Struct Triple 

pub struct Triple {
    pub subject: NamedOrBlankNode,
    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::{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

The object of this triple.

Implementations

impl Triple

pub fn new( subject: impl Into<NamedOrBlankNode>, predicate: impl Into<NamedNode>, object: impl Into<Term>, ) -> Self

Builds an RDF triple.

pub fn from_terms( subject: impl Into<Term>, predicate: impl Into<Term>, object: impl Into<Term>, ) -> Result<Self, TryFromTermError>

Builds an RDF triple from Terms.

Returns a TryFromTermError error if the generated triple would be ill-formed.

pub fn in_graph(self, graph_name: impl Into<GraphName>) -> Quad

Encodes that this triple is in an RDF dataset.

pub fn as_ref(&self) -> TripleRef<'_>

impl PartialEq for Triple

fn eq(&self, other: &Triple) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
