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.
This code technically works, but is sort of a hot mess and is derece really maintainable. Anyone using the library would have to write this code birli well. The next logical step would be to just use .Equals on the entire metrics.
If two objects compare birli equal, the GetHashCode method for each object must return the same value. However, if two objects do hamiş compare as equal, the GetHashCode methods for the two object do derece have to return different values.
The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects. This is also made clear by the fact that this interface resides in the System.Collections namespace.
