Struct TripleRef 

pub struct TripleRef<'a> {
    pub subject: NamedOrBlankNodeRef<'a>,
    pub predicate: NamedNodeRef<'a>,
    pub object: TermRef<'a>,
}

A borrowed RDF triple.

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

use oxrdf::{NamedNodeRef, TripleRef};

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

Fields

subject: NamedOrBlankNodeRef<'a>

The subject of this triple.

predicate: NamedNodeRef<'a>

The predicate of this triple.

object: TermRef<'a>

The object of this triple.

Implementations

impl<'a> TripleRef<'a>

pub fn new( subject: impl Into<NamedOrBlankNodeRef<'a>>, predicate: impl Into<NamedNodeRef<'a>>, object: impl Into<TermRef<'a>>, ) -> TripleRef<'a>

Builds an RDF triple.

pub fn in_graph(self, graph_name: impl Into<GraphNameRef<'a>>) -> QuadRef<'a>

Encodes that this triple is in an RDF dataset.

pub fn into_owned(self) -> Triple

Trait Implementations

impl<'a> Clone for TripleRef<'a>

fn clone(&self) -> TripleRef<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for TripleRef<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for TripleRef<'_>

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'a> From<&'a Triple> for TripleRef<'a>

fn from(triple: &'a Triple) -> TripleRef<'a>

Converts to this type from the input type.

impl<'a> From<QuadRef<'a>> for TripleRef<'a>

fn from(quad: QuadRef<'a>) -> TripleRef<'a>

Converts to this type from the input type.

impl<'a> From<TripleRef<'a>> for Triple

fn from(triple: TripleRef<'a>) -> Triple

Converts to this type from the input type.

impl<'a> Hash for TripleRef<'a>

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> PartialEq for TripleRef<'a>

fn eq(&self, other: &TripleRef<'a>) -> bool

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

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
