Struct Quad

pub struct Quad {
    pub subject: Subject,
    pub predicate: NamedNode,
    pub object: Term,
    pub graph_name: GraphName,
}

A RDF triple in an RDF dataset.

The default string formatter is returning a N-Quads representation.

use spargebra::term::{NamedNode, Quad};

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

Trait Implementations

impl Clone for Quad

fn clone(&self) -> Quad

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Quad

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

Formats the value using the given formatter.

impl Display for Quad

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

Formats the value using the given formatter.

impl Hash for Quad

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 PartialEq for Quad

fn eq(&self, other: &Quad) -> 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.

impl TryFrom<Quad> for GroundQuad

type Error = ()

fn try_from(quad: Quad) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<QuadPattern> for Quad

type Error = ()

The type returned in the event of a conversion error.

fn try_from(quad: QuadPattern) -> Result<Self, Self::Error>

Performs the conversion.
