GraphSelector

oxirs_arq::executor::dataset

Enum GraphSelector 

Source 
pub enum GraphSelector {
    DefaultGraph,
    Named(NamedNode),
}
Expand description

Selects which graph(s) a triple-pattern lookup targets within a Dataset.

This mirrors the SPARQL RDF-dataset distinction between the single active default graph and an individually addressed named graph. It deliberately does not offer an “all graphs / union” mode, because unioning every graph for a plain pattern is exactly the semantic bug this abstraction exists to prevent (see Dataset::find_triples).

Variants§

§

DefaultGraph

The dataset’s active default graph.

§

Named(NamedNode)

A single named graph addressed by its IRI (e.g. GRAPH <iri> { ... }).
