Module io 

Utilities to read and write RDF graphs and datasets using OxRDF I/O.

The entry points of this module are the two RdfParser and RdfSerializer structs.

Usage example converting a Turtle file to a N-Triples file:

use oxigraph::io::{RdfFormat, RdfParser, RdfSerializer};

let turtle_file = "@base <http://example.com/> .
@prefix schema: <http://schema.org/> .
<foo> a schema:Person ;
    schema:name \"Foo\" .
<bar> a schema:Person ;
    schema:name \"Bar\" .";

let ntriples_file = "<http://example.com/foo> <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://schema.org/Person> .
<http://example.com/foo> <http://schema.org/name> \"Foo\" .
<http://example.com/bar> <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://schema.org/Person> .
<http://example.com/bar> <http://schema.org/name> \"Bar\" .
";

let mut serializer = RdfSerializer::from_format(RdfFormat::NTriples).for_writer(Vec::new());
for quad in RdfParser::from_format(RdfFormat::Turtle).for_reader(turtle_file.as_bytes()) {
    serializer.serialize_quad(&quad.unwrap()).unwrap();
}
assert_eq!(serializer.finish().unwrap(), ntriples_file.as_bytes());
