//! Ratio

//! URL: http://hl7.org/fhir/StructureDefinition/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.
// Allow unused crate::r5::types as types;
