I'm not sure myself, does Fn correspond to reentrancy or is there some detail I am missing?

- armchairhacker 9mo ago`Fn`, `FnMut`, and `FnOnce` can also implement and not implement `Sync` (also `Send`, `Clone`, `Copy`, lifetime bounds, and I think `use<...>` applies to `impl Fn...` return types). EDIT: https://news.ycombinator.com/item?id=46750011 https://news.ycombinator.com/item?id=46750011 also mentioned `AsyncFn`, `AsyncFnMut`, and `AsyncFnOnce`.
