Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Draft

Draft - not yet submitted

PendingApproval

Pending approval

Approved

Approved, ready to send

Sent

Sent to supplier

Acknowledged

Acknowledged by supplier

PartiallyReceived

Partially received

Received

Fully received

Completed

Completed/closed

Cancelled

Cancelled

OnHold

On hold

Implementations

impl PurchaseOrderStatus

pub fn can_transition_to(self, next: PurchaseOrderStatus) -> bool

Check if a status transition is allowed.

Models the purchase order lifecycle: draft → pending_approval → approved → sent → acknowledged → partially_received → received → completed.

OnHold is reachable from PendingApproval, Approved, Sent, and Acknowledged, and can be released back to any of those states. Cancellation is allowed from any non-terminal state before the PO is fully received. Completed and Cancelled are terminal.

Note: the SQLite store (stateset-db::sqlite::purchase_orders) only enforces the draft-only guard on submit_for_approval; other transition methods should consult this guard.

pub const fn is_terminal(self) -> bool

Returns true if this status is terminal (no further transitions).
