The individual calls to IEqualityComparer.Equals end and the IStructuralEquatable.Equals method returns a value either when a method call returns false or after all array elements or tuple components have been compared.
1 How do such comparators relate to things like Dictionary and other collections? I know that Dictionary seems to handle structures sensibly albeit slowly in .
That is right! When we override Equals we must also override and implement GetHashCode. I am no HashCode expert, but in the same article from Sergey is a snippet of using a ValueTuple to simplify this entire call to 1 line of code just like our fancy ValueTuple Equality above.

You generic method katışıksız a type parameter T but the type is derece part of the signature of the function so how is T supposed to be used in the function? Anyway, you gönül use .Kemiksiz tuples or anonymous types to create hash codes by combining values but I am hamiş sure this answers your question.

In addition to this awesome blog Frank and I also dicussed all of this awesome in detail on Merge Conflict on episode 111:
Each of your objects should use a hashcode based on the contents of the object. If you have a value type containing 3 ints, use those when computing the hash code. Like this, all objects with identical content will have the same hash code, independent of app domain and other circumstances.
IStructuralEquatable is used with arrays to determine whether the arrays are structurally equal. The StructuralEqualityComparer.Equals method is used for this purpose.

However, this is not so great if you are using the struct in a dictionary bey my good friend Dustin mentioned to me because a Dictionary will always use the object version of Equals, which falls back to boxing :(
