Struct rio_api::model::GeneralizedQuad

pub struct GeneralizedQuad<'a> {
    pub subject: GeneralizedTerm<'a>,
    pub predicate: GeneralizedTerm<'a>,
    pub object: GeneralizedTerm<'a>,
    pub graph_name: Option<GeneralizedTerm<'a>>,
}

A generalized RDF triple in a RDF dataset.

The default string formatter is returning a SPARQL representation.

use rio_api::model::{GeneralizedQuad, Variable};

assert_eq!(
    "?s ?p ?o .",
    GeneralizedQuad {
        subject: Variable { name: "s" }.into(),
        predicate: Variable { name: "p" }.into(),
        object: Variable { name: "o" }.into(),
        graph_name: None,
    }.to_string()
);

assert_eq!(
    "GRAPH ?g { ?s ?p ?o .}",
    GeneralizedQuad {
        subject: Variable { name: "s" }.into(),
        predicate: Variable { name: "p" }.into(),
        object: Variable { name: "o" }.into(),
        graph_name: Some(Variable { name: "g" }.into()),
    }.to_string()
);

Using it requires to enable the generalized feature.
