Struct SnapshotMeta 

pub struct SnapshotMeta {
    pub format_version: u32,
    pub node_count: usize,
    pub relationship_count: usize,
    pub wal_lsn: Option<u64>,
}

Metadata reported by save_snapshot / load_snapshot. Kept small and stable so callers can log / diff it without reflecting on the payload.

Fields

format_version: u32

Format version the payload is written in.

node_count: usize

Number of nodes in the snapshot.

relationship_count: usize

Number of relationships in the snapshot.

wal_lsn: Option<u64>

WAL log position captured alongside the snapshot, if any. None for pure (non-checkpoint) snapshots.

Trait Implementations

impl Clone for SnapshotMeta

fn clone(&self) -> SnapshotMeta

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SnapshotMeta

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SnapshotMeta

fn eq(&self, other: &SnapshotMeta) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
