zip_transform_view() = default;	(1)	(C++23 起)
constexpr zip_transform_view( F fun, Views... views );	(2)	(C++23 起)

1) 默认构造函数。值初始化存储的可调用对象与所有适配的 view 对象。

若

• F 不满足 default_initializable ，或
• std::is_default_constructible_v 对 Views... 中至少一个类型为 false ，

则默认构造函数被删除。

2) 从 fun 移动构造存储的可调用对象，并从 views... 中对应的视图移动构造每个适配的 view 对象。

参数

f	-	用于生成 zip_transform_view 的元素的可调用对象
views	-	要适配的视图对象
