Introduction to a Rust Client for Enhanced FHIR Package Management
tlq-fhir-registry-client — Rust dev tool // Lib.rs
Summary
tlq-fhir-registry-client is a Rust development tool designed for loading and caching FHIR packages. This client provides functionality to search and download packages from the Simplifier registry, in addition to using local cache, handling version resolution and dependency management.
Details
This crate aims to enhance flexibility and extensibility in handling FHIR packages. The core component is `RegistryClient`, which adopts a trait-based approach for package caching. This allows for implementing diverse backends—such as file systems (default), databases, Redis, or S3—meaning developers can select the optimal cache strategy for their environment. Specifically, it supports not only loading from local caches but also remote searching and downloading via integration with the Simplifier registry. Furthermore, its technical strength lies in standardizing basic package operations (existence check, retrieval, storage, listing) based on the `PackageCache` trait definition. This design is valuable for achieving reliable dependency resolution and data access in environments where FHIR version management is complex.
