The send member function
allows you to send a message of any type to an actor.
template<typename Msg> void send(Msg&& msg);
Post a copy of msg
on the internal message queue of the actor, constructed with Msg m(std::forward<Msg>(msg)).
std::bad_alloc if the memory required
to post the message could not be allocated; jss::poisoned_queue if the
actor has already completed execution; any exceptions thrown by
the copy or move constructor of Msg.
The completion of the call to send() synchronizes-with
a call to receive()
that receives the posted message.
Multiple threads may call send() concurrently on the same actor
without external synchronization. If a call to send() from one thread happens-before
a call to send() from another thread then the
message sent by the first thread will be received before the message
sent from the second. If two threads call send() and neither call happens-before
the other then the order in which those messages will be received
is unspecified.
