Classes | |
struct | ack_batch |
Cumulatively acknowledges received batches and signalizes new demand from a sink to its source. More... | |
struct | ack_open |
Acknowledges a previous open message and finalizes a stream handshake. More... | |
struct | batch |
Transmits stream data. More... | |
struct | close |
Orderly shuts down a stream after receiving an ACK for the last batch. More... | |
struct | drop |
Informs a source that a sink orderly drops out of a stream. More... | |
struct | forced_close |
Propagates a fatal error from sources to sinks. More... | |
struct | forced_drop |

Public Types | |
using | content_alternatives = detail::type_list< open, ack_open, batch, ack_batch, close, drop, forced_close, forced_drop > |
Lists all possible options for the payload. | |
using | content_type = variant< open, ack_open, batch, ack_batch, close, drop, forced_close, forced_drop > |
Stores one of content_alternatives . | |

Public Attributes | |
stream_id | sid |
ID of the affected stream. | |

Address of the sender. More... | |

Palyoad of the message. | |
Stream communication messages for handshaking, ACKing, data transmission, etc.
actor_addr caf::stream_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.
