Function laminar_batch_export_column 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn laminar_batch_export_column(
    batch: *mut LaminarRecordBatch,
    column_index: usize,
    out_array: *mut FFI_ArrowArray,
    out_schema: *mut FFI_ArrowSchema,
) -> i32

Export a single column from a RecordBatch to the Arrow C Data Interface.

Safety

batch, out_array, and out_schema must be valid non-null pointers; column_index must be in range; caller must call the release callbacks.
