# 枚举(Enum)

定义一个枚举相当简单，直接给出一个例子。

**Async-graphql会自动把枚举项的名称转换为GraphQL标准的大写加下划线形式，你也可以用`name`属性自已定义名称。**

```rust
#[Enum(desc = "One of the films in the Star Wars Trilogy")]
pub enum Episode {
    #[item(desc = "Released in 1977.")]
    NewHope,

    #[item(desc = "Released in 1980.")]
    Empire,

    // rename to `AAA`
    #[item(name="AAA", desc = "Released in 1983.")]
    Jedi,
}
```
