pub enum EdgeDirection {
Out,
In,
Both,
}Expand description
Direction filter for directed edge lookups.
Historical edge queries were bidirectional (source = ? OR target = ?).
EdgeDirection restricts a lookup to outgoing or incoming edges only —
required for inherently directed graphs such as legal citation networks
(A cites B) or document wikilinks/backlinks.
Both is the default and preserves the historical behavior.
Variants§
Out
Out-edges only: the node is the edge source.
In
In-edges only: the node is the edge target.
Both
Both directions (default; preserves the historical bidirectional behavior).
