27.11.6 uninitialized_move [uninitialized.move]

template<class InputIterator, class NoThrowForwardIterator> NoThrowForwardIterator uninitialized_move(InputIterator first, InputIterator last, NoThrowForwardIterator result);
Preconditions: does not overlap with [first, last).
Effects: Equivalent to: for (; first != last; (void)++result, ++first) ::new (voidify(*result)) typename iterator_traits<NoThrowForwardIterator>::value_type(std::move(*first)); return result;
namespace ranges { template<input_iterator I, sentinel_for<I> S1, nothrow-forward-iterator O, nothrow-sentinel-for<O> S2> requires constructible_from<iter_value_t<O>, iter_rvalue_reference_t<I>> uninitialized_move_result<I, O> uninitialized_move(I ifirst, S1 ilast, O ofirst, S2 olast); template<input_range IR, nothrow-forward-range OR> requires constructible_from<range_value_t<OR>, range_rvalue_reference_t<IR>> uninitialized_move_result<borrowed_iterator_t<IR>, borrowed_iterator_t<OR>> uninitialized_move(IR&& in_range, OR&& out_range); }
Preconditions: [ofirst, olast) does not overlap with [ifirst, ilast).
Effects: Equivalent to: for (; ifirst != ilast && ofirst != olast; ++ofirst, (void)++ifirst) ::new (voidify(*ofirst)) remove_reference_t<iter_reference_t<O>>(ranges::iter_move(ifirst)); return {std::move(ifirst), ofirst};
[Note 1: 
If an exception is thrown, some objects in the range [ifirst, ilast) are left in a valid, but unspecified state.

template<class InputIterator, class Size, class NoThrowForwardIterator> pair<InputIterator, NoThrowForwardIterator> uninitialized_move_n(InputIterator first, Size n, NoThrowForwardIterator result);
Preconditions: does not overlap with .
Effects: Equivalent to: for (; n > 0; ++result, (void) ++first, --n) ::new (voidify(*result)) typename iterator_traits<NoThrowForwardIterator>::value_type(std::move(*first)); return {first, result};

Preconditions: [ofirst, olast) does not overlap with .
Effects: Equivalent to: auto t = uninitialized_move(counted_iterator(std::move(ifirst), n), default_sentinel, ofirst, olast); return {std::move(t.in).base(), t.out};

If an exception is thrown, some objects in the range are left in a valid but unspecified state.
