Why didn't you use a Mutex?

  What are you thinking? I could have used a Mutex then cast the `&Mutex` to `&mut Mutex` so that I could call `.get_mut()`. But this didn't seem simpler.

    I wanted to avoid unsafe. Because unsafe introduces conceptual complications and it seemed to be simpler to avoid that in an example.
    • kevincox 3y ago
      Well you can't have a memory race without unsafe. The goal of the example was to show undefined behaviour.

        Ah, you wanted to show an example in Rust with unsafe where atomicity was not guaranteed.
