True. You could write it in C or asm too, and it would be about as simple. But there's still a difference that if they weren't all primitive (and you can't always rely that they will be), you'll know it won't work straight away in Rust, whereas in the others you need to walk every data type involved to make sure ownership is clear (or rely on a garbage collector to save you).
