Struct AllocationRecord 

pub struct AllocationRecord { /* private fields */ }

AllocationRecord

Durable ownership, lifecycle state and latest schema metadata for one stable key. Retaining this record prevents slot reuse after omission or retirement. It is metadata, not a live memory handle or an upgrade audit log.

Implementations

impl AllocationRecord

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

Return the permanent store identity.

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

Return its permanently claimed memory ID.

pub const fn state(&self) -> AllocationState

Return the current lifecycle state.

pub const fn schema(&self) -> &SchemaMetadata

Borrow the latest declared schema metadata; no schema history is kept.
