Summary: A clean `cargo build` raises four warnings: - `hash_set_impl` only contains trait impls, so the `pub use hash_set_impl::*;` re-export brings in no names and triggers `unused_imports`. The `mod` declaration is kept so the impls stay in the crate. - `PatriciaTree::iter` and the two `ReverseGraph::rev` signatures elide a lifetime on `&self` while hiding it in the return type, which triggers `mismatched_lifetime_syntaxes`. Spell the hidden lifetime as `'_`. No behavior change; `cargo build --all-targets` is now warning free and all tests pass. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
