//! Extension

//! Extension Type: Optional Extension Element - found in all resources.

/// Optional Extension Element - found in all resources.
///
/// Every element in a FHIR resource or datatype may include one or more
/// `Extension` child elements. Extensions provide a standardized mechanism for
/// representing additional information that is not part of the base definition
/// of the element, while preserving interoperability. Each extension is
/// identified by a `url` and carries a single value drawn from the FHIR
/// `value[x]` choice, and extensions may themselves be nested to build complex
/// structures.
///
/// # Examples
///
/// ```
/// use fhir::r5::types::extension::Extension;
///
/// let value = Extension::default();
/// let json = ::serde_json::to_value(&value).unwrap();
/// let back: Extension = ::serde_json::from_value(json).unwrap();
/// assert_eq!(value, back);
/// ```
