Official
Rust's appeal stems from its unique balance of reliability, efficiency, tooling, and extensibility, which empowers users to tackle new domains, and future development must preserve this balance through clearer goals, expanded extensibility, and better ecosystem guidance.
Propose new 2026 Rust Project goals using a simplified template and structured team support requests, with submissions open until January 2026.
Rust Foundation Project Directors update on the Maintainers Fund, crates.io security and sustainability initiatives, Rust-C++ interop progress, draft 2026-2028 strategic goals, and RustConf 2026 preparations.
The Rust Project shifts to annual goals, Rust in Linux is no longer experimental, CPython explores Rust integration, and the Foundation secures $650k for 2026 priorities.
Rustup 1.29.0 beta introduces concurrent downloads/updates for performance, broader platform support, and `PATH`-aware rust-analyzer, calling for testers.
Newsletters
The Embedded Rustacean Issue #61 www.theembeddedrustacean.com
The latest Embedded Rustacean newsletter offers a curated roundup of news, resources, events, and job opportunities in the embedded Rust ecosystem.
Scientific Computing in Rust's latest covers a major multi-physics update for `DeepCausality`, the new `rlst` linear algebra toolbox, and new crates for interpolation and Fast Multipole Methods.
Project/Tooling Updates
Identifies a data race between a non-atomic read and write across two threads, leading to Undefined Behavior.
`cargo-coupling` is a Rust tool that visualizes and analyzes project coupling across three dimensions—strength, distance, and volatility—to help achieve balanced design and improve maintainability.
Announcing Asterinas 0.17.0 asterinas.github.io
Asterinas 0.17.0 significantly advances this Rust OS kernel with a new NixOS distribution, improved RISC-V support, core kernel features, and the `sctrace` syscall compatibility tool.
Tuitar is a new terminal-based guitar training tool designed to run standalone on ESP32 hardware, potentially utilizing embedded Rust.
Gitoxide's latest updates include transitioning to pure Rust `zlib-rs`, extensive use of Gen-AI for parsing and refactoring, and progress on SHA256 support and `gix-blame`'s diff-slider.
Mullvad VPN introduces GotaTun, a Rust-based WireGuard implementation for its app, significantly reducing crashes and improving performance by replacing the problematic `wireguard-go` and streamlining FFI with their existing Rust codebase.
Wgpu v28.0.0 introduces full Mesh Shader support, renames push constants to `immediates` with a spec-aligned API, makes `enumerate_adapters` async, and improves multiview rendering capabilities.
`rustc_codegen_gcc` details recent progress on upstream GCC patch integration and internal development, enabling broader architecture support like initial `m68k` cross-compilation.
Observations/Thoughts
This article proposes a complete syntactic and semantic design for Rust's fallibility effect, advocating for `throws` to annotate fallible functions/blocks/closures, `throw` for error creation, and abstract `impl Try` for ergonomic, allocation-free heterogeneous errors.
Leverage Rust's expression blocks to encapsulate intermediate logic, reduce scope pollution, and manage mutability for cleaner, more robust code.
Netstack.FM is a Rust networking and systems programming podcast, featuring deep dives and interviews with creators of projects like Tokio, Hyper, Rustls, and Cloudflare's Pingora.
Rust Walkthroughs
Learn to unit test your Axum HTTP handlers in Rust by simulating requests in-memory using `tower::ServiceExt` without relying on a live network.
Part 2 of building an LLM in Rust, this article details implementing a CPU-bound tensor library from scratch, covering optimized matrix multiplication (Rayon, cache-blocking, SIMD), numerically stable softmax, broadcasting, and other core operations.
