I’m apparently one of the few that use rust and C# as my language duo of choice; our company has gone all in on both. I think the more common combos are golang/rust, js/rust, or python/rust.
But proper support for discriminated unions (and perhaps something better than the emasculated match blocks known as switch expressions) cannot come soon enough for C# to enter the big leagues.
NeoSmart Technologies. Our GUI and web stuff is C# and we’ve been migrating our low-level C and C++ code to rust (no_std rust for most of the C stuff). Some of our existing C/C++ stuff is extremely low level (think bootloaders, virtualization tech, etc) but also cross-platform and we’ve found rust to offer great ergonomics (not to mention safety) without an impedance mismatch under those constraints.
We’re also using rust for cli utilities and non-client-facing backend server stuff.
