Does Rust handle anything with memory barriers? I can handle concurrency, interrupt handlers, etc, but memory barriers always trouble me.

  It will force your code to be memory safe, but it can't enforce that you have the correct semantics. https://doc.rust-lang.org/std/sync/atomic/fn.fence.html https://doc.rust-lang.org/std/sync/atomic/fn.fence.html exists, but Rust can't force you to say, use the correct ordering.

    Right, so no different than C in this regard.

      Really, you should rarely be using raw memory barriers even in C, IMO. The C11/C++11 atomics model (which Rust also uses) is substantially nicer. Though, unfortunately, still extremely tricky to get right.

        The only time that I ever had to worry about that was when writing drivers for the Linux kernel.
