Because these are General Purpose languages you can do the same things, but the contrast here is what's provided in the box and how it is used idiomatically, because in practice that's what gets used, and that's what I explained above.

You can write C++ style OOP hierarchy code in Rust but that's not idiomatic, and you can write Rust style explicit dynamic dispatch in C++ but again it isn't idiomatic.
