std::experimental::ranges::InputIterator
Min standard notice:
Header: <experimental/ranges/iterator>
The InputIterator concept is a refinement of Iterator, adding the requirement that the referenced values can be read (via Readable) and the requirement that the iterator category tag be present.
# Declarations
template< class I >
concept bool InputIterator =
Iterator<I> && Readable<I> &&
requires { typename ranges::iterator_category_t<I>; } &&
DerivedFrom<ranges::iterator_category_t<I>, ranges::input_iterator_tag>;
(ranges TS)
# Notes
Unlike the input iterator requirements in the C++ standard, InputIterator in the Ranges TS does not require EqualityComparable.
