/// Substance
///
/// A homogeneous material with a definite composition. This resource captures
/// substances used in healthcare, whether as a specific physical instance (such
/// as a particular batch or package) or as a general kind of substance. It
/// records the substance code, category, quantity, expiry, and its constituent
/// ingredients along with their relative amounts.
///
/// Substances are used across many clinical and administrative workflows: as the
/// active or inactive ingredients that make up a medication, as allergens or
/// irritants referenced from an allergy or intolerance record, as specimens or
/// samples handled by a laboratory, or as raw materials tracked through supply
/// and manufacturing processes. A `Substance` instance may represent either a
/// specific physical package or lot (an "instance") or a general category of
/// material (a "kind"), as indicated by the `instance` field. The `code` field
/// identifies what the substance is, typically using a standard terminology
/// such as SNOMED CT or a national drug/substance coding system, while
/// `ingredient` describes the substance's own composition when it is itself a
/// mixture or compound.
///
/// # See also
///
/// Substances are commonly referenced from medication and clinical resources
/// such as `Medication`, `MedicationKnowledge`, and `AllergyIntolerance`, and
/// use shared data types including [`CodeableConcept`](crate::r5::types::CodeableConcept),
/// [`CodeableReference`](crate::r5::types::CodeableReference), and
/// [`Quantity`](crate::r5::types::Quantity) to describe classification and amount.
///
/// # Examples
///
/// ```
/// use fhir::r5::resources::substance::Substance;
///
/// let value = Substance::default();
/// let json = ::serde_json::to_value(&value).unwrap();
/// let back: Substance = ::serde_json::from_value(json).unwrap();
/// assert_eq!(value, back);
