reverse_iterator

namespace opentl {
    template <typename It>
    class reverse_iterator;
}

An iterator that reverses the direction of another iterator.

Template Parameters

Name	Description
`It`	The iterator type.

Type	Description
`iterator_type`	The iterator type.
`difference_type`	The difference type.

Name	Return Type	Description
`reverse_iterator()`		`reverse_iterator` constructor.
`reverse_iterator(iterator_type)`		`reverse_iterator` constructor.
`base()`	`iterator_type`	Returns the underlying iterator.
`operator*()`	`decltype(auto)`	Dereferences the underlying iterator and returns a reference to the value.
`operator++()`	`reverse_iterator&`	Increments the iterator and returns a reference to it.
`operator++(int)`	`reverse_iterator`	Increments the iterator and returns a copy of the previous iterator.
`operator--()`	`reverse_iterator&`	Decrements the iterator and returns a reference to it.
`operator--(int)`	`reverse_iterator`	Decrements the iterator and returns a copy of the previous iterator.
`operator+=(difference_type)`	`reverse_iterator&`	Advances the iterator by n and returns a reference to it.
`operator-=(difference_type)`	`reverse_iterator&`	Backtracks the iterator by n and returns a reference to it.
`operator[](difference_type)`	`decltype(auto)`	Dereferences the element n positions back and returns a reference to it.

Name	Return Type	Description
`operator+(it, n)`	`reverse_iterator`	Returns a copy of the iterator advanced by n.
`operator-(it, n)`	`reverse_iterator`	Returns a copy of the iterator backtracked by n.
`operator+(n, it)`	`reverse_iterator`	Returns a copy of the iterator advanced by n.
`operator-(lhs, rhs)`	`ptrdiff_t`	Returns the number of positions between two reverse iterators.
`operator==`	`bool`	Checks if two reverse iterators refer to the same position.
`operator<=>`	`auto`	Orders two reverse iterators by their reversed position.
