  1. std::unique_ptr does not have runtime overhead. std::unique_ptr is essentially Rust’s Box. std::shared_ptr is reference counted like Rust’s Arc. Comparing apples to apples, C++ is essentially the same to Rust in this regard.

  3.  @khatdubell , unique_ptr<T> with non-default deleter is analogous to Box<Wrapped<T>> where Wrapped has custom Drop.
