//! Use FHIR R5 code systems as type-safe Rust enums.
//!
//! Run with:
//!
//! ```sh
//! cargo run --example code_systems
//! ```
//!
//! Every FHIR `CodeSystem` is generated into an enum under [`fhir::r5::codes`].
//! Each variant serializes to its canonical FHIR code string, so you get
//! compile-time checking and editor autocomplete instead of stringly-typed
//! codes, while the wire format stays exactly as FHIR specifies.
