| <p>在兼容模式下，只要两个注解都归一为相同的 Fory <code>array<T></code> Schema，写入端和读取端就可以为同名字段使用不同的 Python 载体。例如，声明为 <code>pyfory.Array[pyfory.Int32]</code> 的写入端字段，可以由匹配字段声明为 <code>pyfory.NDArray[pyfory.Int32]</code> 的 Python 类读取，读取端会得到 NumPy <code>int32</code> ndarray。反向模式同样适用于 <code>pyfory.PyArray[T]</code>；该名称始终表示 Python <code>array.array</code>。</p> |
| <p>PyArrow 是独立的行式/列式格式能力，不是 <code>pyfory.PyArray</code> 载体。使用 <code>pyfory.format.from_arrow_schema(...)</code> 和 <code>pyfory.format.to_arrow_schema(...)</code> 在 PyArrow Schema 与 Fory Row Format Schema 之间转换。</p> |
