Ouroboros is also unsound

• ouroboros

  2 467 7.7 Rust

  Easy self-referential struct generation for Rust. (by someguynamedjosh)

• once_self_cell

  9 226 7.3 Rust

  Safe-to-use proc-macro-free self-referential structs in stable Rust.

This issue says "Migrate code to use self_cell instead." That page says "It has undergone community code review from experienced Rust users." Looking at the review, issues were found and fixed earlier on, but my interpretation of the end of the thread is more that folks stopped responding with concerns, so confidence is now assumed but still not proven. The same was true of most (all?) other crates trying to solve the same problem, until enough people did find the unsoundness holes unique to each crate.

• miri

  120 3,955 10.0 Rust

  An interpreter for Rust's mid-level intermediate representation

  

You can run miri and it will tell you if the given run triggered any undefined behavior. It will not analyze it for every possible use of the code, but checking for the presence of this specific issue using it should be fairly simple.
