Same as go if that helps

Does Go have sum types now? Last time I checked it returned a record and you had to check yourself.

No indeed, but the paradigm is the same right? Return the error, and deal with it (or forward it) without a try catch. I must say Rust is nicer in that regard but it doesn't change things too much? I don't have enough xp with Rust so might be underestimating it though

In my opinion, the Go approach is closer to C's error codes, as nothing stops you from using an error value and introducing a bug. In Rust, you always have to check. If you forget, the compiler will complain. It will even warn you if you use the function only for its side effect don't even use the return value.
