Panics in Rust are for logic errors that can't be meaningfully recovered from. You can easily convert an error state into a panic, by using .unwrap() or .expect(), or pass the error back to the caller via the '?' syntax. Rust does have a "recover"-like facility that can catch a panic, but it's intended for exceptional use; it also has no effect when panics are configured (at the whole-program level) to abort the program immediately.

Yes, that matches my understanding. In Go, panics can also be used for recoverable errors, if you so choose. In Rust you can catch_unwind() which is similar to Go’s recover(), and the big difference is that (1) it may not work depending on how your project is configured, and (2) its use is very strongly discouraged.

In theory, Go is the same way, but Go does a lot less to prevent panics, limit them to very specific circumstances, mitigate their effects, or limit unexpected failure modes.
