//! A `Reference` is a lightweight link from one resource to another resource, either by URL/id or by logical identifier.

/// A reference from one resource to another, used wherever one resource needs to point to
/// another (e.g. a `Patient` referenced from an `Observation`). The reference may be a literal
/// relative or absolute URL, or it may carry only a business `identifier` and/or a human-readable
/// `display` string when no resolvable URL is available.
///
/// # Examples
///
/// ```
/// use fhir::r5::types::reference::Reference;
///
/// let value = Reference::default();
/// let json = ::serde_json::to_value(&value).unwrap();
/// let back: Reference = ::serde_json::from_value(json).unwrap();
/// assert_eq!(value, back);
/// ```
