std::experi...es::Sentinel(3) C++ Standard Libarystd::experi...es::Sentinel(3) NAME std::experimental::ranges::Sentinel - std::experimental::ranges::Sen- tinel Synopsis Defined in header <experimental/ranges/iterator> template < class S, class I > concept bool Sentinel = (ranges TS) Semiregular<S> && Iterator<I> && WeaklyEqualityComparableWith<S, I>; The Sentinel concept specifies the relationship between an Iterator type and a Semiregular type whose values denote a range. Let s and i be values of type S and I, respectively, such that [i, s) denotes a range. Sentinel<S, I> is satisfied only if: * i == s is well-defined. * If bool(i != s) then i is dereferenceable and [++i, s) denotes a range. The domain of == can change over time. Given an iterator i and sen- tinel s such that [i, s) denotes a range and i != s, [i, s) is not required to con- tinue to denote a range after incrementing any iterator equal to i (and so i == s is no longer required to be well-defined after such an increment). http://cppreference.com 2022.07.31 std::experi...es::Sentinel(3)
