AllocationRecord

Durable ownership record for one stable key.

Fields

stable_key: StableKey

Stable key that owns the slot.

slot: AllocationSlotDescriptor

Durable allocation slot owned by the key.

state: AllocationState

Current allocation lifecycle state.

first_generation: u64

First committed generation that recorded this allocation.

last_seen_generation: u64

Latest committed generation that observed this allocation declaration.

retired_generation: Option<u64>

Generation that explicitly retired this allocation.

schema_history: Vec<SchemaMetadataRecord>

Per-generation schema metadata history.

Implementations

impl AllocationRecord

pub fn from_declaration( generation: u64, declaration: AllocationDeclaration, state: AllocationState, ) -> Self

Create a new allocation record from a declaration.

pub fn reserved(generation: u64, declaration: AllocationDeclaration) -> Self

Create a new reserved allocation record from a declaration.

Trait Implementations

impl Clone for AllocationRecord

fn clone(&self) -> AllocationRecord

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AllocationRecord

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AllocationRecord

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AllocationRecord

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

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 AllocationRecord

impl StructuralPartialEq for AllocationRecord
