          Are you copying a Result or Option?

            I don’t understand…? I think I never explicitly run a method/function that is called copy (there isn’t at least not for the trait Copy)

              Lol yea I think the .copy() comment was a little gaslighting or something.

    I thought it was randomly adding Send and Sync traits to function signatures until rustc is happy.

    This was me in courses that used C. Keep adding and removing * and & until the IDE was happy and it usually worked.

      New your program deadlocks instead of crashing, peak safety.

    Follow up of: “Mmm… should I put lifecycle annotation in these 10 structs or just use and Rc and call it a day?”. Rc and Box FTW.

    I think that’s the only thing I dislike about rust. Not having to use * to dereference but later having to use is tad confusing. I know it’s still clever solution but in this case I prefer c++'s straightforward consistency.

    Using ampersand never was problematic for me.

      C++ does have the problem that references are not objects, which introduces many subtle issues. For example, you cannot use a type like std::vector<int&>, so that templated code will often have to invoke std::remove_reference<T> and so on. Rust opts for a more consistent data model, but then introduces auto-deref (and the Deref trait) to get about the same usability C++ has with references and operator->. Note that C++ will implicitly chain operator-> calls until a plain pointer is reached, whereas Rust will stop dereferencing once a type with a matching method/field is found. Having deep knowledge of both languages, I’m not convinced that C++ features “straightforward consistency” here…

    Same for C, & yields a pointer to a value, and * allows you to access the data. (For rust people, a pointer is like a reference with looser type checking)

      We have pointers in Rust, too :) see documentation

        I doubt many people have ever use that or any of the other low level memory API. The main appeal of rust is not having to do that.

          Sure, but raw pointers and unsafe Rust are still covered in the official learning material, so I assume that most Rust devs know about raw pointers.

        honestly with Go in general I’m in a perpetual cycle of being annoyed with it and then immediately being amazed when I find some little trick for efficiency - with stringer interfaces and the like
