Enum Neigh 

Source 
pub enum Neigh<S>
where
    S: NeighsRDF,
{
    Direct {
        p: S::IRI,
        o: S::Term,
    },
    Inverse {
        s: S::Subject,
        p: S::IRI,
    },
}
Expand description

Represents a single neighborhood relationship in an RDF graph.

A neighborhood relationship can be either a direct connection (outgoing arc) or an inverse connection (incoming arc) relative to a focus node.

§Type Parameters

  • S - The RDF graph type implementing NeighsRDF

§Variants

  • Direct: An outgoing relationship where the focus node is the subject
  • Inverse: An incoming relationship where the focus node is the object

Variants§

§

Direct

A direct (outgoing) relationship from the focus node.

Represents a triple pattern: (focusNode, p, o) where the focus node is the subject, p is the predicate, and o is the object.

§Fields

  • p - The predicate IRI of the relationship
  • o - The object term that the predicate points to

Fields

§p: S::IRI
§o: S::Term
§

Inverse

An inverse (incoming) relationship to the focus node.

Represents a triple pattern: (s, p, focusNode) where s is the subject, p is the predicate, and the focus node is the object.

§Fields

  • s - The subject that has this relationship to the focus node
  • p - The predicate IRI of the relationship

Fields

§s: S::Subject
§p: S::IRI

Implementations§

Source§

impl<S> Neigh<S>
where S: NeighsRDF,

Source

pub fn direct(pred: S::IRI, object: S::Term) -> Neigh<S>

Creates a direct (outgoing) neighborhood relationship.

Constructs a neighborhood representing an outgoing arc from a focus node via the specified predicate to the given object.

§Arguments
  • pred - The predicate IRI of the relationship
  • object - The object term that the predicate points to
Source

pub fn inverse(pred: S::IRI, subject: S::Subject) -> Neigh<S>

Creates an inverse (incoming) neighborhood relationship.

Constructs a neighborhood representing an incoming arc to a focus node via the specified predicate from the given subject.

§Arguments
  • pred - The predicate IRI of the relationship
  • subject - The subject that has this relationship to the focus node
