LedgerIntegrityError

Decoded ledger violates structural allocation-history invariants.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

LimitExceeded

Current structural recovery ceiling exceeded.

Fields

resource: &'static str

limit: usize

DuplicateStableKey

Stable key appears in more than one allocation record.

Fields

stable_key: StableKey

Duplicate stable key.

DuplicateSlot

Allocation slot appears in more than one allocation record.

Fields

slot: MemoryManagerSlot

Duplicate allocation slot.

InvalidRecordGenerationOrder

Allocation record generation ordering is invalid.

Fields

stable_key: StableKey

Stable key whose record is invalid.

first_generation: u64

First generation in the record.

last_seen_generation: u64

stable_key: StableKey

Stable key whose record is invalid.

first_generation: u64

First generation in the record.

retired_generation: u64

EmptySchemaHistory

Allocation record has no schema metadata history.

Fields

stable_key: StableKey

Stable key whose record is invalid.

SchemaHistoryStartMismatch

First schema metadata record does not begin with the allocation record.

Fields

stable_key: StableKey

SchemaHistoryAfterLastSeen

Schema metadata was recorded after the allocation was last observed.

Fields

stable_key: StableKey

Stable key whose record is invalid.

generation: u64

Schema metadata generation.

last_seen_generation: u64

Latest generation that observed the allocation.

DuplicateGeneration

Generation record appears more than once.
