pub struct Quad {
pub subject: Subject,
pub predicate: NamedNode,
pub object: Term,
pub graph_name: GraphName,
}
Expand description
An owned triple in an RDF dataset.
The default string formatter is returning an N-Quads compatible representation:
use oxrdf::{Quad, NamedNode};
assert_eq!(
"<http://example.com/s> <http://example.com/p> <http://example.com/o> <http://example.com/g>",
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(),
}.to_string()
);
Fields§
§subject: Subject
The subject of this triple.
predicate: NamedNode
The predicate of this triple.
object: Term
The object of this triple.
graph_name: GraphName
The name of the RDF graph in which the triple is.
