use rio_api::formatter::TriplesFormatter;
use rio_api::model::{NamedNode, Triple};

let mut formatter = NTriplesFormatter::new(Vec::default());
formatter.format(&Triple {
    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()
})?;
let _ntriples = formatter.finish();
