+//! \PIThreadPoolWorker is a class that implements a fixed-size pool of worker threads for general-purpose task execution. It
+//! allows starting threads, enqueuing tasks as functors or class member methods, and managing their execution. The class provides methods
+//! to wait for all tasks or specific tasks by ID to complete, as well as to gracefully stop the pool with timeouts. The lifecycle of each
+//! task can be monitored using the taskStarted and taskFinished events. It is a versatile tool for multithreaded asynchronous operations.

+//! PIThreadPoolWorker — это класс, реализующий фиксированный пул рабочих потоков для выполнения задач общего назначения. Он
+//! позволяет запускать потоки, добавлять в очередь задачи в виде функторов или методов класса, а также управлять их выполнением. Класс
+//! предоставляет методы для ожидания завершения всех задач или отдельных задач по их идентификатору, а также для корректной остановки пула
+//! с таймаутами. С помощью событий taskStarted и taskFinished можно отслеживать жизненный цикл каждой задачи. Это универсальный инструмент
+//! для многопоточного асинхронного выполнения операций.
