Struct AllocationLedger 

pub struct AllocationLedger {
    pub ledger_schema_version: u32,
    pub physical_format_id: u32,
    pub current_generation: u64,
    pub allocation_history: AllocationHistory,
}

AllocationLedger

Durable root of allocation history.

Fields

ledger_schema_version: u32

Ledger schema version.

physical_format_id: u32

Physical encoding format identifier.

current_generation: u64

Current committed generation selected by recovery.

allocation_history: AllocationHistory

Historical allocation facts.

Implementations

impl AllocationLedger

pub fn validate_integrity(&self) -> Result<(), LedgerIntegrityError>

Validate structural ledger invariants before recovery or commit.

pub fn stage_validated_generation( &self, validated: &ValidatedAllocations, committed_at: Option<u64>, ) -> Self

Return a copy of the ledger with validated recorded as the next generation.

This is a pure logical update. Physical atomicity is the responsibility of the substrate commit protocol.

pub fn stage_reservation_generation( &self, reservations: &[AllocationDeclaration], committed_at: Option<u64>, ) -> Result<Self, AllocationReservationError>

Return a copy of the ledger with reservations recorded as the next generation.

This is a pure logical update. The caller is responsible for applying framework policy before staging reservations.

pub fn stage_retirement_generation( &self, retirement: &AllocationRetirement, committed_at: Option<u64>, ) -> Result<Self, AllocationRetirementError>

Return a copy of the ledger with one explicit retirement committed.

Trait Implementations

impl Clone for AllocationLedger

fn clone(&self) -> AllocationLedger

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AllocationLedger

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AllocationLedger

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AllocationLedger

fn eq(&self, other: &AllocationLedger) -> 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 AllocationLedger

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for AllocationLedger
