Struct AllocationRecord 

pub struct AllocationRecord { /* private fields */ }

AllocationRecord

Durable ownership record for one stable key.

Records are historical facts, not live handles. Fields are private so stale or invalid ownership state cannot be assembled through public struct literals; use accessors for diagnostics and ledger methods for mutation.

Implementations

impl AllocationRecord

pub const fn stable_key(&self) -> &StableKey

Return the stable key that owns this allocation record.

pub const fn slot(&self) -> &AllocationSlotDescriptor

Return the durable allocation slot owned by this record.

pub const fn state(&self) -> AllocationState

Return the current allocation lifecycle state.

pub const fn first_generation(&self) -> u64

Return the first committed generation that recorded this allocation.

pub const fn last_seen_generation(&self) -> u64

Return the latest committed generation that observed this allocation.

pub const fn retired_generation(&self) -> Option<u64>

Return the generation that explicitly retired this allocation, if any.

pub fn schema_history(&self) -> &[SchemaMetadataRecord]

Return the per-generation schema metadata history.

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.
