Storage iterator options.

Types

type Iterator

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

Iterator is an iterator state representation.

func NewIterator

func NewIterator(seekCh chan storage.KeyValue, prefix []byte, opts int64) *Iterator

NewIterator creates a new Iterator with given options for a given channel of store.Seek results.

func (*Iterator) Next

func (s *Iterator) Next() bool

Next advances the iterator and returns true if Value can be called at the current position.

func (*Iterator) Value

func (s *Iterator) Value() stackitem.Item

Value returns current iterators value (exact type depends on options this iterator was created with).
