Given that rust only works on e.g. cygwin recently (and still does not build many crates: i try to compile jujutsu and failed), this is a big blow to portability IMHO. While I try to like rust, I think making it mandatory for builds of essential tools like git is really too early.
?? I build Jujutsu and many other Rust programs from source on Windows.
Rust has a much better Windows story than C and bash do, due to its heritage as a language built by Mozilla for Firefox.
> Rust has a much better Windows story than C
This is an extremely strong statement. Which is so obviously factually incorrect that I tend to think you might have meant something else.
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.
"work" as in "build"? I would agree with that.
And run.
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.
I meant exactly what I said.
As said before I wasn't complaining about windows, but rather of not so common posix layers like cygwin [0]. Most C posix compliant stuff compiles in my experience.

Right, but Rust makes it so you don't have to use Cygwin. It's one of the great portability advantages of Rust that you can write real Windows programs with it.
I am not really sure if I can follow here. How could a rust compiled program like git honor my cygwin emulated mount points in paths, which I need, when working with other posix compliant software.
I thought that if you invoke a native Windows binary with Cygwin, it translates Unix-looking paths into Windows ones. But it's been a long time since I used Cygwin so I could be wrong.
Git works only on cygwin too?
No, it doesn't. OP meant that the Rust support on Cygwin is bad; it is better with the native Windows API.
I don't quite understand. Why use a janky, lossy Linux emulation layer when you can just target Windows natively?
Cygwin is an ugly hack anyway.
jj has msvc builds and is still tire 1 target maybe something particular about your configuration?
I want it to be cygwin native, i.e. passing calls through the cygwin posix layer and not use the windows binary. Sure I can use the windows binary, but that is a different thing.
