Struct TransactionCommitError 

pub struct TransactionCommitError { /* private fields */ }

A failed to commit transaction.

Implementations

impl TransactionCommitError

pub fn on_error(self) -> impl Future<Output = FdbResult<Transaction>>

Implements the recommended retry and backoff behavior for a transaction. This function knows which of the error codes generated by other Transaction functions represent temporary error conditions and which represent application errors that should be handled by the application. It also implements an exponential backoff strategy to avoid swamping the database cluster with excessive retries when there is a high level of conflict between transactions.

You should not call this method most of the times and use Database::transact which implements a retry loop strategy for you.

pub async fn conflicting_keys(&self) -> FdbResult<Vec<ConflictingKeyRange>>

Reads the conflicting key ranges that caused this commit failure.

Only returns meaningful results if TransactionOption::ReportConflictingKeys was set on the transaction and the error is not_committed (code 1020).

Must be called before on_error which resets the transaction.

Errors

Returns an FdbError if the special keyspace read fails.

pub fn reset(self) -> Transaction

Reset the transaction to its initial state.

This is similar to dropping the transaction and creating a new one.

Trait Implementations

impl Debug for TransactionCommitError

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

Formats the value using the given formatter.

impl Deref for TransactionCommitError

type Target = FdbError

The resulting type after dereferencing.

fn deref(&self) -> &FdbError

Dereferences the value.

impl Display for TransactionCommitError

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

Formats the value using the given formatter.

impl Error for TransactionCommitError

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 From<TransactionCommitError> for FdbError

fn from(tce: TransactionCommitError) -> FdbError

Converts to this type from the input type.
