When returning an immutable reference to a private struct field. (On mobile and used vertical bars instead of a bunch of HTML codes)

    In the context of vectors I prefer my APIs to return an empty set rather than an None-option. This makes handling it much easier because you can still iterate over it, it just has nothing.

    I can see that argument. But you can also iterate over an Option-wrapped response with something like for x in xs.into_iter().flatten() { ... }, and the Option gives you an extra bit of information that can be helpful in certain cases.
