Improving our base example

We’ll create a version of the first example in Chapter 7 since it’s the simplest one to start with. Our only focus is showing how to schedule and drive the runtimes more efficiently.

We start with the following steps:

1. Create a new project and name it a-runtime (alternatively, navigate to ch08/a-runtime in the book’s repository).
2. Copy the future.rs and http.rs files in the src folder from the first project we created in Chapter 7, named a-coroutine (alternatively, copy the files from ch07/a-coroutine in the book’s repository) to the src folder in our new project.
3. Make sure to add mio as a dependency by adding the following to Cargo.toml:

   [dependencies]
   mio = { version = "0.8", features = ["net", "os-poll"] }

4. Create a new file in the src folder called runtime.rs.

We’ll use corofy to change the following coroutine/wait program into its state machine representation that...
