enumerate_view ( ) requires std:: default_initializable < V > = default ;	(1)	(自 C++23 起)
constexpr explicit enumerate_view ( V base ) ;	(2)	(自 C++23 起)

构造一个 enumerate_view 。

1) 默认构造函数。值初始化底层视图


         
          base_

。构造完成后，


         base()

返回 V ( ) 的副本。

2) 使用 std :: move ( base ) 初始化底层视图


         
          base_

。

参数

base

底层视图
