That is, you emanet create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface.

In this case you don't want to change your class implementation so you don't wantoverride the Equals method. this will define a general way to compare objects in your application.

Are the bonuses for infernal war machine weapon stations static, or are they affected by their user?

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 derece just compare references or individual values.

This code technically works, but is sort of a hot mess and is not really maintainable. Anyone using the library would have to write this code kakım well. The next logical step would be to just use .Equals on the entire metrics.

Structural equality means that two objects are equal because they have equal values. It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.

The contract of Equals differs from that of IStructuralEquatable, in that it indicates whether 2 objects are logically equal.

Just look at the default ValueType.Equals(object) code that gets called otherwise. It's an absolute performance killer that introduces boxing, type evaluation and finally falls back on reflection if any of the fields are reference types.
