# Enum Extend

Provide Derive Macro for Plain Enum

## Example

derive `EnumStr` can impl Some Traits about `str` and `String`

1. `pub const as_str(&self) -> &'static str`
2. `AsRef<str>`
3. `ToString`
4. `From<&str>`
5. `From<&String>`
6. `From<String>`

`From<Str>` Maybe **Panic!!!**

```rust
use enumex::EnumStr;

#[derive(EnumStr)]
enum Animal {
    Cat,
    Dog,
}
```
