LedgerCommitStore

Struct LedgerCommitStore 

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

LedgerCommitStore

Generation-scoped allocation ledger commit store.

This type owns the logical commit lifecycle and the crate-owned CBOR ledger encoding. It deliberately does not own stable-memory IO; that remains the substrate or framework owner’s responsibility.

This store commits allocation ledger generations. It does not open stable-memory handles and does not allocate application slots.

Implementations§

Source§

impl LedgerCommitStore

Source

pub const fn physical(&self) -> &DualCommitStore

Borrow the protected physical commit store for diagnostics.

Source

pub fn recover(&self) -> Result<RecoveredLedger, LedgerCommitError>

Recover the authoritative allocation ledger using the native CBOR ledger codec.

Source

pub fn recover_or_initialize( &mut self, genesis: &AllocationLedger, ) -> Result<RecoveredLedger, LedgerCommitError>

Recover the authoritative ledger, or explicitly initialize an empty store.

Initialization is allowed only when no physical commit slot has ever been written. Corrupt or partially written stores fail closed even when a genesis ledger is supplied.

Source

pub fn commit( &mut self, ledger: &AllocationLedger, ) -> Result<RecoveredLedger, LedgerCommitError>

Commit one logical allocation ledger generation through the native CBOR ledger codec.
