pub struct MemoryRegistry;

MemoryRegistry

Canonical substrate registry for stable memory IDs.

Implementations

impl MemoryRegistry

pub fn reserve_range( crate_name: &str, start: u8, end: u8, ) -> Result<(), MemoryRegistryError>

Reserve an inclusive memory ID range for one crate.

Exact duplicate reservations by the same crate are accepted so init and post-upgrade can share the same bootstrap path.

pub fn register( id: u8, crate_name: &str, label: &str, ) -> Result<(), MemoryRegistryError>

Register one memory ID under an existing owner range.

pub fn register_with_key( id: u8, crate_name: &str, label: &str, stable_key: &str, ) -> Result<(), MemoryRegistryError>

Register one memory ID under an existing owner range using an explicit ABI key.

pub fn export() -> Vec<(u8, MemoryRegistryEntry)>

Export all registered entries (canonical snapshot).

pub fn export_ranges() -> Vec<(String, MemoryRange)>

Export all reserved ranges.

pub fn export_range_entries() -> Vec<MemoryRangeEntry>

Export all reserved ranges with explicit owners.

pub fn export_ids_by_range() -> Vec<MemoryRangeSnapshot>

Export registry entries grouped by reserved range.

pub fn get(id: u8) -> Option<MemoryRegistryEntry>

Retrieve a single registry entry.

pub fn export_historical_ranges() -> Vec<(String, MemoryRange)>

Export all ranges ever recorded in the stable memory layout ledger.

pub fn try_export_historical_ranges() -> Result<Vec<(String, MemoryRange)>, MemoryRegistryError>

Fallibly export all ranges ever recorded in the stable memory layout ledger.

pub fn export_historical() -> Vec<(u8, MemoryRegistryEntry)>

Export all memory IDs ever recorded in the stable memory layout ledger.

pub fn try_export_historical() -> Result<Vec<(u8, MemoryRegistryEntry)>, MemoryRegistryError>

Fallibly export all memory IDs ever recorded in the stable memory layout ledger.
