It's currently unclear if Rust can interop with C++ with high fidelity. For example https://docs.rs/moveit/latest/moveit/ and https://github.com/google/crubit/blob/main/rs_bindings_from_... provide functionality to use non-trivially relocatable C++ types from Rust.

Bit hard to follow but as far as I can tell those are pinning the C++ types and wrapping them in some other object that allows a move constructor to be called on them to move them to some other pinned location.

It still doesn't let you natively move them, and if you have to wrap them in something you may as well just wrap them in `Box<>` and not move them, which is what cxx does.

I guess maybe it makes a difference for passing things into existing C++ interfaces?

Anyway it looks insanely complicated.
