What are the features you expect Rust to gain between now and 5 years from now?

As for major language features I remember async await from a year ago, const generics recently and that’s it. If you can remember more features that fundamentally changed how we write code, please let us know.

I don’t think many features are expected in the near future apart from maybe generic associated types. But not any time soon either.

I think you might be seeing releases every six weeks and assume that each of these bring massive changes. They don’t. Each is a small iterative improvement. Take a look at the Rust release notes if you like.



Generators is one.

Custom allocators and anything else required to build bare-metal software.

Compiling Rust itself, especially std::core. I hit that wall when trying to cross-compile using stable Rust that came with my distro.


Non-Lexical Lifetimes were a pretty big quality-of-life improvement. The question mark operator was also quite nice.


NLL landed in 1.31, in 2018, and ? landed in 1.13, in 2016. two and a half and five years ago :)
