Enum WalWriterError 

pub enum WalWriterError {
    Closed,
    IoError(String),
    EncodeError(String),
    SequenceViolation {
        expected: u64,
        provided: u64,
    },
    Poisoned,
}

Errors that can occur during WAL writing.

Variants

Closed

The writer was closed.

IoError(String)

I/O error during write.

EncodeError(String)

The event could not be encoded.

SequenceViolation

Sequence number violation (non-increasing or duplicate).

Fields

expected: u64

The expected next sequence number.

provided: u64

The sequence number that was provided.

Poisoned

Writer is permanently poisoned after a truncation-recovery failure. Callers must restart the process.

Trait Implementations

impl Clone for WalWriterError

fn clone(&self) -> WalWriterError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WalWriterError

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

Formats the value using the given formatter.

impl Display for WalWriterError

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

Formats the value using the given formatter.

impl Error for WalWriterError

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 WalWriterError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
