Step 1 – Improving our runtime design by adding a Reactor and a Waker

In this step, we’ll make the following changes:

  1. Change the project structure so that it reflects our new design.
  2. Find a way for the executor to sleep and wake up that does not rely directly on Poll and create a Waker based on this that allows us to wake up the executor and identify which task is ready to progress.
  3. Change the trait definition for Future so that poll takes a &Waker as an argument.


You’ll find this example in the ch08/b-reactor-executor folder. If you follow along by writing the examples from the book, I suggest that you create a new project called b-reactor-executor for this example by following these steps:

1. Create a new folder called b-reactor-executor.

2. Enter the newly created folder and write cargo init.

3. Copy everything in the src folder in the previous example, a-runtime, into the src folder of a new project...
