Circumventing dyn Safety

Well, we’re not really circumventing it, but rather working around it.

The basic idea is as follows:

  • You have a trait DoStuff that is not dyn safe.
  • You have a type is that fully parameterized, aka no type holes!
    • This means that to call the methods you’re interested in, you know their types in advance
    • This can also be relaxed, but makes it more complicated and left as an exercise to the reader :)

Example trait we’ll be looking at:
