Struct txDriver

entc/integration/ent/tx.go:222–231

txDriver wraps the given dialect.Tx with a nop dialect.Driver implementation. The idea is to support transactions without adding any extra code to the builders. When a builder calls to driver.Tx(), it gets the same dialect.Tx instance. Commit and Rollback are nop for the internal builders and the us

//
// Note that txDriver is not goroutine safe.
type txDriver struct {
	// the driver we started the transaction from.
	drv dialect.Driver
	// tx is the underlying transaction.
	tx dialect.Tx
	// completion hooks.
	mu         sync.Mutex
	onCommit   []CommitHook
	onRollback []RollbackHook
}

// newTx creates a new transactional driver.
