Struct GroundTriple

pub struct GroundTriple {
    pub subject: GroundSubject,
    pub predicate: NamedNode,
    pub object: GroundTerm,
}

A RDF triple without blank nodes.

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

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

assert_eq!(
    "<http://example.com/s> <http://example.com/p> <http://example.com/o>",
    GroundTriple {
        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: GroundSubject

predicate: NamedNode

object: GroundTerm

Trait Implementations

impl Clone for GroundTriple

fn clone(&self) -> GroundTriple

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GroundTriple

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

Formats the value using the given formatter.

impl Display for GroundTriple

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

Formats the value using the given formatter.

impl From<GroundTriple> for GroundSubject

fn from(triple: GroundTriple) -> Self

Converts to this type from the input type.

impl From<GroundTriple> for GroundTerm

fn from(triple: GroundTriple) -> Self

Converts to this type from the input type.

impl From<GroundTriple> for GroundTriplePattern

fn from(triple: GroundTriple) -> Self

Converts to this type from the input type.

impl Hash for GroundTriple

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 GroundTriple

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

type Error = ()

The type returned in the event of a conversion error.

fn try_from(triple: Triple) -> Result<Self, Self::Error>

Performs the conversion.
