possibility of Providing binaries for Windows arm 64?

Hi,
It would be great to have native Windows ARM64 binaries available. While Windows on ARM can emulate x86 and x64 binaries, this comes with a performance overhead.
Thanks so much for considering this!

I guess I'm open to this, but someone will likely need to do the leg work to add it to the release pipeline and test that it works.

I was hoping I might be able to give this a shot, but it seems Github only offers their Windows ARM64 hosted runners under their Teams and Enterprise plans.

I do, however, see that rust has an arm64 (emulated) target (arm64ec-pc-windows-msvc), so that's at least half way there...

Given that there's currently no free-tier Windows ARM64 hosted instance, I assume this probably isn't on the horizon and would have to be something done locally or maintained separately by someone else until it can be baked into the official test/release pipeline?

That sounds about right assuming that background research is right. And for this to be something I'm willing to accept, I need to 1) be able to maintain it and 2) rely on it to work somewhat reliably. Debugging CI on release failures is a big time sink and probably why I don't do releases more often. So for example, "hey let's depend on this GitHub Action that was just published and has 5 commits" probably won't fly.

There is now a free Windows arm64 runner for GitHub Actions https://blogs.windows.com/windowsdeveloper/2025/04/14/github-actions-now-supports-windows-on-arm-runners-for-all-public-repos/

As a followup, I'd be willing to take a shot at this.

It will be potentially a few weeks before I can get my hands on an arm64 Windows machine for full testing though.

Found a blocker: the rustup action used by ripgrep fails on Windows ARM dtolnay/rust-toolchain#143. Seems that the ARM image doesn't bundle rustup, unlike the x64 image.

That action has now been updated to work on arm64 Windows.
