> Unlike Go's, rust's panics do not actually, universally, get "propagated up the call stack until they reach a "catch point", where they can be handled by the programmer". There's a compiler flag which can be "unwind" or "abort". In the former case (the default), panics can be caught and recovered from. In the latter case, the program gets hard-stopped on the spot.

There are Rust libraries (e.g. salsa, used in rust-analyzer itself) that use unwinding internally for non-local control flow and won't work with unwinding disabled.
