I can’t target msvc or aarch-64-apple-* and compile a binary on Linux, without resorting to significant amounts of rectal dentistry.

Can’t you just replace the “cargo” command with “cross”

    cross build —-target=…

Cross-building for Apple is possible, but it's far from smooth with many steps that you have to figure out by yourself unfortunately.

I use this which seems to work well for my projects. Particularly their docker image.

I've built .exes for Windows just fine on Linux. I don't know about Apple stuff, though, I don't think there's any built-in Linux tooling to submit an executable for Apple's signature scheme.

It's not quite as seamless as in Go to be fair. But it does mean you can write Rust instead of Go.

And .NET

You can in fact also do it in C
