Struct async_graphql::Connection

pub struct Connection<T, E: ObjectType + Sync + Send = EmptyEdgeFields> { /* fields omitted */ }

Connection type

Connection is the result of a query for DataSource, If the T type is OutputValueType, you can return the value as a field function directly, otherwise you can use the Connection::map function to convert to a type that implements OutputValueType. E is an extension object type that extends the edge fields.
