Struct GeneralizedQuad

pub struct GeneralizedQuad<'a> {
    pub subject: GeneralizedTerm<'a>,
    pub predicate: GeneralizedTerm<'a>,
    pub object: GeneralizedTerm<'a>,
    pub graph_name: Option<GeneralizedTerm<'a>>,
}

A generalized RDF triple in a RDF dataset.

The default string formatter is returning a SPARQL representation.

use rio_api::model::{GeneralizedQuad, Variable};

assert_eq!(
    "?s ?p ?o .",
    GeneralizedQuad {
        subject: Variable { name: "s" }.into(),
        predicate: Variable { name: "p" }.into(),
        object: Variable { name: "o" }.into(),
        graph_name: None,
    }.to_string()
);

assert_eq!(
    "GRAPH ?g { ?s ?p ?o .}",
    GeneralizedQuad {
        subject: Variable { name: "s" }.into(),
        predicate: Variable { name: "p" }.into(),
        object: Variable { name: "o" }.into(),
        graph_name: Some(Variable { name: "g" }.into()),
    }.to_string()
);

Using it requires to enable the generalized feature.

Trait Implementations

impl<'a> Clone for GeneralizedQuad<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for GeneralizedQuad<'a>

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

Formats the value using the given formatter.

impl<'a> Display for GeneralizedQuad<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for GeneralizedQuad<'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 for GeneralizedQuad<'a>

fn eq(&self, other: &GeneralizedQuad<'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.
