/// Risk of harmful or undesirable, physiological response which is unique to an
/// individual and associated with exposure to a substance.
///
/// AllergyIntolerance records a clinical assessment of a propensity, or a
/// potential risk to an individual, of an adverse reaction upon future exposure
/// to the specified substance, or class of substance. It is used in FHIR R5 to
/// capture the allergy or intolerance itself along with any reaction events that
/// have been observed and the participants who asserted or recorded the record.
///
/// Clinically, this resource supports decision support and safety checking (for
/// example, prescribing or order-entry alerts), and it distinguishes between an
/// allergy (an immune-mediated response) and an intolerance (a non-immune
/// adverse reaction), while also allowing the underlying mechanism to be left
/// unspecified when it is not known. A single resource instance describes one
/// propensity for a subject; each observed occurrence of a reaction is recorded
/// as a repeating `reaction` component with details such as manifestation,
/// severity, and onset, and the individuals who reported or verified the
/// assessment can be captured via the `participant` component.
///
/// # Related resources
///
/// - [`Patient`](crate::r5::resources::patient::Patient) — the subject for whom
/// the allergy or intolerance is recorded, referenced via the `patient` field.
/// - [`CodeableConcept`](crate::r5::types::CodeableConcept) — used for coded
/// values such as `clinical_status`, `verification_status`, `type`, and `code`.
/// - `Encounter` — optionally referenced via `encounter` to indicate the
/// clinical context in which the allergy or intolerance was asserted.
/// - `Condition` and `Observation` — related clinical resources that may also
/// reference or corroborate an allergy or intolerance assessment.
///
/// # Examples
///
/// ```
/// use fhir::r5::resources::allergy_intolerance::AllergyIntolerance;
///
/// let value = AllergyIntolerance::default();
/// let json = ::serde_json::to_value(&value).unwrap();
/// let back: AllergyIntolerance = ::serde_json::from_value(json).unwrap();
/// assert_eq!(value, back);
