12 * A thread worker used by a poolifier `ThreadPool`.
14 * When this worker is inactive for more than the given `maxInactiveTime`,
15 * it will send a termination request to its main thread.
17 * If you use a `DynamicThreadPool` the extra workers that were created will be terminated,
18 * but the minimum number of workers will be guaranteed.
20 * @typeParam Data - Type of data this worker receives from pool's execution. This can only be serializable data.
21 * @typeParam Response - Type of response the worker sends back to the main thread. This can only be serializable data.
