Struct async_graphql::CacheControl

pub struct CacheControl {
    pub public: bool,
    pub max_age: usize,
}

Cache control values

Examples

use async_graphql::*;

struct QueryRoot;

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

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

tokio::runtime::Runtime::new().unwrap().block_on(async {
    let schema = Schema::new(QueryRoot, 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 });
});

Fields

public: bool

Scope is public, default is true.

max_age: usize
