Variants

Io(Error)

A filesystem operation failed.

BadMagic

A frame does not start with the Hyphae magic bytes.

Fields

offset: u64

Frame offset.

UnsupportedVersion

A frame uses a disk version this binary cannot decode.

Fields

offset: u64

Frame offset.

found: u16

Version found on disk.

supported: u16

Version understood by this binary.

UnknownFrameKind

A frame kind is not part of this format version.

Fields

offset: u64

Frame offset.

kind: u8

Raw kind byte.

UnsupportedFlags

Reserved frame flags are nonzero.

Fields

offset: u64

Frame offset.

flags: u8

Raw flag byte.

PayloadTooLarge

A payload exceeds the per-frame allocation limit.

Fields

length: usize

Requested or decoded length.

maximum: usize

Configured maximum.

InvalidSequence

A frame sequence is not exactly the previous sequence plus one.

Fields

offset: u64

Frame offset.

expected: u64

Expected sequence.

found: u64

Sequence found.

PreviousDigestMismatch

The digest chain does not connect to the prior frame.

Fields

sequence: u64

Invalid frame sequence.

ChecksumMismatch

The CRC32C integrity check failed.

Fields

sequence: u64

Invalid frame sequence.

DigestMismatch

The BLAKE3 frame digest failed.

Fields

sequence: u64

Invalid frame sequence.

MalformedTransaction

A transaction descriptor has the wrong length or contents.

Fields

sequence: u64

Invalid frame sequence.

TransactionBoundary

An operation or commit appeared without its matching begin frame.

Fields

kind: &'static str

Frame kind being validated.

sequence: u64

Invalid frame sequence.

TransactionContentMismatch

The committed operation count or digest differs from its descriptor.

Fields

sequence: u64

Invalid commit sequence.

IdempotencyConflict

A transaction identifier was reused for different contents.

Fields

transaction_id: Uuid

Reused identifier.

EmptyTransaction

A transaction cannot be committed without at least one operation.

TooManyOperations

The operation count cannot be represented by the disk format.

SequenceExhausted

The sequence space has been exhausted.

InvalidAnchor

A segment base sequence and digest do not form a canonical anchor.

Poisoned

The writer observed an uncertain I/O result and must be reopened.

Trait Implementations

impl Debug for LogError

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

Formats the value using the given formatter.

impl Display for LogError

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

Formats the value using the given formatter.

impl Error for LogError

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 LogError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<LogError> for StorageError

fn from(source: LogError) -> Self

Converts to this type from the input type.
