Enum FocusSource 

pub enum FocusSource {
    SubjectsOf(NamedNode),
    ObjectsOf(NamedNode),
    Node(Term),
    PathToConst {
        path: Path,
        target: Term,
    },
    ScanFilter {
        path: Path,
        qualifier: ShapeId,
    },
    Sparql(SparqlTarget),
}

How to enumerate the focus nodes of a statement.

Variants

SubjectsOf(NamedNode)

sh:targetSubjectsOf p — subjects of (·, p, ·).

ObjectsOf(NamedNode)

sh:targetObjectsOf p — objects of (·, p, ·).

Node(Term)

sh:targetNode c — a single node.

PathToConst

Path selector with a constant qualifier (e.g. class targets): the focus set is pred(target, path) — nodes reaching target along path.

Fields

path: Path

target: Term

ScanFilter

General path selector: scan candidate nodes, keep those with a path-successor satisfying qualifier.

Fields

path: Path

qualifier: ShapeId

Sparql(SparqlTarget)

Parsed and canonicalized SPARQL target.
