smol VS async-std-hyper

My understanding is you always need a runtime, somethings needs to drive the async flow. But there are others on the market, just not without the.. market domination... of tokio.

https://github.com/smol-rs/smol looks promising simply for being minimal

https://github.com/bytedance/monoio looks potentially easier to work with than tokio

https://github.com/DataDog/glommio is built around linux io_uring and seems somewhat promising for performance reasons.

I haven't played with any of these yet, because Tokio is unfortunately the path of least resistance. And a bit viral in how it's infected tings.

There is also https://github.com/smol-rs/smol which has components which you can compose into your own executor if you still need async IO but your usage patterns don't fit into the general purpose ones that Tokio provides.

If you need precise control over scheduling, consider building something on top of https://github.com/smol-rs/smol

Tokio is a "take what you need" framework, whilst Async-std started as an "everything the box" solution. Today both have a lot of crossover with micro async runtimes like smol becoming the foundation one of framework and optionally usable in the other. The ability to rip out a small dependent sub-crate (dependent package) like smol and use it independently with ease never get's boring, by the way. It's great way to include a test runtime in an async library without forcing the inclusion of a giant async framework.

Helix uses tokio. smol might be a good alternative however.

No, still active on GitHub. What gave you that idea? https://github.com/smol-rs/smol

Found the issue in Google cache. I'm not sure it's really fair of me to post this link here, but equally I think it's better to give the actual text rather than leave it vague.

Here is an example: https://github.com/async-rs/async-std-hyper/blob/master/READ...

You do have to write a ~50 loc compat layer. However, most of the compat layer is due to the fact that tokio's `AsyncRead` and `AsyncWrite` are different from the standard futures crate, which may change in the future [0]. After that, you just have to implement `hyper::Executor` for async-std's `spawn`, and `hyper::Accept` for async-std's `TcpListener`.

Of course, it is not as generic as `Future`, but it is relatively simple. As @steveklabnik mentioned:

> There's a few points here that still need some interop work. The intention is to fix that, but it's non-trivial. We'll get there.
