AllocationReservationError

Failure to stage a reservation generation.

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.

Integrity(LedgerIntegrityError)

GenerationOverflow

Ledger generation cannot be advanced without overflow.

Fields

generation: u64

Current ledger generation.

TooManyReservations

Reservation count exceeds the usable allocation-slot domain.

Fields

count: usize

Number of reservations in the staged generation.

StableKeySlotConflict

Stable key was historically bound to a different slot.

Fields

stable_key: StableKey

Stable key being reserved.

historical_slot: MemoryManagerSlot

Historical slot for the stable key.

reserved_slot: MemoryManagerSlot

Slot claimed by the reservation.

SlotStableKeyConflict

Slot was historically bound to a different stable key.

Fields

slot: MemoryManagerSlot

Slot being reserved.

historical_key: StableKey

Historical stable key for the slot.

reserved_key: StableKey

Stable key claimed by the reservation.

ActiveAllocation

Allocation already exists as an active record.

Fields

stable_key: StableKey

Active stable key.

slot: MemoryManagerSlot

Active allocation slot.

RetiredAllocation

Allocation was already retired and cannot be reserved.

Fields

stable_key: StableKey

Retired stable key.

slot: MemoryManagerSlot

Retired allocation slot.

Trait Implementations

impl Clone for AllocationReservationError

fn clone(&self) -> Self

impl Eq for AllocationReservationError

impl Error for AllocationReservationError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<LedgerIntegrityError> for AllocationReservationError

fn from(source: LedgerIntegrityError) -> Self
