--all-targets
is now passed to clippy on CI. Temporarily,-- -A renamed_and_removed_lints
is passed as well. This can beremoved once the clippy::* attribute syntax is available in stable.
Additionally, clippy-preview is now installed and run on stable.
We were previously running clippy on an old nightly from late June and
no new warnings (except the one noted above) are raised on nightly so
switching to the -preview component on stable shouldn't introduce
churn. Also, unlike with rustfmt, we can fix and merge any clippy
recommendations before they hit the stable channel, so we don't have to
sync with new releases.
