Examples

use async_graphql::*;

struct QueryRoot;

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

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

#[async_std::main]
async fn main() {
    let schema = Schema::new(QueryRoot, EmptyMutation, EmptySubscription);
    assert_eq!(schema.execute("{ value1 }").await.unwrap().cache_control, CacheControl { public: true, max_age: 30 });
    assert_eq!(schema.execute("{ value2 }").await.unwrap().cache_control, CacheControl { public: false, max_age: 60 });
    assert_eq!(schema.execute("{ value1 value2 }").await.unwrap().cache_control, CacheControl { public: false, max_age: 30 });
}
