constexpr move_iterator& operator++();
1
#
Effects: As if by ++current.
2
#
Returns: *this.
🔗
constexpr auto operator++(int);
3
#
Effects: If Iterator models forward_­iterator, equivalent to: 
move_iterator tmp = *this;
++current;
return tmp;
Otherwise, equivalent to ++current.
🔗
constexpr move_iterator& operator--();
4
#
Effects: As if by --current.
5
#
Returns: *this.
🔗
constexpr move_iterator operator--(int);
6
#
Effects: As if by: 
move_iterator tmp = *this;
--current;
return tmp;
🔗
constexpr move_iterator operator+(difference_type n) const;
7
#
Returns: move_­iterator(current + n).
🔗
constexpr move_iterator& operator+=(difference_type n);
8
#
Effects: As if by: current += n;
9
#
Returns: *this.
🔗
constexpr move_iterator operator-(difference_type n) const;
10
#
Returns: move_­iterator(current - n).
🔗
constexpr move_iterator& operator-=(difference_type n);
11
#
Effects: As if by: current -= n;
