📚 Doc: Example of `after_hook`

[tgsmith61591]

I'm having a really difficult time understanding how to add an after_hook to my World struct. Is there an example in the documentation you can point me to? This is the closest I can find, and the linked source is not too helpful either.

Assuming I have a world as follows:

#[async_trait(?Send)]
impl World for MyCoolWorld {
    type Error = Infallible;

    async fn new() -> Result<Self, Infallible> {
        Ok(Self {
            thing_one: None,
            thing_two: None,
        })
    }
}

And I'm running like so:

    MyCoolWorld::cucumber()
        .run_and_exit("./products")
        .await;

How/where do I attach an after hook? Is it in the World impl block? Is it a builder when I set up the runner? Any example you can provide would be extremely appreciated!

We have a separate book chapter covering Scenario hooks. In your case it would look something like

MyCoolWorld::cucumber()
    .after(|feature, rule, scenario, world| {
        // Hook logic here.
    })
    .run_and_exit("./products")
    .await;
