Struct oxrdf::QuadRef

pub struct QuadRef<'a> {
    pub subject: SubjectRef<'a>,
    pub predicate: NamedNodeRef<'a>,
    pub object: TermRef<'a>,
    pub graph_name: GraphNameRef<'a>,
}

A borrowed triple in an RDF dataset.

The default string formatter is returning an N-Quads compatible representation:

use oxrdf::{QuadRef, NamedNodeRef};

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

Fields

subject: SubjectRef<'a>

The subject of this triple.

predicate: NamedNodeRef<'a>

The predicate of this triple.

object: TermRef<'a>

The object of this triple.

graph_name: GraphNameRef<'a>

The name of the RDF graph in which the triple is.

Implementations

impl<'a> QuadRef<'a>

pub fn new( subject: impl Into<SubjectRef<'a>>, predicate: impl Into<NamedNodeRef<'a>>, object: impl Into<TermRef<'a>>, graph_name: impl Into<GraphNameRef<'a>> ) -> Self

Builds an RDF triple in an RDF dataset.

pub fn into_owned(self) -> Quad

Trait Implementations

impl<'a> Clone for QuadRef<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for QuadRef<'a>

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

Formats the value using the given formatter.

impl Display for QuadRef<'_>

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

Formats the value using the given formatter.

impl<'a> From<&'a Quad> for QuadRef<'a>

fn from(quad: &'a Quad) -> Self

Converts to this type from the input type.

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

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

Converts to this type from the input type.

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

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

Converts to this type from the input type.

impl<'a> Hash for QuadRef<'a>

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

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<QuadRef<'a>> for QuadRef<'a>

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

This method tests for self and other values to be equal, and is used by ==.

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

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