Struct MemoryManifest 

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

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.

Trait Implementations

impl Clone for MemoryManifest

fn clone(&self) -> MemoryManifest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryManifest

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

Formats the value using the given formatter.

impl Default for MemoryManifest

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MemoryManifest

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MemoryManifest

fn eq(&self, other: &MemoryManifest) -> 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.

impl Serialize for MemoryManifest

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
