推导指引

哨位

take_view::sentinel::sentinel (C++20)

take_view::sentinel::base (C++20)

operator==(std::counted_iterator,take_view::sentinel) (C++20)

 

/*sentinel*/() = default;	(1)	(C++20 起)
constexpr explicit /*sentinel*/( ranges::sentinel_t<Base> end );	(2)	(C++20 起)
constexpr /*sentinel*/( /*sentinel*/<!Const> s )   requires Const &&            std::convertible_to<ranges::sentinel_t<V>, ranges::sentinel_t<Base>>;	(3)	(C++20 起)

构造哨位。

1) 默认构造函数。值初始化底层哨位。

2) 以 end 初始化底层哨位。

3) 从 /*sentinel*/<false> 转换到 /*sentinel*/<true> 。移动构造对应的成员。

参数

end	-	表示（可能有 const 限定的） V 的末尾的哨位
s	-	/*sentinel*/<false>
