     * The model is constrained when the first solution is built.
     * Any shipments not performed on a route are implicitly skipped in the first
     * solution, but they may be performed in successive solutions.
     * The solution must satisfy some basic validity assumptions:
     *   * for all routes, `vehicle_index` must be in range and not be duplicated.
     *   * for all visits, `shipment_index` and `visit_request_index` must be
     *     in range.
     *   * a shipment may only be referenced on one route.
     *   * the pickup of a pickup-delivery shipment must be performed before
     *     the delivery.
     *   * no more than one pickup alternative or delivery alternative of
     *     a shipment may be performed.
     *   * for all routes, times are increasing (i.e., `vehicle_start_time
     *     &lt;= visits[0].start_time &lt;= visits[1].start_time ...
     *     &lt;= vehicle_end_time`).
     *   * a shipment may only be performed on a vehicle that is allowed. A
     *     vehicle is allowed if
     *     [Shipment.allowed_vehicle_indices][google.cloud.optimization.v1.Shipment.allowed_vehicle_indices]
     *     is empty or its `vehicle_index` is included in
     *     [Shipment.allowed_vehicle_indices][google.cloud.optimization.v1.Shipment.allowed_vehicle_indices].
     * If the injected solution is not feasible, a validation error is not
     * necessarily returned and an error indicating infeasibility may be returned
     * instead.
