For stability reasons, we probably don't want to expose future
combinator types from the
futures_util
crate in public APIs. If wewere to change which combinators are used to implement these futures, or
if
futures_util
made breaking changes, this could cause API breakage.This branch wraps all publicly exposed
futures_util
types in theopaque_future!
macro added in #508, to wrap them in newtypes that hidetheir internal details. This way, we can change these futures' internals
whenever we like.
