pub enum TransactionBehavior {
Deferred,
Immediate,
Exclusive,
}
Expand description
Options for transaction behavior. See BEGIN TRANSACTION for details.
Variants (Non-exhaustive)
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Deferred
DEFERRED means that the transaction does not actually start until the database is first accessed.
Immediate
IMMEDIATE cause the database connection to start a new write immediately, without waiting for a writes statement.
Exclusive
EXCLUSIVE prevents other database connections from reading the database while the transaction is underway.
