rust: run a clippy pass with the latest stable version Our current version of clippy is older than the latest stable. The newest version has new lints that are moslty good advice, so let's apply them ahead of time. This has the added benefit of reducing the noise for developpers like myself that use clippy as an IDE helper, as well as being more prepared for a future clippy upgrade.
