pub fn for_writer<W: Write>(self, writer: W) -> WriterRdfXmlSerializer<W>

Serializes a RDF/XML file to a Write implementation.

This writer does unbuffered writes.

use oxrdf::{LiteralRef, NamedNodeRef, TripleRef};
use oxrdf::vocab::rdf;
use oxrdfxml::RdfXmlSerializer;

let mut serializer = RdfXmlSerializer::new().with_prefix("schema", "http://schema.org/")?.for_writer(Vec::new());
serializer.serialize_triple(TripleRef::new(
    NamedNodeRef::new("http://example.com#me")?,
    rdf::TYPE,
    NamedNodeRef::new("http://schema.org/Person")?,
))?;
serializer.serialize_triple(TripleRef::new(
    NamedNodeRef::new("http://example.com#me")?,
    NamedNodeRef::new("http://schema.org/name")?,
    LiteralRef::new_language_tagged_literal_unchecked("Foo Bar", "en"),
))?;
