    },
    LengthOverflow {
        payload_length: u32,

}

Specific validation failure for one WAL record.

Variants

HeaderTruncated

The fixed length/sequence/operation header is torn.

Fields

needed: usize

Required fixed header width.

available: usize

Bytes available at the record offset.

LengthOverflow

The declared payload plus framing cannot fit usize.

Fields

payload_length: u32

Persisted u32 payload length.

BodyTruncated

The record body or checksum is torn.

Fields

payload_length: u32

Persisted u32 payload length.

needed: usize

Complete framed width implied by the header.

available: usize

Bytes available at the record offset.

ChecksumMismatch

The trailing xxh3-64 does not cover the observed record bytes.

Fields

expected: u64

Persisted checksum.

actual: u64

Checksum computed from the header and payload.

record_length: usize

Complete framed width used to find a possible successor.

Trait Implementations

impl Clone for RecordError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RecordError

impl Debug for RecordError

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

Formats the value using the given formatter.

impl Display for RecordError

impl Eq for RecordError

impl Error for RecordError

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 PartialEq for RecordError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
