Compare each element in the range beginning at the specified `start1` position and ending immediately before the specified `end1` position to the corresponding element in the range of the same length beginning at the specified `start2` position, as if using `operator==` element‐by‐element. Return `true` if every pair of corresponding elements compares equal, and `false` otherwise. Note that this implementation uses `operator==` to perform the comparisons, or bit‐wise comparison if the value type has the bit‐wise equality‐comparable trait.
