Struct Relation 

pub struct Relation {
    pub relation_type: String,
    pub id: Value,
    pub input: ThingRef,
    pub output: ThingRef,
    pub data: HashMap<String, Value>,
}

A database-agnostic graph relation/edge.

This type represents a relationship between two nodes (records) in graph databases like Neo4j and SurrealDB. It contains the relation type, IDs for both endpoints, and optional properties on the relation itself.

Fields

relation_type: String

The relation type (table name in SurrealDB terms)

id: Value

The relation’s own ID

input: ThingRef

The source node reference (table name + id)

output: ThingRef

The target node reference (table name + id)

data: HashMap<String, Value>

Properties on the relation itself

Implementations

impl Relation

pub fn new( relation_type: impl Into<String>, id: Value, input: ThingRef, output: ThingRef, data: HashMap<String, Value>, ) -> Self

Create a new relation.
