Request
the io_context
to invoke the given function object.
template< typename Function, typename OtherAllocator> void defer( Function && f, const OtherAllocator & a) const;
This function is used to ask the io_context to execute the given
function object. The function object will never be executed inside defer().
Instead, it will be scheduled to run on the io_context.
If the current thread belongs to the io_context, defer() will delay scheduling the function object
until the current thread returns control to the pool.
The function object to be called. The executor will make a copy of the handler object as required. The function signature of the function object must be:
