Rust is tier-1 language at Microsoft

Original Article

Hacker News Discussion

📝 Discussion Summary (Click to expand)

1. Rust’s Tier‑1 status at Microsoft

“Specifically, it joins a list of existing Tier 1 languages (C++, C#, and TypeScript), as 'one of the best‑supported languages for internal development at Microsoft'.” – swiftcoder

2. Debugging and tooling support for Rust in Visual Studio / VS Code

“So when will we get tier 1 debugging support in Visual Studio?” – ComputerGuru
“I've used VS for debugging and profiling Rust binaries… wrote a tool to auto‑generate a wrapper .sln …” – MaulingMonkey

3. Trade‑offs and suitability of Rust for different application domains

“I work in gamedev. Here is a simple answer: proprietary gaming platforms have no plans to support Rust.” – SleepyMyroslav
“Rust is great for rapid prototyping, IMO… Rust has a saying 'if it compiles, it works'.” – bryanlarsen

4. Memory‑safety and corporate motivations driving Rust adoption

“Rust's memory safety design will help Microsoft improve a gigantic portfolio of products that have been known to have lots of CVEs and 70% of them are memory‑safety issues…” – devy

🚀 Project Ideas

RustDebugger Enhancer for Visual Studio

Summary

  • Provides rich debugger visualizers (natvis) for Rust standard collections, enums, and common types inside Visual Studio, solving the poor debugging experience reported by Rust developers who miss the clarity of C#/C++ debugging.
  • Core value: Enables productive, tier‑1‑level debugging of Rust code in VS without leaving the IDE, matching the debugging comfort of Microsoft’s other primary languages.

Details

Key Value
Target Audience Rust developers using Visual Studio on Windows
Core Feature Natvis visualizer package + VS extension that integrates with rust-analyzer to show pretty‑printed values while debugging
Tech Stack C# (.NET) for VS extension, natvis XML, optional Rust procedural macro to embed visualizer metadata
Difficulty Medium
Monetization Hobby

Notes

  • HN commenters complained about “poor debugger visualizers for standard containers and enums” (MaulingMonkey) and wished for tier 1 debugging support in VS (ComputerGuru). This extension directly addresses those pain points.
  • Could spark discussion on improving the VS‑Rust debugging experience and potentially become a baseline offering from Microsoft’s Rust tooling team.

Lightweight Rust/Tauri Desktop App Framework

Summary

  • Starter kit/template for building native Windows desktop apps with Rust + Tauri (instead of Electron/WebView2) that targets <100 MB RAM usage, answering the bloat complaints about apps like the Windows Weather app.
  • Core value: Delivers Microsoft‑grade desktop experiences with the safety and performance of Rust while keeping memory footprint low, directly addressing the “1 GB RAM” frustration expressed by hn_submit and others.

Details

Key Value
Target Audience Windows desktop app developers seeking low‑memory footprint (internal tools, utilities, consumer apps)
Core Feature Template/project generator for Tauri + Rust with pre‑configured WinUI3 optional UI, plus guidance for minimizing WebView2 usage and optimizing binary size
Tech Stack Rust, Tauri, optionally windows-rs for WinUI3, HTML/CSS/JS UI (React/Svelte/Vue)
Difficulty Medium
Monetization Hobby

Notes

  • hn_submit lamented “Visual Studio 2022 instance uses 2 Gigabytes (!!) of RAM” and compared it unfavorably to lightweight alternatives; this template offers a path to sub‑100 MB apps.
  • Commenters discussed using Tauri and windows-rs for native UI (larodi, tcfhgj); this idea bundles those components into an easy‑to‑start solution.

MSVC-Compatible High-Speed Linker Wrapper

Summary

  • Drop‑in tool that invokes mold or lld‑link in place of link.exe for MSVC builds, giving linker speeds hundreds of times faster while preserving MSVC‑style incremental linking where possible.
  • Core value: Cuts build‑link latency dramatically, satisfying the desire for modern linkers like mold/wild expressed by HN commenters (jcelerier, delta_p_delta_x).

Details

Key Value
Target Audience Windows C++/Rust build engineers using MSVC
Core Feature Wrapper script/executable that detects MSVC invocations and forwards to mold/lld-link with appropriate args, preserving incremental linking behavior
Tech Stack Rust (or C++) wrapper, parsing MSVC command line, invoking mold/lld-link via std::process
Difficulty Medium
Monetization Hobby

Notes

  • delta_p_delta_x noted “mold or wild's full link is a few hundred times faster than a link.exe incremental relink” and wished for better linker support.
  • jcelerier highlighted the speed advantage of mold over link.exe; this wrapper would let MSVC users reap those benefits without leaving their existing build pipelines.

Rust‑C++ Interop Codegen Service

Summary

  • CLI/SaaS that parses a C++ header/library and generates idiomatic Rust bindings (using cxx/bindgen) plus safety wrappers, reducing manual interop effort for large codebases.
  • Core value: Enables gradual, safe adoption of Rust in existing C++ projects, directly addressing the interop friction highlighted by commenters (abbefaria27, kibwen).

Details

Key Value
Target Audience Teams maintaining large C++ codebases looking to adopt Rust incrementally
Core Feature Automated binding generator that outputs safe Rust crates with cxx bridges, handling complex types, callbacks, and generating documentation
Tech Stack Rust (bindgen, cxx), Clang AST parser, optional web UI for configuration
Difficulty High
Monetization Revenue-ready: {SaaS subscription per seat or per LOC}

Notes

  • abbefaria27 asked “What’s the story for Rust‑C++ interoperability these days? That’s what kills adoption.” kibwen suggested focusing on the 1 % of code with greatest attack surface.
  • This service would automate the generation of safe bindings, turning a major pain point into a streamlined workflow and could be a natural topic for HN discussion on interop best practices.

Incremental Rust Build Accelerator

Summary

  • Cargo plugin that integrates remote caching (sccache/distcc) and fine‑grained incremental compilation to cut Rust compile times, especially for macro‑heavy crates.
  • Core value: Makes large Rust projects feel as responsive as incremental C# builds, tackling the long compile‑time pain point mentioned by multiple commenters (eduke, The primary downside of Rust is the long compile times).

Details

Key Value
Target Audience Rust developers working on large projects (especially with macros like serde) who suffer long compile times
Core Feature Plugin that caches compilation artifacts locally and remotely, using sccache/distcc, and increments only changed parts
Tech Stack Rust, sccache (or custom gRPC‑based cache), Cargo plugin interface
Difficulty Medium
Monetization Hobby

Notes

  • edukite observed “First compile. Every another will be significantly faster since compiler is incremental” but noted macro‑heavy crates still cause long builds.
  • Commenters discussed the desire for faster compile times and the potential of distributed caching; this plugin offers a practical, drop‑in solution that could see wide adoption in the Rust community.
