There is no Rust tooling that tells you if your unsafe code is shit or not. If there was you wouldn't need the unsafe stuff at all.

The Actix web stuff was the maintainer using unsafe code to increase performance (iirc, it was a long time ago) in what was the most popular rust web frameworks at the time. It has since declined and been supplanted by other projects but the push was mainly a web framework shouldn't need so much unsafe. They eventually ceded the project to another maintainer and went off to work on something else.

Maybe my memory is hazy on it, but yeah that's the exact drama I remember.

Fuzzing can help with that. But it’s not only applicable to Rust.

For Actix web he was using “unsafe” to increase performance. That doesn’t mean the code written was unsafe… The Rust community was turning to a cult on this topic when perfectly experienced C++ can write code would need the unsafe in Rust when they perfectly know the code isn’t. It’s good for the community to push people to avoid to use unsafe but not to that extend of drama and bullying…
