Why is stuff written in rust always promoted as "written in rust" like its some magic thing?

It carries some weight, very roughly in the direction of formal verification. Since (assuming there isn't any unsafe), a specific class of bugs are guaranteed to not happen.

However, this repo seems like it uses quite a bit of unsafe, by their own admission.

There's a lot of unsafe in this at least. hard to be both safe and fast.

From the README:
