I lack Rust experience to comment on your suggestion but it does make me wonder if the author has provided a means for feedback in order to make this "More Effective Rust" (No pun intended if you're familiar with Meyers' followup book.)
- weavie 3y agoThe other commenters to this are correct, `Vec::new()` doesn't actually allocate so the code in the book is fine. I had a brain fart. If that function was taking a reference to an object that was fairly expensive to create a default value for then my conundrum would still exist.
