Struct MemoryManifest 

Source
pub struct MemoryManifest {
    pub schema_version: u32,
    pub revision: u64,
    pub records: Vec<ManifestEntry>,
    pub tombstones: Vec<Tombstone>,
    pub applied: Vec<String>,
}
Expand description

The index written alongside a user’s records.

Fields§

§schema_version: u32

Manifest schema version.

§revision: u64

Monotonic revision, bumped on every commit.

§records: Vec<ManifestEntry>

One entry per record.

§tombstones: Vec<Tombstone>

Deletions, without content.

§applied: Vec<String>

Idempotency keys of commits already applied, most recent last.

Durable, because the retry guarantee has to survive a restart to be worth anything. Reconciliation is at-least-once: if the process dies between a successful commit and the caller learning about it, the retry arrives at a fresh repository. Without these keys it applies a second time, advancing the revision and re-reinforcing evidence — so a crash silently inflates a memory’s confidence.

Bounded: a key only has to outlive the retry window of the transaction that produced it, and the manifest is rewritten on every commit.
