OxTTL

Oxttl is a set of parsers and serializers for Turtle, TriG, N-Triples, N-Quads and N3.

Support for RDF 1.2 is available behind the rdf-12 feature for all languages but N3.

It is designed as a low level parser compatible with both synchronous and asynchronous I/O.

Usage example counting the number of people in a Turtle file:

use oxrdf::{NamedNodeRef, vocab::rdf};
use oxttl::TurtleParser;

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

let schema_person = NamedNodeRef::new("http://schema.org/Person").unwrap();
let mut count = 0;
for triple in TurtleParser::new().for_reader(file.as_ref()) {
    let triple = triple.unwrap();
    if triple.predicate == rdf::TYPE && triple.object == schema_person.into() {
        count += 1;
    }
}
assert_eq!(2, count);
