operator-(std::move_iterator<Iter>, std::move_sentinel)

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> 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()

operator-(std::move_iterator<Iter>, std::move_sentinel)

Parameters

Return value
