Move the elements of type `allocator_traits<ALLOCATOR>::value_type` in the range beginning at the specified `fromBegin` location and ending immediately before the specified `fromEnd` location into the uninitialized array beginning at the specified `toBegin` location, using the specified `allocator` to supply memory (if required). On return, the elements in the input range are invalid, i.e., their destructors must not be called after this operation returns. If a constructor throws an exception during this operation, the output array is left in an uninitialized state. If a constructor other than the move constructor of a non‐copy‐constructible type throws an exception during this operation, the input array is unaffected; otherwise, if the move constructor of a non‐copy‐constructible type throws an exception during this operation, the input array is left in a valid but unspecified state. The behavior is undefined unless `toBegin` refers to space sufficient to hold `fromEnd ‐ fromBegin` elements.
