An error encoding or decoding the log wire format.

Variants

UnexpectedEof

The input ended mid-value (truncated entry or segment).

TrailingBytes

Bytes remained after a value that should have consumed its whole input.

UnknownTag(u8)

An entry tag the op vocabulary does not recognize.

UnresolvedUuid(u64)

A UUID dictionary reference pointed at an index that was never defined.

PkCountMismatch

The number of primary-key values disagreed with the table ID’s PK count.

Fields

expected: usize

PK column count the table ID declares.

got: usize

Number of PK values actually supplied.

ColumnValueMismatch

A column value’s variant did not match the column ID’s declared type.

PkValueMismatch

A primary-key value’s variant did not match the table ID’s declared PK type.

HashMismatch

The recomputed integrity hash did not match the stored one — corruption or tampering.

Fields

expected: u32

Truncated hash read from the entry.

got: u32

Truncated hash recomputed over the decoded bytes.

VarIntOverflow

A varint encoded a value larger than u64.

NonMonotonicDelta

A timestamp delta went backwards, violating the monotonic ordering.

TimestampOverflow

Adding a timestamp delta to the running base overflowed u64.

LengthTooLarge(u64)

An on-wire length/count did not fit in usize on this target.

InvalidUtf8(FromUtf8Error)

A text value was not valid UTF-8.

TextContainsNul

A text value contained an embedded NUL byte, which is disallowed.

BadMagic

The segment’s leading magic bytes did not match the expected app magic.

UnknownSegmentFlags(u8)

The segment flags byte was neither the device nor the server mode value.

MissingUserId

A server-mode entry was missing its required user id.

Io(Error)

An underlying I/O error.

CorruptedLogFile

The log file’s framing was structurally invalid.

Trait Implementations

impl Debug for CodecError

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

Formats the value using the given formatter.

impl Display for CodecError

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

Formats the value using the given formatter.

impl Error for CodecError

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<CodecError> for SyncError

fn from(source: CodecError) -> Self

Converts to this type from the input type.

impl From<Error> for CodecError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<FromUtf8Error> for CodecError

fn from(source: FromUtf8Error) -> Self

Converts to this type from the input type.
