A key enabler is a new internal code generation back end called rustc_codegen_utc, which connects the Rust compiler to Microsoft's existing Visual C++ (MSVC) back end, the Universal Tuple Compiler (C2.DLL). This lets Rust code compile through the same mature, well-tested pipeline used for C and C++, enabling low-level Windows development such as drivers and kernel components without duplicating compiler infrastructure. The tool is currently internal-only, used by over a hundred Microsoft Rust projects, but Microsoft has signaled plans to upstream test and back-end infrastructure work into the public Rust project, suggesting eventual external release via Visual Studio or VS Code updates. In the meantime, external developers can use rust-analyzer with MSVC C++ Build Tools and a Microsoft-developed Windows crate for direct Windows API access. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is rustc_codegen_utc and how does it let Rust use the Visual C++ compiler back end? rustc_codegen_utc is Microsoft's internal Rust code generator that connects the Rust compiler to the existing MSVC back end, called the Universal Tuple Compiler (implemented as C2.DLL). It takes rustc's bytecode output, generates native code, and emits .OBJ files for the MSVC linker, giving Rust access to the same mature, well-tested compiler infrastructure used for C and C++ without requiring code changes. _Developers tracking Rust's path into Windows and MSVC tooling can follow these integration details on daily.dev._ ### Has Microsoft made Rust a Tier-1 language internally, and what does that mean? Yes, Microsoft has promoted Rust to Tier-1 status internally, joining C# and TypeScript. Tier-1 status requires a complete tool chain from editors to compilers, integration with Windows and Azure through native SDKs and optimized libraries, and compliance with Microsoft's internal software development life-cycle requirements, signaling deep organizational investment in the language. _Teams weighing Rust adoption for Windows projects can keep tabs on Microsoft's tooling commitments via daily.dev._ ### Is Microsoft's internal Rust compiler back end rustc_codegen_utc available to external developers? No, rustc_codegen_utc is currently internal-only, unlike other Rust codegen back ends such as those for GCC and Cranelift, which are open source. It is already used by more than a hundred Microsoft Rust projects and described as production ready. Microsoft has indicated it will first upstream test and back-end infrastructure work into the public Rust project before any public release. _Developers waiting on official MSVC-Rust tooling can follow release signals like this through daily.dev._ ## Community discussion Top comments from developers on daily.dev. **@f4nt0** · 8 upvotes > Yet another software to Rust.
