C++ inheritance doesn't map well to Rust's trait system for one. I think this is an ongoing issue within the `bindgen` community, but I don't know much beyond that. Suffice to say, some concepts in C++ do not map well to Rust and so FFI can be hairy in some instances. On instance of this becoming a complication would be in the GTK+ world with the Rust bindings to GObject. There's some really good articles about their adventures in that realm you could find.
