/// A measured amount (or an amount that can potentially be measured). Note that
/// measured amounts include amounts that are not precisely quantified, including
/// amounts involving arbitrary units and floating currencies. The `Count`
/// datatype is a specialization used to represent a whole number of discrete
/// items, and in FHIR R5 it carries the same structural fields as `Quantity`
/// (value, comparator, unit, system, and code).
///
/// # Examples
///
/// ```
/// use fhir::r5::types::count::Count;
///
/// let value = Count::default();
/// let json = ::serde_json::to_value(&value).unwrap();
/// let back: Count = ::serde_json::from_value(json).unwrap();
/// assert_eq!(value, back);
/// ```
