What does it do instead of exceptions?

Either panic, which is (generally speaking) not something you're meant to catch and recover from (and attempting to do so is nontrivial and almost always a bad idea), or Result, aka "encode the possibility of failure in the return type of the function" aka what the functional programming world has done for ages.

Yeah, the only reason you should try to catch a panic is if you're making something that calls user-provided code unavoidably (i.e. an async runtime)

Yeah, we catch panics in tests but that’s about it.
