This Week in Rust #669 is a curated roundup of community newsletters, project/tooling releases, blog posts, walkthroughs, research, the crate of the week, testing calls, and a detailed list of merged PRs across the Rust compiler, standard library, Cargo, rustfmt, Clippy, and rust‑analyzer, plus a brief compiler‑performance triage summary. No new RFCs were approved.

  • Community newsletters: Rust Trends, Embedded Rustacean.
  • Project updates: Slint 1.18 release.
  • Thought pieces on Arduino, FFI, LSP difficulty, Verus verification, Tokio performance.
  • Walkthroughs covering auto‑vectorization, inheritance patterns, static‑lib symbol collisions, async visual guide, Redis clone, ESP32 SWD programming, WASM time/panic traps, sqlx migration wrapper, checked arithmetic, ge…

Keeping up with the rapid pace of Rust’s ecosystem is essential for engineers who rely on its compiler, libraries, and tooling. The issue surfaces concrete PRs that affect stability, performance, and ergonomics (e.g., Vec::from_fn, DropGuard, and macro‑caching in rust‑analyzer), and highlights comm…

  5. Migrating the GitHub Copilot runtime to Rust, using Copilot

    The Copilot agent runtime was rewritten from a 130‑k‑line TypeScript/Node.js codebase into a native Rust library (~830 k lines of Rust) to reduce startup latency, memory use, and improve reliability. The migration was done incrementally (in‑place) across 128 PRs, with AI‑generated code handling most of the work. The new runtime exposes a C ABI for in‑process embedding by all six Copilot SDK langu…
