Struct SnapshotMeta 

Source 
pub struct SnapshotMeta<NID, N>
where
    NID: NodeId,
    N: Node,
{
    pub last_log_id: Option<LogId<NID>>,
    pub last_membership: StoredMembership<NID, N>,
    pub snapshot_id: String,
}
Expand description

The metadata of a snapshot.

Including the last log id that included in this snapshot, the last membership included, and a snapshot id.

Fields§

§last_log_id: Option<LogId<NID>>

Log entries upto which this snapshot includes, inclusive.

§last_membership: StoredMembership<NID, N>

The last applied membership config.

§snapshot_id: String

To identify a snapshot when transferring. Caveat: even when two snapshot is built with the same last_log_id, they still could be different in bytes.
