In this chapter, we have seen the most probable development lines of the Rust ecosystem in the next few years—support for IDEs and for interactive programming; the maturity of the most popular crates; widespread support of the new asynchronous programming paradigm and its keywords (async and await); further optimization of both the compiler and the generated machine code; and widespread support of embedded systems programming.
We have learned how to write asynchronous code and a possible way to define and use const generics (still unstable at the time of writing).
We have seen that there are quite a lot of application areas where Rust could really shine. Of course, if you are going to use it only for fun, the sky is the limit, but for real-world applications, the ecosystem of libraries and tools can really decide the viability of a programming system. Now, at last, the critical mass of high-quality libraries and tools is about to be reached.
