Move the elements of type `allocator_traits<ALLOCATOR>::value_type` in the specified range `[fromBegin .. fromEnd)]` into the uninitialized array beginning at the specified `toBegin` location, using the specified `allocator` to supply memory (if required), inserting at the specified `position` (after translating from `fromBegin` to `toBegin`) a newly created object constructed by forwarding `allocator` (if required) and the specified (variable number of) `arguments` to the corresponding constructor of the target type, ensuring that the specified `fromEndPtr` points to the first uninitialized element in `[fromBegin .. fromEnd)]` as the elements are moved from source to destination. 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 an exception is thrown during the in‐place construction of the new object, the input array is unaffected; otherwise, if a (copy or move) constructor throws an exception during this operation, the input elements in the range `[fromBegin .. *fromEndPtr)]` are left in a valid but unspecified state and the remaining portion of the input array is left in an uninitialized state. The behavior is undefined unless `fromBegin <= position <= fromEnd` and `toBegin` refers to space sufficient to hold `fromEnd ‐ fromBegin + 1` elements.
