[ty] Use `smallvec_inline!` more consistently by AlexWaygood · Pull Request #22720 · astral-sh/ruff

AlexWaygood · 2026-01-19T13:20:48Z

Summary

This is another refactor pulled out of #22718 that should have 0 behaviour changes. We were being a bit inconsistent on main about whether we were using smallvec![] or the newer smallvec_inline![] feature. This PR switches us over to using smallvec_inline![] wherever it's possible to do so.
