ReplicaApply

Enum ReplicaApply 

Source
pub enum ReplicaApply {
    SnapshotBegin,
    SnapshotChunk(Vec<u8>),
    SnapshotEnd {
        ack_offset: u64,
    },
    Frame {
        offset: u64,
        argv: Argv,
    },
}
Expand description

One event delivered from a replica runner to its target shard. Mirrors kevy_replicate::replica::ReplicaEvent except Frame carries an owned Argv (already decoded by the runner) instead of a DecodedFrame { offset, argv } — the offset is gap-checked by the runner on the way in, so the shard doesn’t need it.

Variants§

§

SnapshotBegin

Upstream started shipping a full snapshot. The shard should reset its accumulating snapshot buffer.

§

SnapshotChunk(Vec<u8>)

One chunk of snapshot bytes. The shard appends to its buffer.

§

SnapshotEnd

Upstream finished the snapshot. The shard hands its buffered bytes to kevy_persist::load_snapshot_from (replacing the Store contents) and resumes at ack_offset for live frames.

Fields

§ack_offset: u64
§

Frame

One live mutation frame to be applied via kevy::dispatch (inside a crate::ReplicatedApplyGuard scope so the apply doesn’t re-push into this shard’s downstream ReplicationSource).

Fields

§offset: u64
§argv: Argv
