer property. The third time, it passes the custom NanComparer object. Bey the output from the example shows, the first three method calls return true, whereas the fourth call returns false.
While writing my own immutable ByteArray class that uses a byte array internally, I implemented the IStructuralEquatable interface.
