Read more, Consumes an iterator, creating two collections from it. A sum type is a type that at any given time may contain any of one or more types, where which type a given value has may be inspected at run time (a tagged union). Its goal is to provide a fast, practical, concurrent language with zero-cost abstractions and strong memory safety. /// vec!
