AllocationValidationError

Failure to validate declarations against policy and historical ledger facts. Construction and decoding establish snapshot invariants; recovery establishes ledger integrity before this boundary.

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.

Policy(P)

Policy adapter rejected the declaration.

StableKeySlotConflict

Stable key was historically bound to a different slot.

Fields

stable_key: StableKey

Stable key that was redeclared.

historical_slot: MemoryManagerSlot

Historical slot for the stable key.

declared_slot: MemoryManagerSlot

Slot claimed by the current declaration.

SlotStableKeyConflict

Slot was historically bound to a different stable key.

Fields

slot: MemoryManagerSlot

Slot claimed by the current declaration.

historical_key: StableKey

Historical stable key for the slot.

declared_key: StableKey

Stable key claimed by the current declaration.

RetiredAllocation

Current declaration attempted to revive a retired allocation.

Fields

stable_key: StableKey

Retired stable key.

slot: MemoryManagerSlot

Retired allocation slot.

Trait Implementations

impl<P: Clone> Clone for AllocationValidationError<P>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

impl<P> Error for AllocationValidationError<P>

where Self: Debug + Display,

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
