I'm less certain about this one. If people are used to working with raw pointers in Rust this is fine, but i wonder if we can do some other kind of comparison to not have to introduce offset in these docs. I don't anticipate people looking at CString with a solid understanding of Rust pointers. This is frequently an entry point into FFI, so readers may potentially only have a cursory understanding of pointers.

I'm not sure what else would fit here, let me know if you have any ideas. Or if you'd prefer the offset lines to be removed, I can do that too

Now that I think back on it, this is probably good as-is. I was thinking of something like slice::from_raw_parts and comparing against a byte-string, but that risks losing focus from showing off the actual function being documented. If we come up with something better, we can always send another PR.
