// mutation_set_pickup_point.go
|
|
//
|
|
// Registers the SetPickupPoint mutation using the generic mutation registry.
|
|
//
|
|
// Semantics (mirrors original switch-based implementation):
|
|
// - Locate the delivery with Id == payload.DeliveryId
|
|
// - Set (or overwrite) its PickupPoint with the provided data
|
|
// - Does NOT alter pricing or taxes (so no totals recalculation required)
|
|
//
|
|
// Validation / Error Handling:
|
|
// - If payload is nil -> error
|
|
// - If DeliveryId not found -> error
|
|
//
|
|
// Concurrency:
|
|
// - Relies on the existing expectation that higher-level mutation routing
|
|
// serializes Apply() calls per grain; if stricter guarantees are needed,
|
|
// a delivery-level lock could be introduced later.
|
|
//
|
|
// Future Extensions:
|
|
// - Validate pickup point fields (country code, zip format, etc.)
|
|
// - Track history / audit of pickup point changes
|
|
// - Trigger delivery price adjustments (which would then require WithTotals()).
