type RemoteIterator

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

func (*RemoteIterator) Error

func (i *RemoteIterator) Error() error

Error returns any accumulated error. Exhausting all the key/value pairs is not considered to be an error.

func (*RemoteIterator) Key

func (i *RemoteIterator) Key() []byte

Key returns the key of the current key/value pair, or nil if done. The caller should not modify the contents of the returned slice, and its contents may change on the next call to Next.

func (*RemoteIterator) Next

func (i *RemoteIterator) Next() bool

Next moves the iterator to the next key/value pair. It returns whether the iterator is exhausted.

func (*RemoteIterator) Release

func (i *RemoteIterator) Release()

Release releases associated resources. Release should always succeed and can be called multiple times without causing error.

func (*RemoteIterator) Value

func (i *RemoteIterator) Value() []byte

Value returns the value of the current key/value pair, or nil if done. The caller should not modify the contents of the returned slice, and its contents may change on the next call to Next.
