/// A request to supply a diet, formula feeding (enteral) or oral nutritional
/// supplement to a patient/resident.
///
/// A NutritionOrder captures the details of what a patient should be fed and
/// is the primary FHIR R5 resource used to request nutrition services. It
/// spans three complementary areas of nutrition care: oral diets (including
/// diet types, texture modifications, fluid consistency, and nutrient limits),
/// oral nutritional supplements, and enteral (tube) feeding formulas with
/// their additives, caloric density, route of administration, and delivery
/// schedules. Each order records its ordering context through status and
/// intent codes, the subject who requires the nutrition, the associated
/// encounter, the requested date and time, and the orderer and performers.
/// To support safe fulfillment it can also reference the patient's food and
/// nutrition-related allergies and intolerances, along with food preference
/// and exclusion modifiers.
///
/// In clinical workflows a NutritionOrder is authored by a clinician or
/// dietitian and communicated to dietary or nursing services so that meals,
/// supplements, or tube feedings are prepared and delivered according to the
/// patient's needs. As a request-pattern resource it participates in
/// order-management flows and can be based on protocols or plans and grouped
/// with related orders.
///
/// # See also
///
/// The subject is commonly a [`Patient`](crate::r5::resources::patient::Patient),
/// referenced together with the visit [`Encounter`](crate::r5::resources::encounter::Encounter).
/// Dietary safety draws on the patient's
/// [`AllergyIntolerance`](crate::r5::resources::allergy_intolerance::AllergyIntolerance)
/// records. Coded values such as diet types and food modifiers use
/// [`CodeableConcept`](crate::r5::types::CodeableConcept), while resource
/// links use [`Reference`](crate::r5::types::Reference).
///
/// # Examples

/// use fhir::r5::resources::nutrition_order::NutritionOrder;

/// let json = ::serde_json::to_value(&value).unwrap();
/// let back: NutritionOrder = ::serde_json::from_value(json).unwrap();
