read --wire →
Rust
The compiler team shipped five rollups tackling real-world regressions and dead code, while crates.io upgraded serde to syn 3 and converted its mock handlers to TypeScript for type safety.
read --wire →
Rust
Rustc just pulled in a critical crossbeam-epoch security update while rust-analyzer ships a major release with higher-ranked trait bound lowering and memory optimizations.
read --wire →
Rust
The standard library gained const-time binary search and Miri fixed a critical Android I/O gap that broke vectored file operations in testing.
read --wire →
Rust
Miri's readiness watcher table got replaced with per-FD state tracking, catching undefined behavior that futures-rs shipped with and forcing an emergency fix.
read --wire →
Rust
Miri ripped out the unreliable FileDescription::destroy pattern and fixed critical race conditions around file descriptor closure, while the compiler landed strict new lints against POSIX symbol hijacking that have been catching real production bugs.
read --wire →
Rust
Rust-analyzer's extract variable refactor now preserves whitespace from macro input, fixing a bug that corrupted generated code with invalid syntax like `&mutbar`.
read --wire →
Rust
An unsound analysis in coroutine MIR saved local remapping just shipped, plugging a hole discovered while working on async-drop code.
