Enum WalReadError 

pub enum WalReadError {
    Io(Error),
    Header(WalHeaderError),
    InvalidRecoveredRange {
        start: usize,
        end: usize,
        available: usize,
    },
}

WAL recovery failure requiring the caller to stop rather than hide corruption.

Variants

Io(Error)

Filesystem read failed.

Header(WalHeaderError)

A header accepted by replay could not be decoded for resume state.

InvalidRecoveredRange

A replay-derived encoded record range exceeded the WAL image.

Fields

start: usize

First encoded byte of the recovered record.

end: usize

Exclusive end of the recovered record.

available: usize

Complete WAL image length.

Trait Implementations

impl Debug for WalReadError

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

Formats the value using the given formatter.

impl Display for WalReadError

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

Formats the value using the given formatter.

impl Error for WalReadError

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.
