A versioned snapshot of the ActionQueue state.

Snapshots capture the state of the ActionQueue system at a point in time and are used to accelerate recovery by providing a starting state for WAL replay. The snapshot format is versioned to support future evolution of the data structures.

Fields

version: u32

The format version of this snapshot.

This version is used to ensure compatibility between the snapshot writer and loader. When the snapshot format changes in a breaking way, this version number should be incremented.

timestamp: u64

The timestamp when this snapshot was taken (Unix epoch seconds).

This timestamp represents the point-in-time at which the snapshot was captured.

metadata: SnapshotMetadata

Metadata about the snapshot for versioning and compatibility.

tasks: Vec<SnapshotTask>

The tasks known at the time of the snapshot.

runs: Vec<SnapshotRun>

The runs known at the time of the snapshot.

engine: SnapshotEngineControl

Engine control projection at snapshot time.

dependency_declarations: Vec<SnapshotDependencyDeclaration>

Dependency declarations at snapshot time.

budgets: Vec<SnapshotBudget>

Budget allocations and consumption records at snapshot time.

subscriptions: Vec<SnapshotSubscription>

Subscription state records at snapshot time.

actors: Vec<SnapshotActor>

Actor registration records at snapshot time.

tenants: Vec<SnapshotTenant>

Tenant records at snapshot time.

role_assignments: Vec<SnapshotRoleAssignment>

Role assignment records at snapshot time.

capability_grants: Vec<SnapshotCapabilityGrant>

Capability grant records at snapshot time.

ledger_entries: Vec<SnapshotLedgerEntry>

Ledger entries at snapshot time.

Trait Implementations

impl Clone for Snapshot

fn clone(&self) -> Snapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Snapshot

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Snapshot

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Snapshot

fn eq(&self, other: &Snapshot) -> 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 Snapshot

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Snapshot

impl StructuralPartialEq for Snapshot
