Cache control values

Examples

use async_graphql::*;

struct Query;

#[Object(cache_control(max_age = 60))]
impl Query {
    #[graphql(cache_control(max_age = 30))]
    async fn value1(&self) -> i32 {
        0
    }

    #[graphql(cache_control(private))]
    async fn value2(&self) -> i32 {
        0
    }
}

let schema = Schema::new(Query, EmptyMutation, EmptySubscription);
assert_eq!(
    schema
        .execute("{ value1 }")
        .await
        .into_result()
        .unwrap()
        .cache_control,
    CacheControl {
        public: true,
        max_age: 30
    }
);
assert_eq!(
    schema
        .execute("{ value2 }")
        .await
        .into_result()
        .unwrap()
        .cache_control,
    CacheControl {
        public: false,
        max_age: 60
    }
);
assert_eq!(
    schema
        .execute("{ value1 value2 }")
        .await
        .into_result()
        .unwrap()
        .cache_control,
    CacheControl {
        public: false,
        max_age: 30
    }
);
