This lint checks the return values of all `pub` functions, methods, and trait methods within a crate, emitting a warning if any proscribed types are returned. Configurable via `disallowed-pub-return-types` in `clippy.toml`. This is intended to prevent internal error types (e.g., `anyhow::Result`) from leaking into public APIs. changelog: [`disallowed_pub_return_types`]: New lint
