Struct NQuadsSerializer

Source

pub struct NQuadsSerializer {}

Expand description

A N-Quads serializer.

Support for N-Quads-star is available behind the rdf-star feature.

use oxrdf::{NamedNodeRef, QuadRef};
use oxrdf::vocab::rdf;
use oxttl::NQuadsSerializer;

let mut serializer = NQuadsSerializer::new().for_writer(Vec::new());
serializer.serialize_quad(QuadRef::new(
    NamedNodeRef::new("http://example.com#me")?,
    rdf::TYPE,
    NamedNodeRef::new("http://schema.org/Person")?,
    NamedNodeRef::new("http://example.com")?,
))?;
assert_eq!(
    b"<http://example.com#me> <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://schema.org/Person> <http://example.com> .\n",
    serializer.finish().as_slice()
);
