# Examples

```rust
use async_graphql::*;

#[derive(Enum, Copy, Clone, Eq, PartialEq)]
enum MyEnum {
    A,
    #[graphql(name = "b")] B,
}

struct Query {
    value1: MyEnum,
    value2: MyEnum,
}

#[Object]
impl Query {
    /// value1
    async fn value1(&self) -> MyEnum {
        self.value1
    }

    /// value2
    async fn value2(&self) -> MyEnum {
        self.value2
    }
}

# tokio::runtime::Runtime::new().unwrap().block_on(async move {
let schema = Schema::new(Query{ value1: MyEnum::A, value2: MyEnum::B }, EmptyMutation, EmptySubscription);
let res = schema.execute("{ value1 value2 }").await.into_result().unwrap().data;
assert_eq!(res, value!({ "value1": "A", "value2": "b" }));
# });
