type Reverter ¶
type Reverter struct {

Reverter provides functionality to automatically revert a set of executed operations. It can be used this way:
r := reverter.New() defer r.Finish()
doOperation()
r.Add(func() error {
revertOperation()
return nil
})
if err := doOtherOperation(); err != nil {
return err
}
r.Defuse()
func (*Reverter) Add ¶
func (r *Reverter) Add(f ...RevertFunc)
Add adds a new revert function to the reverter which will be called when Finish() is called unless the reverter gets defused.
