func (Key) Cmp ¶

func (k Key) Cmp(another Key) int

Cmp returns the comparison result of two keys. The result will be 0 if a==b, -1 if a < b, and +1 if a > b.

func (Key) HasPrefix ¶

func (k Key) HasPrefix(prefix Key) bool

HasPrefix tests whether the Key begins with prefix.

func (Key) Next ¶

func (k Key) Next() Key

Next returns the next key in byte-order.

func (Key) PrefixNext ¶

func (k Key) PrefixNext() Key

PrefixNext returns the next prefix key.

Assume there are keys like:

rowkey1
rowkey1_column1
rowkey1_column2
rowKey2

If we seek 'rowkey1' Next, we will get 'rowkey1_column1'. If we seek 'rowkey1' PrefixNext, we will get 'rowkey2'.
