But panics in rust are pretty much exceptions though?
The differences are they are actually meant to be used for exceptional situations ("assert violated => there's a bug in this program" or "out of memory, catastrophic runtime situation") and they are not typed (rather, the panic holds a type erased payload).
Other than that, it performs unwinding without UB, and is catchable[0]. I'm not seeing the technical difference?

- layer8 4y agoYou’re probably right now that I’ve read up on it, I wasn’t previously aware of catch_unwind.
- dureuill 4y agoGlad to be of service. Note that the idiomatic error handling in rust is still Result based rather than panic/catch_unwind based. Nevertheless a long living application like, e.g., a webserver will catch panics coming from its subtasks (e.g., its request handlers) via catch_unwind
