It is determined at compile time; I'm not sure why GP is suggesting returning false if you don't want types to be compared. By default structs are not comparable. If you opt-in to the standard PartialEq implementation using the `derive` annotation[1], it will only allow a struct to be compared for equality with other structs of the same type. You can choose to add implementations to compare against other types[2].
