The standard way to make Rust portable would be to statically link with musl, not necessarily use no_std. It depends if you mean for embedded devices though (although Go is listed as portable, so I guess not). I think it's more useful to look at different use cases and possibilities - like having a GC or not and which deployment targets that affects, the possibility for static and dynamic linking, etc.
