>It does implement AsyncRead and Write, because anything with `Read` and `Write` implements it: https://docs.rs/async-std/0.99.3/async_std/io/trait.Read.html#implementors https://docs.rs/async-std/0.99.3/async_std/io/trait.Read.htm... (that's sadly a little backwards by rustdoc) >impl<T: AsyncRead + Unpin + ?Sized> Read for T { That's saying that anything that impls futures::AsyncRead impls async_std::io::Read. async_std::net::TcpListener does not impl AsyncRead. (Compare with TcpStream and File which do.) >Hyper can best be used with `async_std` through `surf`: https://github.com/rustasync/surf https://github.com/rustasync/surf Sure. You also don't need surf since you can directly use futures's compat executor wrapper around tokio's. The point is that you can't use stuff like hyper without the tokio executor being involved.
