`enum-display` is a crate for implementing `std::fmt::Display` on enum variants with macros.

# Simple Example

```rust

use enum_display::EnumDisplay;

#[derive(EnumDisplay)]

enum Color {

  Red,

  Green,

  Blue,

}

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

assert_eq!(Color::Green.to_string(), "Green");

assert_eq!(Color::Blue.to_string(), "Blue");

```

# Example With Custom Case Transform

Any case from [convert_case](https://docs.rs/convert_case/latest/convert_case/) is supported.

```rust

use enum_display::EnumDisplay;

#[derive(EnumDisplay)]

#[enum_display(case = "Kebab")]

enum Message {

    HelloGreeting { name: String },

}

assert_eq!(Message::HelloGreeting { name: "Alice".to_string() }.to_string(), "hello-greeting");

```
