Nice! That was quicker then I Expected. How far are they with the implementation? Not using rust, but following progress because it is on hackernews so much.

Why does it take so long for swift to have this? Swift + iOS developers really really benefit from it. And there are loads of ios developers compared to rust developers.



It has been usable on nightly since `nightly-2019-05-09` (with https://github.com/rust-lang/rust/pull/60586 )


There seems to have been a lot of groundwork for the Futures specification as well as implementations of underlying features for a while.

Not too dissimilar for JavaScript's async/await syntax which needed support for Promises and Generators as progress points.
