/// A time period defined by a start and an end date and, optionally, time.
///
/// `Period` is used throughout FHIR resources and other datatypes to express a
/// span of time, such as when a coverage was in effect, when an address was
/// valid, or when a condition was active. Either `start` or `end` (or both)
/// may be present; an absent `start` means the period began at an unknown
/// time in the past, and an absent `end` means the period is ongoing or open.
///
/// # Examples
///
/// ```
/// use fhir::r5::types::period::Period;
///
/// let value = Period::default();
/// let json = ::serde_json::to_value(&value).unwrap();
/// let back: Period = ::serde_json::from_value(json).unwrap();
/// assert_eq!(value, back);
/// ```
