README
A derive macro that adds a impl From<u8> to any enum.
If the number of items is bigger than u8::MAX, it will use u16, then u32 if bigger than u16::MAX.
Example:
use stupid_from_num::FromNum;
#[derive(FromNum)]
enum Example {
Zero,
One,
Two,
}
assert_eq!(Example::Zero.into(), 0);
assert_eq!(Example::One.into(), 1);
assert_eq!(Example::Two.into(), 2);
