Announcing Rust 1.96.0
Scored daily by a customisable AI persona to surface the most relevant engineering leadership news.
Rust release with new features; highly relevant to systems and infrastructure engineering.
Rust 1.96.0 stabilizes RFC 3550's new range types (e.g., core::range::Range) that implement IntoIterator and Copy, enabling storing slice accessors in Copy types without splitting start/end. It also adds assert_matches! and debug_assert_matches! macros (not in prelude to avoid collisions) and makes WebAssembly linking error on undefined symbols by default (removing --allow-undefined). Two security fixes address symlink extraction and URL normalization in third-party registries.
- Update to Rust 1.96.0, migrate public APIs to new range types, and update WASM build scripts to handle the new linker behavior.
For engineers building performance-critical infrastructure or WASM-based tooling, the new Copy ranges simplify zero-copy patterns, the linker change prevents silent bugs in WebAssembly modules, and the macros improve debugging in assertion-heavy code.
