    Curious to hear what in Rust could be more easily solved with OOP! I think one reason for rust not using OOP is because they want to minimize dynamic dispatch and keep it explicit where it happens, because it’s a language that gives you very fine grained control of resource usage, kinda similar to how you have to be explicit about copying for most types. Most trait calls are static dispatch unless you have a Box::<dyn SomeTrait>

      IMO rust does use OOP styles all over the place. OOP does not mean dynamic dispatch or inheritance - that is just what older popular languages used. Note that static dispatch and monomorphization (where the compiler generates a method for each type at compile time rather than using a runtime lookup) give you a lot of the benefits of dynamic dispatch at the cost of binary size in favor of runtime checks and performance.

      And other aspects of OOP, like encapsulation, data abstractions and polymorphism are easily achievable in rust and often are. Just look at any object from the std library - they are all essentially written in an OOP style. Such as Vec or File - hidden internal state with traits that you can swap them around with other parts that make sense. The only thing it really likes - like Go lang (which claims to be an OOP style language) is inheritance.

      And the only reason rust is not seen as or describes itself as an OOP language is because it does not force the OOP style on you. But instead lets you program in more of a functional or procedural style if you want to. You can pick the best methodology to solve the problem you have at hand rather than trying to fir everything into a single style.

      But that does not make it bad at OOP style.

        I’m using “OOP” more in the sense that is described in the article, but that is a fair perspective on rust and OOP. It is a term with a lot of different interpretations after all.
