Class to inform the io_context

Description |
|---|---|
|
Get the io_context associated with the work. |
|
|
Constructor notifies the io_context that work is starting. |
|
|
Destructor notifies the io_context that the work is complete. |
The work class is used to inform the io_context
when work starts and finishes. This ensures that the io_context
object's run() function will not exit while work is underway,
and that it does exit when there is no unfinished work remaining.
The work class is copy-constructible so that it may be used as a data member in a handler class. It is not assignable.
