template< std::sized_sentinel_for<Iter> S > friend constexpr std::iter_difference_t<Iter> operator-( const move_iterator& i, const std::move_sentinel<S>& s ); |
(2) | (since C++20) |
Returns the distance between a move_iterator and a move_sentinel.
These function templates are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::move_iterator<Iter> is an associated class of the arguments.
Parameters
| i | - | std::move_iterator<Iter>
|
| s | - | std::move_sentinel<S>, where S models std::sized_sentinel_for<Iter>
|
Return value
1) s.base() - i.base()
2) i.base() - s.base()
