Struct ReplicationSnapshot 

pub struct ReplicationSnapshot {
    pub format_version: u16,
    pub last_index: u64,
    pub records: Vec<ReplicationSnapshotRecord>,
    pub checksum: String,
}

Integrity-protected portable image of a replication log.

Fields

format_version: u16

Snapshot encoding version.

last_index: u64

One-based index of the final record.

records: Vec<ReplicationSnapshotRecord>

Replication records in log order.

checksum: String

SHA-256 checksum over version, index, sequences, and payloads.

Implementations

impl ReplicationSnapshot

pub fn try_from_records( records: impl IntoIterator<Item = (u64, Vec<u8>)>, ) -> SyncResult<Self>

Creates a validated snapshot while taking ownership of every payload.

Payload allocations are moved into the snapshot instead of cloned. The same record-count, record-size, sequence-uniqueness and checksum contracts used by durable replication logs are applied.

pub fn validate(&self) -> SyncResult<()>

Validates this snapshot without cloning record payloads.
