Struct StableMemoryAllocation 

pub struct StableMemoryAllocation { /* private fields */ }

Stable-memory allocation descriptor.

memory_id + stable_key is the durable allocation identity. schema_version + schema_fingerprint is diagnostic metadata only.

Implementations

impl StableMemoryAllocation

pub const fn without_schema_metadata(memory_id: u8, stable_key: String) -> Self

Build an allocation descriptor without schema metadata.

pub const fn with_schema_metadata( memory_id: u8, stable_key: String, schema_metadata: StableMemoryAllocationMetadata, ) -> Self

Build an allocation descriptor with diagnostic schema metadata.

The metadata must come from accepted schema/catalog authority. Generated model fallback metadata is not an allocation metadata authority.

pub const fn memory_id(&self) -> u8

Stable-memory manager ID.

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

Durable stable-memory key.

pub const fn schema_metadata(&self) -> &StableMemoryAllocationMetadata

Diagnostic schema/catalog metadata.

pub const fn schema_version(&self) -> Option<u32>

Accepted schema/catalog version, when known.

pub const fn schema_fingerprint(&self) -> Option<&str>

Accepted schema/catalog fingerprint, when known.

pub fn same_identity_as(&self, other: &Self) -> bool

Compare durable allocation identity only.

Schema metadata is intentionally ignored because metadata changes are diagnostics, not memory replacement.

Trait Implementations

impl Clone for StableMemoryAllocation

fn clone(&self) -> StableMemoryAllocation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StableMemoryAllocation

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

Formats the value using the given formatter.

impl Eq for StableMemoryAllocation

impl PartialEq for StableMemoryAllocation

fn eq(&self, other: &StableMemoryAllocation) -> 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.
