RUST-ANALYZER CLOSES PATTERN TYPE GAP WHILE COMPILER FIXES CI INFRASTRUCTURE

Rust-analyzer shipped full pattern type support and fixed a critical issue with NonZero types, while the compiler pipeline recovered from a broken Solaris repo that took down CI.

The analyzer landed comprehensive pattern type handling [1] alongside a follow-up fix for TyKind::Pat edge cases hit on stable through NonZero types [2], closing a gap that was silently breaking hover diagnostics. On the compiler side, the Solaris build infrastructure is back online after the dilos apt repo went dead [3], which was blocking the entire CI pipeline with 403 errors. Rustfmt also gained the ability to properly format match expressions with or-patterns containing comments [4], fixing a regression where entire match blocks were being skipped. The analyzer now shows unsafe modifiers in signature help [5], and added a diagnostic for E0614 field access errors . Crates.io continues routine dependency maintenance with Svelte 5.55.7 [6], SvelteKit 2.60.1 [7], and pnpm 11.1.2 [8] bumps, none of which require action.

Action items

→ If you're seeing hover failures on NonZero types, update rust-analyzer to pick up pattern type fixes rust-lang/rust-analyzer [plan]
→ Monitor CI status - dilos repo is restored but verify Solaris builds complete successfully rust-lang/rust [monitor]
→ Run rustfmt across your codebase to fix previously-skipped match formatting rust-lang/rust [plan]
