辅助类

common_type<std::basic_const_iterator> (C++23)

 

template< std::sized_sentinel_for<Iter> S > constexpr difference_type operator-( const S& s ) const;	(1)	(自 C++23 起)
template< /*not-a-const-iterator*/ S >     requires std::sized_sentinel_for<S, Iter> friend constexpr difference_type     operator-( const S& s, const basic_const_iterator& i );	(2)	(自 C++23 起)

返回 basic_const_iterator 及其哨兵之间的距离。

S 仅当它不是 basic_const_iterator 的特化时才满足仅供说明的概念 /*not-a-const-iterator*/。

参数

i, s

-

迭代器和哨兵，用于计算差值

返回值

1) base() - s

2) s - i.base()
