  • Rust: Box Is a Unique Type
    7 projects | news.ycombinator.com | 2 May 2024
    If you have an object that's !Unpin, then Miri will not apply uniqueness rules to anything containing it [0], including boxes and &mut references. (In the example code, replacing the PhantomPinned with a () will make Miri complain again.) This is considered a temporary (if long-lived) measure to allow async executors to manipulate pinned futures without invalidating all their references and whatnot. Thus, it might be seen as undetected UB, in lieu of a permanent solution.

    That would be true if you used `Vec::clear` too, it doesn't allocate a new vector. My point was that you still end up running Drop implementations with RepeatedField, just not all at once. See https://play.rust-lang.org/?version=stable&mode=debug&editio...

    That's a valid Unix path, but rust's quoting does nothing to stop it: https://play.rust-lang.org/?version=stable&mode=debug&editio...
  • Borrow Checking Without Lifetimes

    Self-referential structs work fine in Rust and always have.

    https://play.rust-lang.org/?version=stable&mode=debug&editio...

    The compiler will correctly prevent you from moving the value.

    The other way to have a struct that starts out as non-self-referential and then becomes self-referential can be achieved with `unsafe` and `Pin::new_unchecked`, which is how `async {}` is handled.

    In rust as currently stands: https://play.rust-lang.org/?version=stable&mode=debug&editio...

    On the other hand, both this wrapper and yours are counterproductive if the element size is dynamic (e.g. perhaps you're dealing with some nonsense like:)

  • New Linux glibc flaw lets attackers get root on major distros

    Overflow checks turn into two's compliments' wrapping, but that's only considered acceptable because bounds checks are not turned off.

  • Atomics and Concurrency

    I have no idea what you're talking about, but it sounds unnecessarily complicated and why I don't use Rust for any serious work.

    This demonstrates the ABA problem in safe Rust: https://play.rust-lang.org/?version=stable&mode=debug&editio...

    Substitute the sleep with a combination of doing computation/work and the OS thread scheduler, and you can see how the bug surfaces.

    Unfortunately the go playground doesn't seem to support emitting assembly?
