As a Windows user, I find random Rust projects work on Windows far more often than random C ones, even if the authors didn’t make a specific attempt to support Windows.
My colleague Bryan Cantrill, famously a huge Unix guy, once said to me “if you had told me that projects I write would just work on Windows at the rate they do, I wouldn’t have believed you.” When I started at Oxide I had to submit like one or two patches to use Path instead of appending strings and that was it, for my (at the time) main work project.
This is an extremely strong statement. Which is so obviously factually incorrect that I tend to think you might have meant something else.
