Maybe a little weird question but do you maybe know a smart watch that can run rust? I got running Egui on my Galaxy Watch 4 with WearOS and I’m thinking if any other watch (other than Galaxy and Pixel) can do that?

    Anything that can run C++ should be able to run Rust if you use the LLVM backend, perhaps except when a watch uses musl libc and you rely on some glibc-only call in your program. afaik the only physical devices shipping with musl are car infotainment systems based on l4 kernels and networking hardware (OpenWRT).

      Your answer wanders a bit unnecessarily IMHO.

      • no-std Rust has no run-time dependencies of its own.
      • std Rust runtime-requirements are basically libc, a heap allocator, and a threading library. Many implementations on many OSes are already supported, including musl on Linux. And what’s not supported can theoretically be so in the future.
      • Code generation at build-time is dependent on LLVM, with cranelift and (soon) GCC available as not fully mature alternatives.
      • 3rd party code/crates may impose additional requirements.

        I did not really mean that out of the box there would be incompatibilities, more likely within unsafe blocks and external crates
