Struct WriterQuadSerializer 

pub struct WriterQuadSerializer<W>
where
    W: Write,
{ /* private fields */ }

Serializes quads or triples to a Write implementation.

Can be built using RdfSerializer::for_writer.

Do not forget to run the finish method to properly write the last bytes of the file.

This writer does unbuffered writes. You might want to use BufWriter to avoid that.

use oxrdfio::{RdfFormat, RdfSerializer};
use oxrdf::{Quad, NamedNode};

let mut serializer = RdfSerializer::from_format(RdfFormat::NQuads).for_writer(Vec::new());
serializer.serialize_quad(&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(),
})?;
assert_eq!(serializer.finish()?, b"<http://example.com/s> <http://example.com/p> <http://example.com/o> <http://example.com/g> .\n");

Implementations

impl<W> WriterQuadSerializer<W>

where W: Write,

pub fn serialize_quad<'a>( &mut self, quad: impl Into<QuadRef<'a>>, ) -> Result<(), Error>

Serializes a QuadRef

pub fn serialize_triple<'a>( &mut self, triple: impl Into<TripleRef<'a>>, ) -> Result<(), Error>

Serializes a TripleRef

pub fn finish(self) -> Result<W, Error>

Writes the last bytes of the file

Note that this function does not flush the writer. You need to do that if you are using a BufWriter.
