async-std has officially been discontinued. We recommend that all users and libraries migrate to the excellentsmol project.

We createdasync-std to demonstrate the value of making a library as close tostd as possible, but async. We think that demonstration was successful, and we hope it will influence future design and development directions of async instd. However, in the meantime, thesmol project came about and provided a great executor and libraries for asynchronous use in the Rust ecosystem. We think that resources would be better spent consolidating aroundsmol, rather than continuing to provide occasional maintenance ofasync-std. As such, we recommend that all users ofasync-std, and all libraries built onasync-std, switch tosmol instead.

In addition to thesmol project as a direct replacement, you may find other parts of the futures ecosystem useful, includingfutures-concurrency,async-io,futures-lite, andasync-compat.
