Module rs_data 

Data reading and Arrow [RecordBatch] conversion.

ReadStatData coordinates the FFI parsing of row values from a .sas7bdat file, accumulating them directly into typed Arrow builders via the handle_value callback, then finishing them into an Arrow RecordBatch for downstream writing. Supports streaming chunks with configurable row offsets and progress tracking.
