pub fn encode_bars(data: &[Bar]) -> Result<RecordBatch, ArrowError>Expand description
Encodes bars as a display-friendly Arrow [RecordBatch].
Emits Float64 columns for OHLCV values, Utf8 columns for the
instrument ID and bar type, and Timestamp(Nanosecond) columns for
event and init times. Mixed-instrument batches are supported. Precision
is lost on the conversion to f64; use
crate::arrow::bars_to_arrow_record_batch_bytes for catalog storage.
Returns an empty [RecordBatch] with the correct schema when data is empty.
ยงErrors
Returns an [ArrowError] if the Arrow RecordBatch cannot be constructed.
