helios-sof 0.1.47

This crate provides a complete implementation of the SQL-on-FHIR specification for Rust, enabling the transformation of FHIR resources into tabular data using declarative ViewDefinitions. It supports all major FHIR versions (R4, R4B, R5, R6) through a version-agnostic abstraction layer.
