Struct StoreStorageCapabilities 

pub struct StoreStorageCapabilities { /* private fields */ }

Storage capability descriptor derived from a store storage mode.

Capabilities describe storage policy. They are not allocation identity. Stable allocation identity remains memory_id + stable_key; heap allocation identity remains absent.

Implementations

impl StoreStorageCapabilities

pub const fn stable() -> Self

Capability descriptor for stable-memory stores.

pub const fn heap() -> Self

Capability descriptor for heap stores.

pub const fn storage_mode(self) -> StoreStorageMode

Diagnostic storage mode. Policy code should use the capability axes.

pub const fn allocation_identity(self) -> AllocationIdentityCapability

Stable allocation identity capability.

pub const fn durability(self) -> StoreDurability

Durability capability.

pub const fn recovery(self) -> StoreRecoveryCapability

Recovery capability.

pub const fn commit_participation(self) -> CommitParticipation

Commit participation capability.

pub const fn schema_metadata(self) -> SchemaMetadataCapability

Schema metadata persistence capability.

pub const fn relation_source(self) -> RelationSourceCapability

Relation source capability.

pub const fn relation_target(self) -> RelationTargetCapability

Relation target capability.

pub const fn live_validation(self) -> LiveValidationCapability

Live validation capability.

pub const fn has_allocation_identity(self) -> bool

Return whether stable allocation identity is present.

pub const fn participates_in_durable_commit(self) -> bool

Return whether mutations participate in durable commit.

pub const fn is_volatile(self) -> bool

Return whether the store is volatile.

Trait Implementations

impl Clone for StoreStorageCapabilities

fn clone(&self) -> StoreStorageCapabilities

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StoreStorageCapabilities

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

Formats the value using the given formatter.

impl PartialEq for StoreStorageCapabilities

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

impl Serialize for StoreStorageCapabilities

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
