Struct StableMemoryAllocationMetadata 

pub struct StableMemoryAllocationMetadata { /* private fields */ }

Diagnostic schema metadata associated with a stable-memory allocation.

This metadata does not participate in durable allocation identity. The durable identity remains memory_id + stable_key.

Implementations

impl StableMemoryAllocationMetadata

pub const fn from_accepted_schema_contract( schema_version: u32, schema_fingerprint: String, ) -> Self

Build allocation metadata from an accepted schema/catalog authority.

pub const fn absent() -> Self

Build absent allocation metadata for allocations with no accepted schema/catalog authority.

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.

Trait Implementations

impl Clone for StableMemoryAllocationMetadata

fn clone(&self) -> StableMemoryAllocationMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StableMemoryAllocationMetadata

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

Formats the value using the given formatter.

impl PartialEq for StableMemoryAllocationMetadata

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