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.
Anyone know what real time means here? Does it mean that sleeping a thread is more accurate (as in the thread is resumed at the correct time after calling sleep)? Or is there an API that implements some functionality for something that should run in real time?
