Struct DatasetSerializer

pub struct DatasetSerializer { /* private fields */ }

👎Deprecated since 0.4.0: use RdfSerializer instead

A serializer for RDF graph serialization formats.

It currently supports the following formats:

• N-Quads (DatasetFormat::NQuads)
• TriG (DatasetFormat::TriG)

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());

Implementations

pub fn from_format(format: DatasetFormat) -> Self

Builds a serializer for the given format

pub fn quad_writer<W: Write>(self, writer: W) -> QuadWriter<W>

Returns a QuadWriter allowing writing triples into the given Write implementation
