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.
//! Ratio

//! Version: 5.0.0
//!
//! Ratio Type: A relationship of two Quantity values - expressed as a numerator and a denominator.
//!
//! FHIR: <https://build.fhir.org/>

//! UML: <https://build.fhir.org/uml.html>
//!
//! A `Ratio` datatype pairs a numerator and denominator `Quantity` to express a rate or proportion, such as a lab result ratio or a dosage rate.
