Exceptions are often a better way to handle errors than returning them as values. We argue that traditional exceptions provide better user and developer experience, and show that they even result in faster execution.
I think the author of the article just haven’t understood how to use the ? operator yet, and don’t think they deserve being called “utterly incompetent” for it. Whether something is a monad or not is not necessarily something a programmer should have to think about on a daily basis IMO.
I just think of rust errors as a tagged enum with either a value or an error. And the ? operator as syntax sugar for returning if something was an error. IMO that simple understanding is sufficient to do error handling in Rust. I don’t think we should gatekeep programming behind some intellectual barrier of whether or not you understand category theory. I certainly don’t understand what a monad is, but I can still write working software and do error handling without unwraps.
I was making a shared library at work and was recently asked to start throwing exceptions, because the users wouldn’t care to check my returned error and just continue with the empty returned data.
Well, now they will most probably have an empty catch block and continue doing what they did before.
