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.

//! Parses the FHIR R5 "Data Elements" specification bundle, loaded from
//! `definitions/dataelements.json`, which is a FHIR `Bundle` resource whose entries hold the
//! `StructureDefinition`s for reusable data elements. The submodules here (`Bundle`, `Entry`,
//! `Resource`, `Element`, `Snapshot`, `Differential`, `Slicing`, `Discriminator`, and `Base`)
//! mirror the JSON shape of that bundle and its nested structure definitions, with each type
//! deriving `serde::Deserialize` so the raw specification file can be loaded directly into
//! Rust values. This parsed representation is the input that the crate's code generator walks
//! in order to emit the strongly typed FHIR data-element model used elsewhere in the crate,
//! making this module one stage in the overall specification-to-Rust generation pipeline.

// Namespace conveniences
