##### thread_pool::basic_executor_type::query (3 of 3 overloads)

Query the current value of the `outstanding_work` property.

    static constexpr execution::outstanding_work_t query(
        execution::outstanding_work_t );

Do not call this function directly. It is intended for use with the `query` customisation point.

For example:

    auto ex = my_thread_pool.executor();
    if (asio::query(ex, asio::execution::outstanding_work)
          == asio::execution::outstanding_work.tracked)
      ...
