fhir 1.2.0

Fast Healthcare Interoperability Resources (FHIR) data model for Rust: the complete FHIR R5, R4, and R3 resources, datatypes, and code systems as serde-serializable types, plus a spec-driven code generator.
//! Population
//!
//! URL: http://hl7.org/fhir/StructureDefinition/Population
//!
//! Version: 4.0.1
//!
//! A definition of a set of people that apply to some clinically related
//! context, for example people contraindicated for a certain medication
//!
//! FHIR R4: <https://hl7.org/fhir/R4/>

// The `types` import is unused by a handful of types that have only primitive fields.
