Struct Edge 

Source 
pub struct Edge {
    pub source_node_id: String,
    pub target_node_id: String,
    pub relationship_name: String,
    pub description: Option<String>,
}
Expand description

Edge in a knowledge graph.

Represents a relationship between two nodes. Edges are akin to Wikipedia links - they connect related concepts.

§Fields

  • source_node_id - ID of the source node
  • target_node_id - ID of the target node
  • relationship_name - Type of relationship (use snake_case, e.g., “works_at”)
  • description - Concrete one-sentence fact expressed by this edge

Fields§

§source_node_id: String

ID of the source node

§target_node_id: String

ID of the target node

§relationship_name: String

Type of relationship (snake_case, e.g., “works_at”, “founded”, “located_in”)

§description: Option<String>

Concrete one-sentence fact expressed by this edge, using endpoint names. Mirrors Python KnowledgeGraph.Edge.description (data_models.py:62-71). Becomes the edge_text graph-edge property, feeding EdgeType + Triplet embeddings. Optional because older/custom outputs may omit it.
