Stream messages that travel downstream, i.e., batches and close messages.
actor_addr caf::downstream_msg::sender |
Address of the sender.
Identifies the up- or downstream actor sending this message. Note that abort messages can get send after sender
already terminated. Hence, current_sender()
can be nullptr
, because no strong pointers can be formed any more and receiver would receive an anonymous message.
