Why I'm building a new async runtime

On the note of runtimes that are “outside the boxes” of tokio and async-std, I found a really cool generator lib [0] for Rust that uses async&#x2F;await (and has macro API to hide this if you want) but implements an extremely simple runtime that just implements the semantics of generators. I thought it was absolutely genius and underrated.<p>[0] <a href="https:&#x2F;&#x2F;lib.rs&#x2F;crates&#x2F;genawaiter" rel="nofollow">https:&#x2F;&#x2F;lib.rs&#x2F;crates&#x2F;genawaiter</a>

Well that was a tease. I suppose the title didn&#x27;t actual promise me I could read some code, though.

I wonder how it would be if Rust, like Scala came with a very basic executor? For me external crates no matter how popular, seem a no-go because of them constantly changing.
