Package dev.hardwood.row

package dev.hardwood.row

Value types for nested Parquet structures accessed through RowReader.

PqStruct provides typed access to struct fields. PqList, PqIntList, PqLongList, and PqDoubleList represent list columns with primitive specializations to avoid boxing. PqMap represents map columns.
