You're not really giving up OOP with Rust, traits give you interface abstraction which is most of what you're getting with C++. As I write more C++ I find myself using less classes and more structs + functions that let me decouple my code and data.

If anything I would say Rust is a tad more multi-paradigm due to its really strong functional roots(Sum types!) and nicer treatment of lambdas(no alloc like in std::function).

Maybe a bit off-topic, but I just want to clarify - lambdas only include dynamic allocation if you convert them to an std::function, right? I was under the impression that 'auto f = []{...}' did no heap allocation, but converting to an std::function could, depending on the size of the closure.

Yup your on the mark, it leads to some interesting scenarios where you can't easily refactor code without either introducing template hell or taking the hit for std::function.
