In terms of Rust guarantees with C* code; the Rust parts of the code will be fine. Which means if you have an issue, you can easily isolate it to the C* code (probably doesn't help a lot). You can probably isolate things if you use IPC (I believe there is a few crates for that), but it wouldn't prevent the result from being wrong, only from unsafe behaviour stomping the address space. You could likely avoid copy if you relied on SHM for larger data patterns. On the other hand, integrating Rust and C* isn't terribly hard, there is automated tools that generate bindings for C/Rust so you don't really have to think about it much other than unpacking the unsafe data from C*.
