use crateIdentifiable;
/// A trait indicating that an entity class has a status property
///
/// This trait provides access and setting functionality for the status of
/// domain objects, where the status is represented using a generic
/// parameter, allowing different enum types to represent the status.
///
/// # Type Parameters
///
/// * `S` - The type of the status, usually an enum type
///
/// # Example
///
/// ```rust
/// use qubit_mixin::{WithStatus, Identifiable};
///
/// #[derive(Debug, Clone, Copy, PartialEq, Eq)]
/// enum OrderStatus {
/// Pending,
/// Paid,
/// Shipped,
/// Completed,
/// Cancelled,
/// }
///
/// struct Order {
/// id: Option<i64>,
/// status: OrderStatus,
/// }
///
/// impl Identifiable for Order {
/// fn id(&self) -> Option<i64> {
/// self.id
/// }
///
/// fn set_id(&mut self, id: Option<i64>) {
/// self.id = id;
/// }
/// }
///
/// impl WithStatus<OrderStatus> for Order {
/// fn status(&self) -> OrderStatus {
/// self.status
/// }
///
/// fn set_status(&mut self, status: OrderStatus) {
/// self.status = status;
/// }
/// }
///
/// let mut order = Order {
/// id: Some(1),
/// status: OrderStatus::Pending,
/// };
/// assert_eq!(order.status(), OrderStatus::Pending);
///
/// order.set_status(OrderStatus::Paid);
/// assert_eq!(order.status(), OrderStatus::Paid);
/// ```
