If you want to build web services, I'd go with Go. It has an http library in its standard library. It generally has a bigger standard library. Rust has a bigger stdlib than say C++, but it's still pretty anemic by the standards of modern languages. Go also compiles a lot faster than Rust, which is a major point. If you like functional programming, or want to write embedded software, or high-performance software, I'd go with Rust. All those things are a lot easier in Rust. Personally, I use Go for scripting and Rust for big projects, because Go compiles fast enough, has a nicer stdlib and dependency management than Python; while for big project my natural tendency to think functionally would make it too annoying having to translate simple concepts into programs twice as long as they need to be, expressing what they're doing very indirectly. But I don't write web services, so that's a different story.
