decltype(auto)	operator* () const
	Dereference operator, which returns the current value. More...

auto	operator-> () const
	Arrow operator, return a pointer (possibly a fancy pointer) to the current element. More...

Self_t &	operator++ ()
	Pre-increment operator, which advances the position one step and returns a reference to the iterator itself. More...

auto	operator++ (int)
	Post-increment operator, which advances the position one step. More...

Self_t &	operator-- ()
	Pre-decrement iterator, which moves one step back and returns a reference to the iterator itself. More...

auto	operator-- (int)
	Post-decrement operator, which moves one step back and returns a copy of the iterator before the decrement. More...

Self_t &	operator+= (std::ptrdiff_t delta)
	Addition assignment operator, which moves the iterator forward by the given number of steps, and returns a reference to the iterator itself. More...

Self_t &	operator-= (std::ptrdiff_t delta)
	Subtraction assignment operator, which moves the iterator backward by the given number of steps, and returns a reference to the iterator itself. More...

Self_t	operator+ (std::ptrdiff_t delta) const
	Addition operator, which returns a new iterator that is the given number of steps ahead of the current iterator. More...

Self_t	operator- (std::ptrdiff_t delta) const
	Subtraction-of-integer operator, which returns a new iterator that is the given number of steps behind of the current iterator. More...
