use rio_turtle::NQuadsFormatter;
use rio_api::formatter::QuadsFormatter;
use rio_api::model::{NamedNode, Quad};

let mut formatter = NQuadsFormatter::new(Vec::default());
formatter.format(&Quad {
    subject: NamedNode { iri: "http://example.com/foo" }.into(),
    predicate: NamedNode { iri: "http://www.w3.org/1999/02/22-rdf-syntax-ns#type" }.into(),
    object: NamedNode { iri: "http://schema.org/Person" }.into(),
    graph_name: Some(NamedNode { iri: "http://example.com/" }.into())
})?;
let _nquads = formatter.finish();
