MongoDB\Driver\Exception\RuntimeException::hasErrorLabel

说明

Returns whether the errorLabel has been set for this exception. Error labels are set by either the server or the extension to indicate specific situations that may be handled by an application. A common situation might be determining whether to safely retry a transaction that failed due to a transient error (e.g. network error, transaction conflict). Examples of error labels are TransientTransactionError and UnknownTransactionCommitResult.
