I'm very excited, since that must mean UWP support for Rust is coming sooner rather than later.
Is there some ongoing work already? I haven't been able to find anything yet, just watched the MWC conference and was kinda surprised by this announcement.
We don't believe it should require a lot of work, but it is still work that needs to be done. I am looking for a developer with Windows expertise (UWP expertise preferred) interested in a short-term contract to add two new Rust targets for arm64 Windows and atom64 Windows and appropriate standard library support; please contact me if that sounds interesting!
