Errors that can occur in fold operations

Variants

EntryNotFound(Uuid)

Entry not found

InvalidEntryType

Invalid entry type for this fold

Fields

expected: String

The expected entry type name

actual: String

The actual entry type that was provided

Context(String)

Fold context error

Serialization(Error)

Serialization error

Storage(String)

Storage error

LockPoisoned(String)

Internal lock poisoned (concurrent panic)

InvalidInput(String)

Invalid input to a cognitive primitive (Anchor, Selector).

BudgetExhausted

Budget exhausted during selection.

Fields

needed: usize

Budget needed.

budget: usize

Budget available.

AnchorNotFound(String)

Anchor not found during graph traversal.

ComponentMissing(String)

Required component not configured.

IntegrityMismatch

Checkpoint integrity check failed: stored hash does not match recomputed hash.

Fields

id: String

Checkpoint id that failed verification.

stored: String

The hash stored in the checkpoint.

computed: String

The hash recomputed from the loaded state.

CheckpointNotFound(String)

A checkpoint with the given id was not found.

Trait Implementations

impl Debug for FoldError

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

Formats the value using the given formatter.

impl Display for FoldError

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

Formats the value using the given formatter.

impl Error for FoldError

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<Error> for FoldError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<FoldError> for ObjectiveError

fn from(source: FoldError) -> Self

Converts to this type from the input type.
