## Usage

```swift

// MARK: Example 1

typealias Page = [Int]

typealias Callback = () -> Void

// take previous Page, and create next one

let nextPage = { (previousPage: Page?) -> Observable in

let last = previousPage?.last ?? 0

return Observable.just([last + 1, last + 2, last + 3])

}

// return true if there are more pages to be emitted

let hasNext = { (page: Page) -> Bool in

guard let last = page.last else { return true }

return last < 10 // arbitrary condition for the demo

}

// create the pager

let trigger = PublishSubject()

let page$ = Observable.page(nextPage, while: hasNext, when: trigger)

let next = trigger.onNext

page$.subscribe(onNext: { print($0) })

// print [1, 2 ,3]

next() // print [4, 5, 6]

next() // print [7, 8, 9]

next() // print [10, 11, 12]

// MARK: Example 2 (page from array)

Observable

.page(Array(1...10), by: 3, when: trigger)

.subscribe(onNext: { print($0) })

// print [1, 2 ,3]

next() // print [4, 5, 6]

next() // print [4, 5, 6]

next() // print [10]

```
