> By using modern C++ features it is possible to enforce a Rust-like model of ownership, without any memory management

C++ fans always claim this is possible, but can never say how to determine whether any given codebase follows their rules, or give examples of e.g. popular open-source libraries that follow that approach. So I've stopped believing in it, personally.

I find that claim extremely dubious. The problems of such code are very rarely due to not having clear directions on any local ownership relationship, and lifetimes are not actually visible in C++ in any case.
