How Rust optimizes async/await I
The issue to stabilize an initial version of async/await in Rust has left final comment period. The feature looks slated to stabilize in an upcoming release, most likely 1.39.
This represents the culmination of an enormous amount of work by people all over the Rust community. But it’s also only the beginning of async/await support in Rust. The feature set being stabilized is a “minimum viable product” for shipping async/await, and we plan to continue to expand the feature set after initial stabilization.
