Struct LegacySnapshot

Source

pub struct LegacySnapshot {
    pub snapshot_id: u64,
    pub kind: SnapshotKind,
    pub created_at_secs: u64,
    pub entries: Vec<LegacySnapshotEntry>,
    pub parent_id: Option<u64>,
}

Expand description

An immutable point-in-time view of a set of storage blocks (legacy API).

Fields§

§snapshot_id: u64

Unique, monotonically-increasing identifier assigned by the manager.

§kind: SnapshotKind

What subset of blocks this snapshot captures.

§created_at_secs: u64

Unix timestamp (seconds since epoch) at which this snapshot was taken.

§entries: Vec<LegacySnapshotEntry>

The block entries recorded in this snapshot.

§parent_id: Option<u64>

For Incremental and Differential snapshots, the id of the parent snapshot this one is relative to. Always None for Full snapshots.
