Struct EmployeeChangeEvent 

pub struct EmployeeChangeEvent {
    pub employee_id: String,
    pub event_date: NaiveDate,
    pub event_type: EmployeeEventType,
    pub old_value: Option<String>,
    pub new_value: Option<String>,
    pub effective_date: NaiveDate,
}

A single entry in an employee’s change history.

Captures point-in-time changes to an employee record (hire, promotion, salary adjustment, transfer, or termination). The old_value / new_value fields carry a string representation of the changed attribute (e.g., job level code, salary amount, department name) to keep the schema generic and easy to consume from downstream analytics.

Fields

employee_id: String

Employee this event belongs to.

event_date: NaiveDate

Calendar date on which the event was recorded in the HR system.

event_type: EmployeeEventType

Type of HR event.

old_value: Option<String>

Previous value of the changed attribute (None for the Hired event).

new_value: Option<String>

New value of the changed attribute.

effective_date: NaiveDate

Date from which the change is effective (may differ from event_date for retroactive or future-dated transactions).
