I guess someone complained about memory safety and they intend to rewrite hepatitis in Rust.
Not everything has to be rewritten in Rust! Hepatitis is a virus, C is much better suited for that kind of project, Rust is for fungal diseases, not viruses.
Wouldn't measles be the better (immune) memory safety joke?

If I say I'm going to borrow a needle and just look at it, you should just trust me. If I use it, I make sure to sterilize it before returning it.
