Struct Edge 

pub struct Edge {
    pub src: VertexId,
    pub dst: VertexId,
    pub edge_type: String,
    pub ranking: i64,
    pub props: HashMap<Arc<str>, Value>,
}

Represents an edge in the graph, similar to Nebula’s Edge structure

Edges are uniquely identified by (src, dst, edge_type, ranking). The internal edge ID is managed by the storage layer and is not exposed to users.

Fields

src: VertexId

dst: VertexId

edge_type: String

ranking: i64

props: HashMap<Arc<str>, Value>
