once_self_cell

9 226 7.3 Rust

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

Project mention: Ouroboros is also unsound | /r/rust | 2023-06-11

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.
