Apparently outside WinUI efforts, that many don't care about, there isn't much going on, the Rust action is all on Azure side.
Rust for systems programming, C# for non-performing bound tasks (control panels, launchers, light gaming, GUI's on top of Windows CLI tools) and C++ for raw performance. And, still, I won't let any modern codec for A/V to be written in C/C++ for obvious reasons. And I am a diehard Unix+C user in the infamous N270 netbook. but dark times with automatic AI attacks are comming ahead. That's why I migrated from Mutt to Aerc, while keeping my Maildir and msmtp/isync.
At least I will be able to reencode potential harmful media for 420p/720@30FPS for the netbook in the NUC if FFMPEG (or FFMPEG based tools) were converted into Rust without hitting several vulns, because they will be everywhere:
- qemu/libvirt
- imagemagick/graphicsmagick, both the tools and libraries
- any libav* codec/parser
- libpng/libgif and similar
- zip/7z/tar/pax
- PS/PDF, of course. Especially PS, for obvious reasons.
- Some DOC/XLS formats pre DOCX are raw memory dumps and maybe they can be partially executed.
- Some other formats can act like a mini-VM bytecode too, such as RAR.
I even compiled Bubblewrap too so I can jail some of these, and yet I don't trust them 100%. Some recent exploits bypassed the chroot like nothing.
C# to me compares to Java and Kotlin (they have a large runtime or VM and implement GC).
Rust compares to C, C++, Zig or Odin (compile to native, memory is more self-managed).
Other than a few examples given in the past, the Rust adoption among WinDev doesn't seem to be really taking off like in Azure.
Indeed C# is getting more low level coding features, and the unsafe memory model is being redone in .NET 11 for a reason.
