AllocationRecord

Struct AllocationRecord 

Source
pub struct AllocationRecord { /* private fields */ }
Expand description

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§

Source§

impl AllocationRecord

Source

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

Return the stable key that owns this allocation record.

Source

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

Return the durable allocation slot owned by this record.

Source

pub const fn state(&self) -> AllocationState

Return the current allocation lifecycle state.

Source

pub const fn first_generation(&self) -> u64

Return the first committed generation that recorded this allocation.

Source

pub const fn last_seen_generation(&self) -> u64

Return the latest committed generation that observed this allocation.

Source

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

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

Source

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

Return the per-generation schema metadata history.
