Crate yuzu_data 

yuzu-data — native I/O layer. Reads per-symbol gzip CSV price files into yuzu-core Panel matrices. NOT a dependency of yuzu-core (which stays WASM-pure); yuzu-data depends on yuzu-core, never the reverse.

Modules

combined

Combined per-field panel files: one wide gzip CSV per series (panels/{name}.csv.gz, header day,SYM1,SYM2,…, one row per trading day, empty cell = NaN), holding the full universe. The container reads ONE object per series instead of hundreds of per-symbol files. Same gzip-CSV conventions as csv_io/fundamentals.

csv_io

Per-symbol gzip CSV I/O. Files hold full adjusted OHLCV (day,adj_open,adj_high,adj_low,adj_close,volume, oldest-first); parse_series extracts one chosen Field column into (day, value) rows.

error

fundamentals

Per-symbol gzip CSV I/O for fundamentals — the native mirror of the Worker’s factor-panels.ts export. Files hold dense, forward-filled fundamental fields (day,pe,ps,pb,…, oldest-first); parse_fundamentals extracts one field column into (day, value) rows. Same format/conventions as csv_io.rs.

industry

Build the symbol -> sector map the yuzu-core neutralization ops need, from the tracked/*.csv.gz snapshot (symbol,sector,market_cap).
