/// A record of a request for service such as diagnostic investigations,
/// treatments, or operations to be performed.
///
/// The ServiceRequest resource is used to place an order or request for a
/// service to be performed on or for a patient, group, device, or location.
/// Typical services include diagnostic tests, imaging studies, laboratory work,
/// referrals, counseling, and procedures. In FHIR R5 it carries the requested
/// code, subject, timing, requester, performer, and supporting clinical context,
/// and can be linked to fulfilling results and provenance.
///
/// Clinically, a ServiceRequest represents the intent to have a service
/// performed and progresses through a lifecycle described by its `status`
/// (draft, active, on-hold, revoked, completed, entered-in-error, or unknown)
/// and `intent` (proposal, plan, directive, order, and related values). It is
/// the FHIR workflow analogue of a paper or electronic order and is commonly
/// used to drive downstream workflows such as scheduling, specimen collection,
/// imaging acquisition, and result reporting, with the fulfilling actor
/// typically producing a DiagnosticReport, Procedure, or Observation that
/// references the originating request via `basedOn`.
///
/// # See also
///
/// - [`Patient`](crate::r5::resources::patient::Patient) — often the `subject` of the request.
/// - [`CodeableConcept`](crate::r5::types::CodeableConcept) — used for `category`, `body_site`, and other coded fields.
/// - `DiagnosticReport`, `Procedure`, and `Observation` — typical resources that fulfill a ServiceRequest.
///
/// # Examples
///
/// ```
/// use fhir::r5::resources::service_request::ServiceRequest;
///
/// let value = ServiceRequest::default();
/// let json = ::serde_json::to_value(&value).unwrap();
/// let back: ServiceRequest = ::serde_json::from_value(json).unwrap();
/// assert_eq!(value, back);
