That's a neat way to get corrupted state in your application, especially when users of said language don't realize that their language has exceptions.

I wrote this recently about Go, but it equally applies to any Rust application that tries to recover from a panic.

I don't think this is right. The process will crash, and the Supervision strategy you are using will determine what happens from there. This is what the BEAM is all about. The thing with NIFs is that they can crash the entire VM if they error.
Erlang's (Elixirs) error management approach is actually "Let it crash"

This is based on the acknowledgment that if you have a large number of longer running processes at some point something will crash anyway, so you may quite as well be good at managing crashes ;-)

Yes, but that's not Rust's error management strategy. Most Rust code isn't written with recovery from panics in mind, so it can have unintended consequences if you catch panics and then retry.
