Expand description
Represents a GraphQL container object.
This helper trait allows the type to call resolve_container
on itself in its
OutputType::resolve
implementation.
Required methods
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,
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 async_graphql::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: Send + Sync,
fn collect_all_fields<'a>(
&'a self,
ctx: &ContextSelectionSet<'a>,
fields: &mut Fields<'a>
) -> ServerResult<()> where
Self: 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.
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,
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.
