XA errors returned from XaResource operations.

Variants

NotFound

The XID is not valid or cannot be found.

Invalid

Invalid arguments passed.

Protocol(String)

Protocol error (operation called in wrong state).

RmFail(String)

Resource manager failure.

DuplicateXid

Duplicate XID.

Outside

Work performed outside global transaction.

HeuristicCommit

Heuristic commit (TM should forget).

HeuristicRollback

Heuristic rollback (TM should forget).

CrashDurabilityNotSupported

👎Deprecated since 2.0.0:

crash-durable XA is now supported (wave 3-2); this variant is no longer returned

This variant is retained for SemVer compatibility but is no longer returned by the engine. Crash- durable XA is now supported — a TxnPrepare WAL frame is written by xa_prepare, recovery surfaces in-doubt XIDs via xa_recover(), and xa_commit / xa_rollback resolve them against the recovered prepared list maintained on the EnvironmentImpl.

New code should not match on this variant. It will be removed in v3.0.

Use XaError::NotFound for genuinely unknown XIDs and XaError::Protocol for state-machine violations.

Xid(XidError)

Xid construction error.

Db(NoxuError)

Underlying database error.

Trait Implementations
