public record CsvChange(CsvChange.ChangeType type, int rowIndex, CsvRow oldRow, CsvRow newRow) extends Record
CSV Change - Represents a single change between two CSV documents CSV变更 - 表示两个CSV文档之间的单个变更

An immutable record capturing a row-level difference. Used by CSV diff operations to report additions, removals, and modifications.

一个不可变记录，捕获行级差异。被CSV差异操作用于报告添加、删除和修改。

CsvChange added = new CsvChange(ChangeType.ADDED, 3, null, newRow);
CsvChange removed = new CsvChange(ChangeType.REMOVED, 1, oldRow, null);
CsvChange modified = new CsvChange(ChangeType.MODIFIED, 2, oldRow, newRow);
