pub struct QuadWriter<W: Write> { /* private fields */ }
Expand description
Allows writing triples.
Could be built using a DatasetSerializer
.
Do not forget to run the finish
method to properly write the last bytes of the file.
use oxigraph::io::{DatasetFormat, DatasetSerializer};
use oxigraph::model::*;
let mut buffer = Vec::new();
let mut serializer = DatasetSerializer::from_format(DatasetFormat::NQuads).quad_writer(&mut buffer);
serializer.write(&Quad {
subject: NamedNode::new("http://example.com/s")?.into(),
predicate: NamedNode::new("http://example.com/p")?,
object: NamedNode::new("http://example.com/o")?.into(),
graph_name: NamedNode::new("http://example.com/g")?.into(),
})?;
serializer.finish()?;
assert_eq!(buffer.as_slice(), "<http://example.com/s> <http://example.com/p> <http://example.com/o> <http://example.com/g> .\n".as_bytes());
