template < std::sized_sentinel_for <Iter> S >

friend constexpr std::iter_difference_t <Iter>

    operator- ( const std::move_sentinel <S> & s, const move_iterator& i ) ;
(1) (since C++20)
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>

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()
