RUST-ANALYZER SHIPS DIAGNOSTIC OVERHAUL AS COMPILER SETTLES GLOBAL_ASM ROLLBACK

By RepoJournal · Filed · About Rust

Rust-analyzer 0.3.2913 landed two new diagnostics for common pattern errors while the compiler team reverted an insta-stable global_asm feature that shipped without proper review.

Rust-analyzer's latest release [1] adds mutable-ref and array-pattern-without-fixed-length diagnostics, catching errors earlier in the IDE [1]. The team also tightened completion import exclusions to support sub-item filtering [2], letting developers exclude std::intrinsics::AtomicOrdering without blocking the whole module. Over on rust-lang/rust, the compiler team reverted the global_asm statement position feature [3] after discovering it shipped without FCP and contained implementation bugs that invalidated existing assumptions. Meanwhile, the compiler merged four focused PRs fixing impl_trait_redundant_captures lint suggestions that left stray `+` tokens [4], parsing mut restrictions [5], and hardening const parameter defaults [5]. The crates.io-index continues steady state with routine updates to qtcloud-devops-cli , greentic-telemetry , and new kglite submission .
