Change the capacity of this vector to the specified newCapacity. If an exception is thrown (other than by the move constructor of a non‐copy‐insertable value_type), *this is unaffected. Throw bsl::length_error if newCapacity > max_size(). This method requires that the (template parameter) type VALUE_TYPE be move‐insertable into this vector (see {Requirements on VALUE_TYPE}). Note that the capacity of this vector after this operation has completed may be greater than newCapacity.
