Right, I never mentioned that I am a decently experienced C developer, so of course I got my fair share of buffer overflows and race conditions :)

I have also learned some Rust recently, I find a nice language and quite pleasant to work with. I understand its benefits.

But still, Git is already a mature tool (one may say "finished"). Lots of bugs have been found and fixed. And if more are found, sure it will be easier to fix them in the C code, rather than rewriting in Rust? Unless the end goal is to rewrite the whole thing in Rust piece by piece, solving hidden memory bugs along the way.
