# whorl - A single file, std only, async Rust executor

whorl was created to teach you how async executors work in Rust. It is not the

fastest executor nor is it's API perfect, but it will teach you about them and

how they work and where to get started if you wanted to make your own. It's

written in a literate programming style such that reading it from beginning to

end tells you a story about how it works or you can read parts of it in chunks

depending on what you want to get out of it.

You can read it all [online here on GitHub](https://github.com/mgattozzi/whorl/blob/main/src/lib.rs)

or you can clone the repo yourself and open up `src/lib.rs` to read through it

in your favorite text editor or play around with it and change things. All of

the code is licensed under the `MIT License` so you're mostly free to do with it

as you wish. If you want to make the next `tokio` or just make something for fun

you can do that.

If you just want to see it in action an example test program is included as part

of the file. You can see it's output by just running:

```bash

cargo test -- --nocapture

```

Which should look something like this:

```bash

whorl on  main [!⇡] is 📦 v0.1.0 via 🦀 v1.56.0 took 10s

❯ cargo test -- --nocapture
