Struct rio_api::model::Quad

pub struct Quad<'a> {
    pub subject: Subject<'a>,
    pub predicate: NamedNode<'a>,
    pub object: Term<'a>,
    pub graph_name: Option<GraphName<'a>>,
}

A RDF triple in a RDF dataset.

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

Trait Implementations

impl<'a> Clone for Quad<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Quad<'a>

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

Formats the value using the given formatter.

impl<'a> Display for Quad<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for Quad<'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<Quad<'a>> for Quad<'a>

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