A GraphQL container.

This helper trait allows the type to call resolve_container on itself in its OutputValueType::resolve implementation.

Required methods

#[must_use]fn resolve_field<'life0, 'life1, 'life2, 'async_trait>(
    &'life0 self,
    ctx: &'life1 Context<'life2>
) -> Pin<Box<dyn Future<Output = ServerResult<Option<Value>>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    'life1: 'async_trait,
    'life2: 'async_trait,
    Self: 'async_trait, 

Resolves a field value and outputs it as a json value serde_json::Value.

If the field was not found returns None.

Provided methods

fn collect_all_fields<'a>(
    &'a self,
    ctx: &ContextSelectionSet<'a>,
    fields: &mut Fields<'a>
) -> ServerResult<()> where
    Self: Sized + Send + Sync, 

Collect all the fields of the container that are queried in the selection set.

Objects do not have to override this, but interfaces and unions must call it on their internal type.

#[must_use]fn find_entity<'life0, 'life1, 'life2, 'life3, 'async_trait>(
    &'life0 self,
    __arg1: &'life1 Context<'life2>,
    _params: &'life3 Value
) -> Pin<Box<dyn Future<Output = ServerResult<Option<Value>>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    'life1: 'async_trait,
    'life2: 'async_trait,
    'life3: 'async_trait,
    Self: Sync + 'async_trait, 

Find the GraphQL entity with the given name from the parameter.

Objects should override this in case they are the query root.
