Here's a discussion on actix-web and panic handlers: https://github.com/actix/actix-web/issues/1501

Some technical limits, a lot of cultural opposition. While it is possible to have a panic handler, it's generally viewed as a bad idea. Not everything is UnwindSafe, there are limits to how much a panic handler can do, concerns about memory leaks.
