Enum WalDecodeError 

pub enum WalDecodeError {
    Truncated {
        expected: usize,
        actual: usize,
    },
    BadMagic,
    UnsupportedVersion(u32),
    ChecksumMismatch,

}

Error returned when a logical WAL record fails to decode or verify.

Variants

Truncated

The record is shorter than its header or declared payload.

Fields

expected: usize

Total length required by the header/payload.

actual: usize

Actual bytes available.

BadMagic

The record does not begin with the expected magic.

UnsupportedVersion(u32)

The record uses a framing version this build does not support.

ChecksumMismatch

The record’s CRC does not match its contents.

OversizedPayload(u32)

The declared payload exceeds the 64 MiB record ceiling.

Trait Implementations

impl Debug for WalDecodeError

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

Formats the value using the given formatter.

impl Display for WalDecodeError

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

Formats the value using the given formatter.

impl Error for WalDecodeError

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>)
