So when will we get tier 1 debugging support in Visual Studio?

This is very big news, all major OS vendors that also have a role in C and C++ language tooling, now have diversified their options in systems programming languages for greenfield development. Additionally we finally get some public news about the MSVC integration rumors regarding Rust.

Site down, maybe they need port it to use Rust... They use wordpress

Link doesn’t work. What’s a Tier 1 language?

This is great! Hope this trend will continue in the future; using a memory-safe language should be a top priority imo in context of the coming rogue AI swarms.

I guess the big question is whether they are going to open up rustc_codegen_utc for use outside of Microsoft?

With certain rough edges like complex traits and Async aside, rust is an S-tier lang in several domains. Of interest: - Embedded - PC desktop applications - Computationally-intense scientific programming. (Chem, structural bio etc) - OSes, drivers etc - High-performance tasks in general. CPU, GPU, etc. It's not a memory-safety one-trick pony; it's a well-rounded lang which has learned from its predecessors.

Good news they adopted Rust as Tier-1 language. I hope their Weather app stop consuming more than 1GB RAM https://www.notebookcheck.net/Windows-11-s-built-in-Weather-...

Is Microsoft still trying to embrace, extend, extinguish Netscape after all those years? :-)

You gotta have balls or be receiving tons of money to publicly celebrate the sloppiest software company of the decade making your programming language Tier 1 internally.

The big news here is they've replaced LLVM with MSVC's backend.
mgaunard
does it mean there is a rust.net?

If it is a tier-1 language why isn't it supported in Visual Studio?

The text is mostly about rustc_codegen_utc; maybe this should be reflected in the title? Also the use of italics there is rather jarring.

ermm... which are the rust-native libs which enable winrt3.0 native apps?
this_user
Now their broken slop code is at least memory safe.

From the linked Zulip thread ( https://rust-lang.zulipchat.com/#narrow/channel/131828-t-com... ): > We are running different workloads including rustc perf suite. In general the runtime performance is on par with llvm. Not what I would've expected!

This is from rustconf. A lot of the focus at Rustconf this year has been C++ interop, Python Interop, Javascript interop -- it's no longer about "rewrite it in rust", it's about being part of the ecosystem.

M$ choosing Rust might be the strongest argument for picking Go instead

Fable migrated a Go/Wails project for me to Rust/GPUI and it's so much faster, there is the possibility of Rust to gobble up many more projects.
