Triple

flams_math_archives::triple_store::sparql::spargebra::term

Struct Triple

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

Available on crate feature rdf only.

Expand description

An owned RDF triple.

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

use oxrdf::{NamedNode, Triple};

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: NamedOrBlankNode

The subject of this triple.

§predicate: NamedNode

The predicate of this triple.

§object: Term
