This concept refines input_iterator
by requiring that I
also model incrementable
(thereby making it suitable for multi-pass algorithms), and guaranteeing that two iterators to the same range can be compared against each other.
Unlike the LegacyForwardIterator
requirements, the forward_iterator
concept does not require dereference to return a reference.
