Types

type CallbackIterator

type CallbackIterator struct {
	// contains filtered or unexported fields
}

func NewCallbackIterator

func NewCallbackIterator(next func() bool, value func() (string, error), close func() error) *CallbackIterator

NewCallbackIterator provides an iterator interface based on closure callbacks

func (*CallbackIterator) Close

func (i *CallbackIterator) Close() error

Close performs any cleanups. It may be used to return the last error

func (*CallbackIterator) Next

func (i *CallbackIterator) Next() bool

Next returns true if we have more iterations pending

func (*CallbackIterator) Value

func (i *CallbackIterator) Value() (string, error)
