ReplicaEvent

Enum ReplicaEvent 

Source
pub enum ReplicaEvent {
    Frame(DecodedFrame),
    SnapshotBegin,
    SnapshotChunk(Vec<u8>),
    SnapshotEnd {
        ack_offset: u64,
    },
}
Expand description

Event yielded by ReplicaClient::next_event. A driver loop pattern-matches and applies each:

  • Self::Frame → run through the local dispatcher.
  • Self::SnapshotBegin → caller should reset / prepare the local store for a fresh-from-snapshot fill.
  • Self::SnapshotChunk → append the bytes to the caller’s accumulating snapshot buffer.
  • Self::SnapshotEnd → caller hands the accumulated buffer to kevy_persist::load_snapshot; ReplicaClient has already advanced expected_offset to ack_offset, so the next Self::Frame arrives at ack_offset with no gap.

Variants§

§

Frame(DecodedFrame)

A live mutation frame.

§

SnapshotBegin

Snapshot ship begin marker (+SNAPSHOT\r\n).

§

SnapshotChunk(Vec<u8>)

One snapshot chunk’s payload bytes (RESP bulk string body).

§

SnapshotEnd

Snapshot ship end marker carrying the offset the next live frame will have.

Fields

§ack_offset: u64

The offset the primary’s next_offset was at when the snapshot started. After this event, ReplicaClient::expected_offset equals this value.
