    CorruptState {
        msg: String,

}

Errors that can occur while reading or writing the commit log.

Variants

Conflict

The caller’s expected_version does not match the CURRENT pointer.

Fields

expected: u64

The version the caller expected to be current.

found: u64

The actual current version found.

backtrace: Backtrace

Backtrace for debugging.

Storage

Underlying storage error while working with the log or CURRENT file.

Backtraces are delegated to the inner StorageError.

Fields

source: StorageError

Underlying storage error returned by the storage backend.

UnsupportedFormatVersion

Table metadata uses a format version this reader cannot interpret.

Fields

expected: u32

The only table format version this reader supports.

found: u64

Version found in persisted table metadata.

AmbiguousOutcome

A commit operation failed and its newly-created commit file may remain.

Fields

commit_path: String

Path of the commit file that may remain unpublished.

operation_error: Box<StorageError>

Write, sync, or publish failure that triggered cleanup.

cleanup_error: Box<StorageError>

Failure encountered while removing the unpublished commit file.

backtrace: Backtrace

Backtrace for debugging.

CorruptState

The log or CURRENT file is in an unexpected / malformed state.

Fields

msg: String

A description of the corrupt state.

backtrace: Backtrace

Backtrace for debugging.

Trait Implementations

impl Debug for CommitError

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

Formats the value using the given formatter.

impl Display for CommitError

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

Formats the value using the given formatter.

impl Error for CommitError

where Self: Debug + Display,

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 ErrorCompat for CommitError

fn backtrace(&self) -> Option<&Backtrace>

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.
