inttype-enum

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

Auto implement From<enum> for inttype, and TryFrom<inttype> for enum. if one(only one) variant is tagged with #[default], then From<inttype> for enum will be implemented

Usage examples:

toml [dependencies] inttype-enum = "0.1"

```rust

[derive(IntType)]

[repr(u8)]

enum Cmd { Connect = 1, Bind = 2, Udp = 3, }

let conn: u8 = Cmd::Connect.into(); assert!(matches!(Cmd::tryfrom(conn), Ok(Cmd::Connect))); assert!(matches!(Cmd::tryfrom(0), Err(_))); ```

```rust

[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)); ```
