Why not use `getopt()` which already exists in libc?
(Or even `getopt_long()` if you're Linux/glibc-only? Author mentions not supporting Windows, but is unclear whether non-Linux Unices, e.g. *BSD, are intended target platforms.)
If you're trying to implement as much in Rust as possible, keeping an important part of the codebase in C code feels like the wrong decision, in my opinion.
