Also - Rust code can directly link to C++ code and vice-versa. If you're an existing C++ shop with a big codebase (say, a large game engine), you don't have to "rewrite it in rust". You can just start building new parts in rust. Like, if you're building a new audio subsystem, you can do "just that subsystem" in rust, and expose an interface for the rest of the legacy engine code to use.
