std::experimental::ranges::Range - cppreference.com (original) (raw)

Given an lvalue t of type std::remove_reference_t<T>, Range<T> is satisfied only if

• [ranges::begin(t), ranges::end(t)) denotes a range; and
• both ranges::begin(t) and ranges::end(t) are amortized constant time and non-modifying.
• If ranges::iterator_t<T> satisfies ForwardIterator, ranges::begin(t) is equality preserving.
