rxnorm-rrf

RxNorm Rich Release Format reading.

Locates the files of an unpacked RxNorm release (RXNCONSO.RRF, RXNREL.RRF, RXNSAT.RRF, and RXNSTY.RRF) and reads them streaming into typed rows by the documented column positions (the RxNorm technical documentation). The crate ships no RxNorm content; a deployment brings its own release under the UMLS licence.

Where it sits

rxnorm-rrf is one crate of FerroTERM, a pure-Rust FHIR terminology server for SNOMED CT, LOINC, and other clinical code systems. The crates are published so other projects can reuse them; the API is pre-1.0 and moves with the FerroTERM release train. Documentation: https://docs.rs/rxnorm-rrf.
