Rust 1.94: Faster Slice Iteration with array_windows() and Cleaner Cargo Configuration
Rust 1.94 brings two practical improvements: array_windows for safe, faster slice iteration, and Cargo’s include key that lets teams centralise shared configuration files across projects. Adopting it is as simple as swapping .windows(4) for .array_windows() where you currently destructure windowed slices, or adding an optional include entry to your ~/.cargo/config.toml if you want a tidy way to share dev‑only settings. The new TOML 1.1 parser lets manifests use modern syntax—multiline inline tables, trailing commas, and \xHH escapes—while Cargo automatically rewrites older manifests on publish so that crates keep their MSRV low for downstream users. With array_windows now stable in const contexts and a host of other helpers (LazyCell, LazyLock, SIMD intrinsics, Euler’s constant) stabilized, the compiler feels a bit more powerful without breaking existing code.
Rust 1.94: Faster Slice Iteration with array_windows() and Cleaner Cargo Configuration
Rust 1.94 introduces significant improvements, including the new `array_windows()` function for faster and safer slice iteration, and an `include` key in Cargo that allows teams to centralize shared configuration files across projects. The update simplifies coding by replacing the `.windows(4)` pattern with `.array_windows()`, eliminating unnecessary bounds checks and improving performance. Additionally, Cargo now supports the TOML 1.1 parser, enabling modern syntax features while ensuring compatibility with older manifests through automatic rewriting during publication. Other stabilized APIs and helpers enhance the compiler's capabilities without disrupting existing code, making Rust 1.94 a powerful update for developers
