    @calcopiritus @hatchet That way you can pass a reference or anything that can be turned into a reference as an argument. So the caller can supply a &T, Box, Rc, Arc, … (I dont’t know if there is a blanket impl so that even T itself will work.

      Well, actually I would tend to agree that &[T] is preferable to AsRef in most cases; all of the smart pointers you mentioned can also easily be turned into plain references. I probably could have chosen a better example.
