-`.filter_map()`. This is called `filter_map()` because it does `.filter()` and `.map()`. The closure must return an `Option<T>`, and then `filter.map()` takes the value out of each `Option` if it is `Some`. So for example if you were to `.filter_map()` a `vec![Some(9), None, Some(3)]`, it would return `[2, 3]`.

 We will write an example with a `Company` struct. Each company has a `name` so that field is `String`, but the CEO might have recently quit. So the `ceo` field is `Some<String>`. We will `.filter_map()` over some companies to just keep the CEO names.
