This is a major milestone for Rust usability and developer productivity.
It was really hard to build asynchronous code until now. You had to clone objects used within futures. You had to chain asynchronous calls together. You had to bend over backwards to support conditional returns. Error messages weren't very explanatory. You had limited access to documentation and tutorials to figure everything out. It was a process of walking over hot coals before becoming productive with asynchronous Rust.
Now, the story is different. Further a few heroes of the community are actively writing more educational materials to make it even easier for newcomers to become productive with async programming much faster than it took others.
Refactoring legacy asynchronous code to async-await syntax offers improved readability, maintainability, functionality, and performance. It's totally worth the effort. Do your due diligence in advance, though, and ensure that your work is eligible for refactoring. Niko wasn't kidding about this being a minimum viable product.
