Struct oxrdf::Triple

pub struct Triple {
    pub subject: Subject,
    pub predicate: NamedNode,
    pub object: Term,
}

An owned RDF triple.

The default string formatter is returning an N-Triples, Turtle, and SPARQL compatible representation:

use oxrdf::{Triple, NamedNode};

assert_eq!(
    "<http://example.com/s> <http://example.com/p> <http://example.com/o>",
    Triple {
        subject: NamedNode::new("http://example.com/s")?.into(),
        predicate: NamedNode::new("http://example.com/p")?,
        object: NamedNode::new("http://example.com/o")?.into(),
    }.to_string()
);

Fields

subject: Subject

The subject of this triple.

predicate: NamedNode

The predicate of this triple.

object: Term

The object of this triple.
