Bytenum

Bytenum is a rust derive macro that creates a try_from<T> implementation for an enum with only unit variants. All types supported by #[repr(T)] are supported by bytenum.

Usage

Add this to your Cargo.toml:

toml bytenum = "0.1.9"

Example:

```rust use bytenum::Bytenum;

[derive(Bytenum, Debug, PartialEq, Copy, Clone)]

[repr(u16)]

enum Color { Red = 0x04, Green = 0x15, Blue = 0x34, }

fn main() -> Result<(), Box> { asserteq!(Color::Red, Color::tryfrom(0x04)?); asserteq!(Color::Green, Color::tryfrom(0x15)?); asserteq!(Color::Blue, Color::tryfrom(0x34)?); Ok(()) } ```
