(Tip of my fingers) Library with a macro to create an enum from a range
I know I could write (and have written) this enum myself by hand. I don't want to use a newtype around u8 or something like that because I want the static guarantees of an enum — plus I'm using EnumMap to create statically-allocated maps with enum keys, so I'm hoping whatever this library was will play nicely with it.
