fn triples_matching<S, P, O>( &self, subject: S, predicate: P, object: O, ) -> Result<impl Iterator<Item = Self::Triple>, SRDFSparqlError>
Note to implementors: this function needs to retrieve all the triples of
the graph. Therefore, for use-cases where the graph is large, this
function should be implemented in a way that it does not retrieve all
triples at once. As an example, for implementations of SPARQL, this
function should be implemented to retrieve just the triples that match
the given subject, predicate and object.

fn outgoing_arcs_from_list( &self, subject: &Self::Subject, preds: &[Self::IRI], ) -> Result<OutgoingArcsFromList<Self>, Self::Err>
get outgoing arcs from a
node
taking into account only a controlled list of preds
It returns a HashMap with the outgoing arcs and their values and a list of the predicates that have values and are not in the controlled list.Source§impl Rdf for SRDFSparql
