Does anybody know if that kernel module can execute WASM generated from Go or Rust too?

  Unless they’re doing something non-standard, wasm doesn’t care what language it came from. That said, this claims it relies on emscripten, I think? You can do that with Rust, though it’s not the preferred way. I sure about Go.

    From looking at high_level.h it can instantiate any wasm file, but it seems to need the host code specially integrated. There is a function to instantiate the emscripten runtime, probably code can be added to instantiate the go or rust runtimes.

      Rust doesn’t have a runtime. Well, at least not in the sense of other languages; it’s comparable to C :) Emscripten provides a libc; I wondered if it required it. I guess not.

[ https://en.wikipedia.org/wiki/Crt0 https://en.wikipedia.org/wiki/Crt0 | https://en.wikipedia.org/wiki/Runtime_library https://en.wikipedia.org/wiki/Runtime_library ] Yup. C definitely has a runtime!

          That’s why I said that Rust’s is comparable to C. Both have very, very small ones. Which is what most people mean when they say “no runtime”, since every non-assembly language has some amount of runtime.
