Crate inttype_enum

Converts an [enum] into an inttype, and try to convert it back

Usage example:

#[derive(IntType)]
#[repr(u8)]
enum Cmd {
    Connect = 1,
    Bind = 2,
    Udp = 3,
}
 
let conn: u8 = Cmd::Connect.into();
assert!(matches!(Cmd::try_from(conn), Ok(Cmd::Connect)));
assert!(matches!(Cmd::try_from(0), Err(_)));
 
#[derive(IntType)]
#[repr(u8)]
enum Method {
    A = 1,
    B = 2,
    #[default]
    C = 3,
}
assert!(matches!(1.into(), Method::A));
assert!(matches!(0.into(), Method::C));
