I'm going through the book Zero To Production In Rust by /u/lukemathwalker and he goes through it step by step. Not once have I needed to use higher level concepts like Cells, RefCells, Boxes (beyond a basic example), etc.
C++ - my favorite language, and, with modern revisions, extremely expressive and readable. There isn't a web server in the standard library, but there are a number of solid open-source choices (e.g., Drogon).
Third party options have been around for nearly a decade now: https://docs.paralleluniverse.co/quasar/

The answer is "pretty easy". Go just import git stuff, most usually straight from github, maybe with some tags (which can be replaced) or date time and some commit prefix (It's also pretty easy to generate new commit with same prefix).
So for instance the bare-bones of the features used to be in the std (nightly), but it was considered too much work and unnecessary for std, as crossbeam-channel has it, and so does e.g. tokio (though tokio's is a lot more general as it's designed to work on futures not just channels, and has features like guards).
Like, for example, some projects importing logrus with a capital L and some with a lowercase L, and go modules having no way to reconcile the two: https://github.com/sirupsen/logrus/issues/553
