/// A StructureMap describes a map of relationships between two or more
/// structures that can be used to transform instance data from one form to
/// another. It defines the rules, groups, and transforms used by a FHIR
/// mapping engine to convert a source instance into a target instance. This
/// resource is central to the FHIR Mapping Language and is commonly used in
/// implementation guides to specify structural data transformations.
///
/// A StructureMap is typically authored using the FHIR Mapping Language
/// (`.map` syntax) and then compiled into this resource form, or it can be
/// authored directly as structured content. It is most often used to convert
/// data between different versions of FHIR, between FHIR and non-FHIR formats
/// (such as HL7 v2 or CDA), or between a source implementation guide profile
/// and a target profile. Each map references one or more source
/// `StructureDefinition`s via the `structure` element, organizes its
/// transformation logic into named `group` elements, and within each group
/// defines `rule`s that read from `source` elements and write to `target`
/// elements, optionally invoking transforms or dependent rules/groups. A
/// conformant FHIR mapping engine executes the map to produce the
/// transformed output instance.
///
/// # Related resources
///
/// A StructureMap's `structure` elements point to
/// [`StructureDefinition`](crate::r5::resources::structure_definition::StructureDefinition)s
/// that describe the shape of the source and target data, and its
/// `jurisdiction` uses
/// [`CodeableConcept`](crate::r5::types::CodeableConcept) values. Maps that
/// transform clinical data commonly operate on resources such as
/// [`Patient`](crate::r5::resources::patient::Patient) or
/// [`Observation`](crate::r5::resources::observation::Observation),
/// converting instances of one profile or format into another.
///
/// # Examples
///
/// ```ignore
/// use fhir::r5::resources::structure_map::StructureMap;
///
/// let value = StructureMap::default();
/// let json = ::serde_json::to_value(&value).unwrap();
/// let back: StructureMap = ::serde_json::from_value(json).unwrap();
/// assert_eq!(value, back);
