Providing such a range is not a burden on the T type as any such range is acceptable and only PartialOrd is required so it can be satisfied with an incomparable value n with n n In rust lang rfcs 1320 this RFC was amended to change the RangeInclusive type from a struct with a finished field to an enum 1192 inclusive ranges The Rust RFC Book GitHub Pages. Can construct a range comprised of types that are Copy you should be able to copy the range If you were unaware this is how tuples work which you can see at play below fnassert copy T std marker Copy fnmain assert copy usize usize Fine assert copy Vec usize usize Uh oh For and range The for in construct can be used to iterate through an Iterator One of the easiest ways to create an iterator is to use the range notation a b This yields values from a inclusive to b exclusive in steps of one Let s write FizzBuzz using for instead of while
