func HandleTX(complete bool, atomic *Atomic, err error) error

HandleTX completes the given transaction if an error is supplied a rollback is performed

type Atomic struct {
	*sqlx.Tx
	Active bool
}

Atomic defines a transactional operation - like the A in ACID https://en.wikipedia.org/wiki/ACID

func CheckTX(c Connection, a *Atomic) (*Atomic, error)

CheckTX returns a new Atomic object if the supplied object is inactive if the supplied object is active - the same object is returned

type Connection struct {
	*sqlx.DB
	Active bool
}

Connection defines a storage/database/... connection

func NewConn(connstr string) Connection

NewConn creates a connection to a store/repository

func NewFromDB(db *sqlx.DB) Connection

NewFromDB creates a new connection based on existing DB handle

func (c Connection) CreateAtomic() (Atomic, error)

CreateAtomic starts a new transaction
