Required Methods§

Source

fn has(&self, id: &RelationInstanceId) -> bool

Returns true, if an relation of the given type exists which starts at the given outbound entity and ends at the given inbound entity.

Source

fn get(&self, id: &RelationInstanceId) -> Option<ReactiveRelation>

Returns the ReactiveRelation with the given type_name, which starts at the given outbound entity and ends at the given inbound entity.

Source

fn get_by_outbound_entity( &self, outbound_entity_id: Uuid, ) -> Vec<ReactiveRelation>

Returns all reactive relation instances of the given outbound entity instance.

Source
