Struct EntityEvent 

pub struct EntityEvent {
    pub entity: String,
    pub event_kind: EventKind,
    pub old: Option<Value>,
    pub new: Option<Value>,
    pub timestamp: DateTime<Utc>,
}

Entity event with old and new row data.

Represents a mutation event from the database. Used by the observer pipeline to dispatch to after:mutation triggers asynchronously.

Dispatch Semantics

• Fire after mutation completes (mutation response already sent)
• Async dispatch: doesn’t block mutation response
• Failure doesn’t affect mutation (error logged only)
• Execution order: in declaration order from schema

Fields

event_kind: EventKind

Kind of mutation.

old: Option<Value>

Old row data (None for Insert).

new: Option<Value>

New row data (None for Delete).

timestamp: DateTime<Utc>
