It's funny. First you write something in something that might be quite memory-safe (Rust), then you combine it with something that throws all memory-safety guarantees out of the window (x86 assembly). I guess practicality beats purity.

If the assembly isn't doing any memory allocation and just works on data that is already there... it isn't that unsafe and not too hard to verify that it is correct. Rust is still doing it's job in that it is reducing the breath of areas that need alot of eyes.
