On: How Rust optimizes async/await

[saghm]

> Rust kind of skipped the whole non-blocking thing and went straight to tokio, then had to backtrack a little to mio+tokio, then when mio is only half way jupmed to async/await.

Not sure exactly what you mean here; mio predates tokio by a couple years, and has been possible to use standalone since before tokio ever became a thing.

[devit → saghm]

Early versions of mio had a bunch of non-essential things like a timer wheel built-in, that were later removed.

[rapsey → devit]

What does tokio have to do with that?
