- Someone 4y agoBut likely not at calculating that sum (which, nitpicking, isn’t “calculating the sum of 1M numbers”, but “calculating the sum of integers 1 through 1,000,000”), but at printing a constant. It’s possible the C library you used is faster at converting this particular integer to a string (performance will vary between different ones, and not necessarily with one being always faster than the other) and writing it than rust’s one, but also possible that the C compiler did the string conversion at compile-time, too, and compiled a call to puts (if you printed a newline at the end of your string)
