pub struct AnsiTransactionManager { /* private fields */ }
Expand description

An implementation of TransactionManager which can be used for backends which use ANSI standard syntax for savepoints such as SQLite and PostgreSQL.

Implementations

Begin a transaction with custom SQL

This is used by connections to implement more complex transaction APIs to set things such as isolation levels. Returns an error if already inside of a transaction.

Returns the “default value” for a type. Read more

If the transaction fails to commit due to a SerializationFailure or a ReadOnlyTransaction a rollback will be attempted. If the rollback succeeds, the original error will be returned, otherwise the error generated by the rollback will be returned. In the second case the connection will be considered broken as it contains a uncommitted unabortable open transaction.
