Implementations

impl QueryOptions

pub fn with_default_graph_as_union(self) -> Self

Consider the union of all graphs in the store as the default graph

pub fn with_default_graph(
    self,
    default_graph_name: impl Into<GraphName>
) -> Self

Adds a graph to the set of graphs considered by the SPARQL query as the queried dataset default graph. It overrides the FROM and FROM NAMED elements of the evaluated query.

pub fn with_named_graph(
    self,
    named_graph_name: impl Into<NamedOrBlankNode>
) -> Self

Adds a named graph to the set of graphs considered by the SPARQL query as the queried dataset named graphs. It overrides the FROM and FROM NAMED elements of the evaluated query.

pub fn with_service_handler(
    self,
    service_handler: impl ServiceHandler + 'static
) -> Self

Use a given ServiceHandler to execute SPARQL 1.1 Federated Query SERVICE calls.
