  1. The build patterns are awkward because of the borrow checker, the complexity is obvious from articles like this. So my conclusion is actually that optional named parameters are very much needed in Rust to alleviate the creation of objects with a less heavy solution that is more efficient, easier to read and that doesn’t require the creation of intermediate objects.

    Another alternative is to make functions and methods optionally pass ownership, only if the function/method output is assigned to a variable.

  2. I disagree. First, often you can get away with having one or two methods or a plain struct to work with. The builder just ensures a nice and flexible interface while keeping open the door to later changes. Also the complexity cost is mostly paid by libraries which are usually meant to be reused, thus amortizing the investment.
