Job manager executing only the latest scheduled job, delayed.
Throttler can be used to simplify search functionality implementation, where after inputing a query a search request is executed. But executing a request on each key press would be quite an overhead, and the throttler comes to the rescue.
class SearchWorker {
let throttler = Throttler(delay: .miliseconds(500))
func search(query: String, completion: (SearchResults) -> Void) {
throttler.execute {
// this block will get executed after `0.5` seconds.
// if `search` is called multiple times during this period, only the latest call will be dispatched
self.performApiRequest(query: query, completion: completion)
}
}
