Error types for the 2PC protocol.

Variants

InvalidState(TwoPhaseState)

Attempted operation in wrong protocol state.

PrepareFailed

A participating database failed during prepare.

Fields

db_id: DatabaseId

reason: String

TooManyDatabases

Too many databases attached (exceeds SQLITE_MAX_ATTACHED).

Fields

count: usize

max: usize

DetachWithActiveTransaction

Cannot detach a database with an active transaction.

Fields

db_id: DatabaseId

UnknownDatabase(DatabaseId)

Database is not a participant in this 2PC.

DuplicateDatabase(DatabaseId)

Database was registered more than once for the same 2PC.

MarkerWriteError(String)

I/O error writing commit marker.

WalIndexUpdateError

I/O error during WAL-index update in Phase 2.

Fields

db_id: DatabaseId

reason: String

NotWalMode(DatabaseId)

Database is not in WAL mode (required for 2PC).

Trait Implementations

impl Clone for TwoPhaseError

fn clone(&self) -> TwoPhaseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TwoPhaseError

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

Formats the value using the given formatter.

impl Display for TwoPhaseError

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

Formats the value using the given formatter.

impl Error for TwoPhaseError

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 TwoPhaseError

fn eq(&self, other: &TwoPhaseError) -> 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.
