Even what IS tokio for us casual observers would be nice to know! Futures I can infer, but tokio? I have no clue and the article doesn't help.
The main website shows this off, and it's the project's blog. I don't think every single post on a development blog needs to re-hash the whole project.
Except that takes a specific tokio package for each operation rather than being a kitchen sink of everything in one crate.
Might help illuminate some things?
