Struct GraphSerializer

pub struct GraphSerializer { /* private fields */ }

👎Deprecated since 0.4.0: use RdfSerializer instead

A serializer for RDF graph serialization formats.

It currently supports the following formats:

• N-Triples (GraphFormat::NTriples)
• Turtle (GraphFormat::Turtle)
• RDF/XML (GraphFormat::RdfXml)

use oxigraph::io::{GraphFormat, GraphSerializer};
use oxigraph::model::*;

let mut buffer = Vec::new();
let mut serializer =
    GraphSerializer::from_format(GraphFormat::NTriples).triple_writer(&mut buffer);
serializer.write(&Triple {
    subject: NamedNode::new("http://example.com/s")?.into(),
    predicate: NamedNode::new("http://example.com/p")?,
    object: NamedNode::new("http://example.com/o")?.into(),
})?;
serializer.finish()?;

assert_eq!(
    buffer.as_slice(),
    "<http://example.com/s> <http://example.com/p> <http://example.com/o> .\n".as_bytes()
);
