The Most Annoying Bug I've Had To Track Down

• rust

  2,682 92,831 10.0 Rust

  Empowering everyone to build reliable and efficient software.

  

The tricky part, which Rust does not do, is to ensure that this can always be done 100% of the time. This is basically the same problem as guaranteed RVO/NRVO or "(Named) Return Value Optimization" and "placement new" (see e.g. this old tracking issue). Because blocks support basically anything in their body, there are some cases where a temporary (or at least a move) is necessary. Further, carving out a precise specification of when the result can be created directly in place is both a) difficult and b) would be annoying for users to learn and pay attention to.

A case that was recently caught by miri (now that it can run on doctests) and fixed in std docs was where AtomicPtr::new(p: *mut T) -> AtomicPtr was used like AtomicPtr::new(&mut 10).
