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

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

If the field was not found returns None.

Provided Methods

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.

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

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