Enum actyx_sdk::service::SubscribeMonotonicResponse

pub enum SubscribeMonotonicResponse {
    State {
        snapshot: SnapshotData,
    },
    Event {
        event: EventResponse<Payload>,
        caught_up: bool,
    },
    TimeTravel {
        new_start: EventKey,
    },
}

Response to subscribeMonotonic is a stream of events terminated by a time travel

Variants

State

This message may be sent in the beginning when a suitable snapshot has been found for this session. It may also be sent at later times when suitable snapshots become available by other means (if for example this session is computed also on a different node).

Fields of State

snapshot: SnapshotData

Event

This is the main message, a new event that is to be applied directly to the currently known state to produce the next state.

Fields of Event

event: EventResponse<Payload>caught_up: bool

TimeTravel

This message ends the stream in case a replay becomes necessary due to time travel. The contained event key signals how far back the replay will reach so that the consumer can invalidate locally stored snapshots (if relevant).

Fields of TimeTravel

new_start: EventKey
