And yet, a Rust Option (or really any option) can just be viewed as a list of one or zero elements. https://rust-unofficial.github.io/patterns/idioms/option-ite... In fact, in Haskell, operating on an option conditionally has the exact same functor as a list: `map`. So what am I to do, with an iterator? It's conflicting advice! An if is a for for an option. |
