Module batch_eval 

Batch expression evaluation — operates on columns/DataChunks instead of per-row TypedValue evaluation. Falls back to None for unsupported patterns so callers can use the scalar evaluate() path.

Functions

evaluate_column

Try to evaluate an expression on a DataChunk, producing an output ValueVector. Returns None for unsupported patterns (caller falls back to scalar).

evaluate_filter_batch

Try to evaluate a predicate on a DataChunk in batch mode. Returns Some(Ok(SelectionVector)) if handled, None to fall back to scalar.
