Migrate to edition 2021 #967

Open Philippe-Cholet opened 4 months ago

Philippe-Cholet commented 4 months ago

I noted 5 months ago that edition 2021 requires rustc 1.56+ so it's now possible. Is there any reason to not update?

I added some marginal changes:

@jswrenn I remember your https://github.com/rust-itertools/itertools/pull/780#discussion_r1352664093 where you prefered ControlFlow over Result, I replaced some, left some aside for now. Can you elaborate on the reason?

I remember your #780 (comment) where you prefered ControlFlow over Result, I replaced some, left some aside for now. Can you elaborate on the reason?

Result::Err denotes "something went wrong"; ControlFlow::Break doesn't. Favor ControlFlow when we're trying to encode conditional iteration without judgement about error-ness, and favor Result when you're specifically dealing with an early return due to error.

@Philippe-Cholet is this good to merge?
