Struct Link 

pub struct Link {
    pub id: Uuid,
    pub tenant_id: Uuid,
    pub link_type: String,
    pub source: EntityReference,
    pub target: EntityReference,
    pub metadata: Option<Value>,
    pub created_at: DateTime<Utc>,
    pub updated_at: DateTime<Utc>,
}

A polymorphic link between two entities

Links are completely agnostic to the types of entities they connect. This allows the link system to work with any entity types without modification.

Fields

id: Uuid

Unique identifier for this link

tenant_id: Uuid

Tenant ID for multi-tenant isolation

link_type: String

The type of relationship (e.g., “owner”, “driver”, “worker”)

CRITICAL: This is a String, not an enum, to support any relationship type without modifying the core framework

source: EntityReference

The source entity in this relationship

target: EntityReference

The target entity in this relationship

metadata: Option<Value>

Optional metadata for the relationship

Can store additional context like:

• start_date / end_date for temporal relationships
• role for employment relationships
• permission level for access relationships

created_at: DateTime<Utc>

When this link was created

updated_at: DateTime<Utc>

When this link was last updated
