Struct Quad 

pub struct Quad {
    pub subject: RdfSubject,
    pub predicate: RdfPredicate,
    pub object: RdfObject,
    pub graph: Option<NamedNode>,
}

RDF quad (triple + named graph)

Fields

subject: RdfSubject

Subject

predicate: RdfPredicate

Predicate

object: RdfObject

Object

graph: Option<NamedNode>

Named graph (None = default graph)

Implementations

impl Quad

pub fn new( subject: RdfSubject, predicate: RdfPredicate, object: RdfObject, graph: Option<NamedNode>, ) -> Self

Create a new quad

pub fn from_triple(triple: Triple) -> Self

Create a quad from a triple (default graph)

pub fn as_triple(&self) -> Triple

Get the triple part (without graph)

Trait Implementations

impl Clone for Quad

fn clone(&self) -> Quad

Returns a duplicate 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.
