pub fn encode_instruments(
data: &[InstrumentAny],
) -> Result<RecordBatch, ArrowError>Expand description
Encodes instruments as a display-friendly Arrow [RecordBatch].
Emits a single schema built from the common [Instrument] trait surface.
Utf8 columns carry identifiers and enum names, Float64 columns carry
prices/quantities/fees, Timestamp(Nanosecond) columns carry activation,
expiration, and bookkeeping timestamps, and Boolean columns carry
is_inverse/is_quanto. Trait accessors that are not applicable to a
row (e.g. strike_price on a spot pair) emit as nulls, so mixed-type
batches round-trip cleanly. Variant-only metadata not reachable through
the trait is intentionally omitted; see the module-level comment.
Returns an empty [RecordBatch] with the correct schema when data is empty.
ยงErrors
Returns an [ArrowError] if the Arrow RecordBatch cannot be constructed.
