RowPushMsg

Struct RowPushMsg 

Source
pub struct RowPushMsg {
    pub collection: String,
    pub document_id: String,
    pub payload: Vec<u8>,
    pub op: RowOp,
    pub lsn: u64,
    pub peer_id: u64,
    pub sequence: u64,
}
Expand description

Row post-image push (server → client, 0x15).

Origin sends this for writes that originated on the server — SQL DML, or DDL-managed system rows such as retention policies and alerts — where there is no client-authored CRDT operation to replicate. The peer applies it as a row upsert or delete against its local state.

Deliberately NOT DeltaPushMsg: that message is client → server and its delta field is Loro update bytes. Carrying a MessagePack post-image in it would leave the receiver unable to tell the two encodings apart, and the operation (upsert vs delete) would have to be inferred from an empty payload rather than stated.

Fields§

§collection: String

Collection the row belongs to.

§document_id: String

Row / document ID.

§payload: Vec<u8>

MessagePack-encoded row post-image. Empty for RowOp::Delete.

§op: RowOp

Whether the row was written or removed.

§lsn: u64

Origin-assigned WAL LSN for the write, when known (0 otherwise).

§peer_id: u64

Originating peer / node ID.

§sequence: u64

Per-collection monotonic sequence, for ordering diagnostics.
