Nope, that's not a class, that's a struct and a module with functions. Any method called as obj.foo(5) is really just a function foo with a hidden argument foo(obj, 5). Rust makes this architecture explicit with its structs and trait impls separated - and no OOP in sight.

Classes, on the other hand, are not structs with functions. More like black boxes whose contents can be swapped out at any moment. OOP is about hiding implementation and infinite extensibility.

I do not know Rust but this seems an implementation detail, like if I would make the Vector.normalize function static and then pass the this as an argument. Sometimes this pattern with static function works well too. My classes also have private methods and sometimes even private static pure functions. Anyway you Rust people do whatever you want and call them whatever you want , I will call a struct with methods a class.
