Enum TwoPhaseError 

pub enum TwoPhaseError {
    Plan(TwoPhasePlanError),
    Journal(TwoPhaseJournalError),
    Prepare {
        step: usize,
        prepared: usize,
        source: ClientError,
    },
    Commit {
        step: usize,
        committed: usize,
        source: ClientError,
    },
}

Why a cross-shard 2PC attempt failed.

Variants

Plan(TwoPhasePlanError)

The coordinator plan was invalid (duplicate keys, empty steps, etc.).

Journal(TwoPhaseJournalError)

Durable journal read/write failed before or during the transaction.

Prepare

A prepare RPC failed after earlier steps succeeded.

Fields

step: usize

Zero-based step index that failed.

prepared: usize

Prepare steps that succeeded before the failure.

source: ClientError

Underlying client / transport error.

Commit

A commit RPC failed after earlier steps succeeded.

Fields

step: usize

Zero-based step index that failed.

committed: usize

Commit steps that succeeded before the failure.

source: ClientError

Underlying client / transport error.

Trait Implementations

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, __formatter: &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.
