enum2str

enum2str is a rust derive macro that creates a Display impl for enums. This is useful for strongly typing composable sets of strings.

Usage

Add this to your Cargo.toml:

toml enum2str = "0.1.3"

Example:

```rust use enum2str::EnumStr;

[derive(EnumStr)]

enum Object { Generic(String),

#[enum2str("Color: {}. Shape: {}.")]
Complex(Color, Shape),

}

[derive(EnumStr)]

enum Color { #[enum2str("Burgundy")] Red, Green, }

[derive(EnumStr)]

enum Shape { Circle, }

fn main() { asserteq!(Color::Green.tostring(), "Green");

assert_eq!(Color::Red.to_string(), "Burgundy");

assert_eq!(Object::Generic("Hello!".to_string()).to_string(), "Hello!");

assert_eq!(
    Object::Complex(Color::Green, Shape::Circle).to_string(),
    "Color: Green. Shape: Circle."
);

} ```
