Struct Store 

pub struct Store { /* private fields */ }

Store

Schema node describing stable IC BTreeMap memories that store:

• primary entity data
• all index data for that entity
• persisted schema metadata for that store

Implementations

impl Store

pub const fn new_stable( def: Def, ident: &'static str, store_name: &'static str, canister: &'static str, stable: StoreStableMemoryConfig, ) -> Self

Build a stable-memory-backed store declaration.

This is the only implemented store constructor in 0.167.

pub const fn def(&self) -> &Def

pub const fn ident(&self) -> &'static str

pub const fn store_name(&self) -> &'static str

pub const fn canister(&self) -> &'static str

pub const fn storage(&self) -> &StoreStorage

Borrow this store’s storage configuration.

pub const fn is_stable_storage(&self) -> bool

Return whether this store is stable-memory-backed.

pub const fn stable_memory_config(&self) -> Option<&StoreStableMemoryConfig>

Borrow stable-memory IDs when this store uses stable storage.

pub const fn stable_data_memory_id(&self) -> u8

pub const fn stable_index_memory_id(&self) -> u8

pub const fn stable_schema_memory_id(&self) -> u8

pub fn stable_data_allocation( &self, memory_namespace: &str, ) -> StableMemoryAllocation

pub fn stable_data_allocation_with_schema_metadata( &self, memory_namespace: &str, schema_metadata: StableMemoryAllocationMetadata, ) -> StableMemoryAllocation

Build the data-memory allocation descriptor with accepted row-layout schema metadata attached for diagnostics.

pub fn stable_index_allocation( &self, memory_namespace: &str, ) -> StableMemoryAllocation

pub fn stable_index_allocation_with_schema_metadata( &self, memory_namespace: &str, schema_metadata: StableMemoryAllocationMetadata, ) -> StableMemoryAllocation

Build the index-memory allocation descriptor with accepted index-catalog schema metadata attached for diagnostics.

pub fn stable_schema_allocation( &self, memory_namespace: &str, ) -> StableMemoryAllocation

pub fn stable_schema_allocation_with_schema_metadata( &self, memory_namespace: &str, schema_metadata: StableMemoryAllocationMetadata, ) -> StableMemoryAllocation

Build the schema-memory allocation descriptor with accepted catalog schema metadata attached for diagnostics.

pub fn stable_allocation( &self, memory_namespace: &str, role: StoreMemoryRole, ) -> StableMemoryAllocation

Trait Implementations

impl Clone for Store

fn clone(&self) -> Store

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Store

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

Formats the value using the given formatter.

impl Serialize for Store

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
