I was just recently going through some old episodes from Software Engineering Radio when I came across this one episode featuring Casey Muratori, where he goes through some of his thoughts around his video from February 2023, titled "‘Clean’ Code, Horrible Performance". I was actually already aware of the video by this time, but listening through the episode gave me an itch to see these concepts in my reality, experiment them by myself.

    It would be interesting to see if an iterator instead of a manual for loop would increase the performance of the base case.

    My guess is not, because the compiler should know they are equivalent, but would be interesting to check anyway.

      Do you mean this for loop?

      for shape in &shapes {
  accum += shape.area();
}

      That does use an iterator

      for-in-loops, or to be more precise, iterator loops, are a simple syntactic sugar over a common practice within Rust, which is to loop over anything that implements IntoIterator until the iterator returned by .into_iter() returns None (or the loop body uses break).
