Variants

InvalidIdentifierBounds

IdentifiersExhausted

SequenceExhausted

CommitOrder

Fields

previous: CommitSequence

next: CommitSequence

WriteConflict

Fields

mutation: usize

expected: Option<CommitSequence>

actual: Option<CommitSequence>

ReadConflict

Fields

dependency: usize

expected: Option<CommitSequence>

actual: Option<CommitSequence>

SerializationConflict

Fields

transaction: SerializableTransactionId

WrongSerializableCoordinator

CommitSnapshotChanged

The provider verified a pending receipt under exclusive admission, but evaluated derived effects used an earlier committed snapshot. Only those pure effects may be prepared again.

Implementations

impl VersionError

pub fn into_storage_error(self) -> StorageBackendError

Preserve resource and provider diagnostics through existing storage APIs.

Trait Implementations

impl Debug for VersionError

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

Formats the value using the given formatter.

impl Display for VersionError

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

Formats the value using the given formatter.

impl Error for VersionError

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.
