A Simpler Way to See Results

Result is Rust's error handling type that is often discussed in the same (or similar) breath as Option, but it feels... scarier. But in this video, I'll argue that that relationship with Option is a useful piece to focus on; they are isomorphic in certain circumstances, and even when they're not, you can think of them as coexisting on a continuum. Then we'll talk about the dreaded/beloved question mark, FromIterator/collect, and some Error stuff. Special guest appearances from anyhow, thiserror, derive_more, and boxed Error trait objects; Haskell do-notation, applicative functors, and the first official time I've ever said 'monad' on this channel; and more.
