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,
|
|
|
|
|
|
}
|
|
|
|
|
|
```
