23.3.14 Class template inplace_vector [inplace.vector]

23.3.14.4 Data [inplace.vector.data]

constexpr T* data() noexcept; constexpr const T* data() const noexcept;
Returns: A pointer such that [data(), data() + size()) is a valid range.
For a non-empty inplace_vector, data() == addressof(front()) is true.
Complexity: Constant time.
