# derive-step

## requires nightly!!

a very simple derive macro for the unstable standard library [Step](https://doc.rust-lang.org/stable/std/iter/trait.Step.html) trait.

currently, this only works on unit enums like the (equally unstable) [AsciiChar](https://doc.rust-lang.org/stable/std/ascii/enum.Char.html).

see the tests directory for usage examples!
