This container can hold a type-erased instance of any completion handler,
or it can be empty. When the container holds a value, the implementation
maintains an instance of net::executor_work_guard
for the handler's associated executor. Memory is dynamically allocated to
store the completion handler, and the allocator may optionally be specified.
Otherwise, the implementation uses the handler's associated allocator.
