///
/// A length of time. Duration is a specialization of the FHIR Quantity
/// datatype constrained to represent an elapsed span of time, expressed as a
/// numeric value together with a coded unit drawn from the UCUM time-unit
/// value set (for example seconds, minutes, hours, or days). It is used
/// throughout FHIR R5 wherever a period of elapsed time is needed, such as a
/// medication administration window, an appointment length, or a study
/// interval.
///
/// # Examples
///
/// ```
/// use fhir::r5::types::duration::Duration;
///
/// let value = Duration::default();
/// let json = ::serde_json::to_value(&value).unwrap();
/// let back: Duration = ::serde_json::from_value(json).unwrap();
/// assert_eq!(value, back);
/// ```
