generator( const generator& ) = delete;	(1)	(C++23 起)
generator( generator&& other ) noexcept;	(2)	(C++23 起)

构造 generator。

1) 复制构造函数被删除。

2) 移动构造函数使用 std::exchange(other.coroutine_, {}) 构造底层的 coroutine_，以及用 std::exchange(other.active_, nullptr) 构造协程句柄的底层栈 (active_)。 注意，此前来自 other 迭代器不会失效，而是成为 *this 的迭代器。

参数

other

-

要被移入的协程对象。
