Struct EdgeHeader 

pub struct EdgeHeader {
    pub src: VertexId,
    pub dst: VertexId,
    pub edge_type: String,
    pub ranking: i64,
}

Lightweight read-only view of the query-visible edge identity.

Carries the (src, dst, edge_type, ranking) tuple with no property map and no storage-internal table-scoped identifier. Scan sources emit this when the planner proves no downstream consumer needs the boxed entity; any property or endpoint-label resolution against it is a planner miss and must surface as an explicit error, never a silent null.

Fields

src: VertexId

dst: VertexId

edge_type: String

ranking: i64
