Derive Macro ReprFrom

#[derive(ReprFrom)]
{
    // Attributes available to this derive:
    #[enumeration]
}

Derives From<CLikeEnum> for the primitive representation specified in #[repr(...)].

Examples

#[derive(Debug, Clone, Copy, PartialEq, Eq, enum_utils::ReprFrom)]
#[repr(u8)]
pub enum Direction {
    North = 1,
    East,
    South,
    West
}

use Direction::*;
assert_eq!(1u8, North.into());
assert_eq!(4u8, West.into());

This macro only works on C-like enums.

#[derive(Debug, Clone,  enum_utils::TryFromRepr)]
#[repr(u8)]
pub enum Letter {
    A,
    B,
    Other(u8),
}
