StableMemoryAllocation

Struct StableMemoryAllocation 

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

Stable-memory allocation descriptor.

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

Implementations§

Source§

impl StableMemoryAllocation

Source

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

Build an allocation descriptor without schema metadata.

Source

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.

Source

pub const fn memory_id(&self) -> u8

Stable-memory manager ID.

Source

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

Durable stable-memory key.

Source

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

Diagnostic schema/catalog metadata.

Source

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

Accepted schema/catalog version, when known.

Source

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

Accepted schema/catalog fingerprint, when known.

Source

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.
