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 = "0.1.0"

Example:

```rust use enum2str::EnumStr;

[derive(EnumStr)]

enum Object { Simple,

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

}

[derive(EnumStr)]

enum Color { Red, Green, SlateGray, }

[derive(EnumStr)]

enum Shape { Circle, }

[test]

fn main() -> Result<(), Box> { asserteq!(Object::Simple.tostring(), "Simple"); asserteq!( Object::Complex(Color::Green, Shape::Circle).tostring(), "Color: Green. Shape: Circle." ); asserteq!(Color::Red.tostring(), "Red"); asserteq!(Color::SlateGray.tostring(), "SlateGray"); Ok(()) } ```
