AllocationStageError

Failure to stage a validated allocation 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.

StaleValidatedAllocations

Validated declarations were produced against a different ledger generation.

Fields

validated_generation: u64

Generation carried by the validated allocation session.

ledger_generation: u64

Current ledger generation.

GenerationOverflow

Ledger generation cannot be advanced without overflow.

Fields

generation: u64

Current ledger generation.

TooManyDeclarations

Declaration count does not fit in durable generation diagnostics.

Fields

count: usize

Number of declarations in the staged generation.

InvalidSchemaMetadata

A staged declaration carries invalid schema metadata.

Fields

stable_key: StableKey

Stable key whose schema metadata is invalid.

error: SchemaMetadataError

Schema metadata validation error.

StableKeySlotConflict

Stable key was historically bound to a different slot.

Fields

stable_key: StableKey

Stable key being declared.

historical_slot: Box<AllocationSlotDescriptor>

Historical slot for the stable key.

declared_slot: Box<AllocationSlotDescriptor>

Slot claimed by the declaration.

SlotStableKeyConflict

Slot was historically bound to a different stable key.

Fields

slot: Box<AllocationSlotDescriptor>

Slot being declared.

historical_key: StableKey

Historical stable key for the slot.

declared_key: StableKey

Stable key claimed by the declaration.

RetiredAllocation

Current declaration attempted to revive a retired allocation.

Fields

stable_key: StableKey

Retired stable key.

slot: Box<AllocationSlotDescriptor>

Retired allocation slot.

UnexpectedActiveAllocationConflict

Internal claim validation reported an active-allocation conflict where declaration staging expected only move, reuse, or tombstone conflicts.

Fields

stable_key: StableKey

Active stable key.

slot: Box<AllocationSlotDescriptor>

Active allocation slot.

Trait Implementations

impl Clone for AllocationStageError

fn clone(&self) -> AllocationStageError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AllocationStageError

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

Formats the value using the given formatter.

impl Display for AllocationStageError

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

Formats the value using the given formatter.

impl Eq for AllocationStageError

impl Error for AllocationStageError

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<P> From<AllocationStageError> for RuntimeBootstrapError<P>

fn from(source: AllocationStageError) -> Self

Converts to this type from the input type.

impl PartialEq for AllocationStageError

fn eq(&self, other: &AllocationStageError) -> 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.
