Yes. You can call Rust code from C:

You can do the same to call it from D. I have never done it, but
I did call Rust from Ruby at one point.
Does the GC run regardless of if it's used? Someone alluded to
this earlier, but I just wanted clarity. If I write nogc code,
will the GC just stand by idly? Or, is there an option to
completely turn it off?
If you don't allocate with the GC, the GC doesn't run. Code
marked @nogc is guaranteed not to cause the GC to run. You can
turn the GC off using GC.disable, but there are extreme cases in
which it can still run.
