enum2repr

enum2repr is a rust derive macro that creates conversion methods to map between a value and an enum. Numeric types supported by #[repr(T)] are supported by enum2repr.

Usage

Add this to your Cargo.toml:

toml enum2repr = "0.1.12"

Example:

```rust use enum2repr::EnumRepr;

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

[repr(u16)]

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

[test]

fn convertvariants() { asserteq!(Ok(Color::Red), Color::tryfrom(0x04)); asserteq!(Ok(Color::Green), Color::tryfrom(0x15)); asserteq!(Ok(Color::Blue), Color::try_from(0x34)); }

[test]

fn convertvariantsback() { asserteq!(u16::tryfrom(Color::Red), Ok(0x04)); asserteq!(u16::tryfrom(Color::Green), Ok(0x15)); asserteq!(u16::tryfrom(Color::Blue), Ok(0x34)); } ```
