func (Index) Index ¶

func (s Index) Index(key []byte) int

Index reports the index of the given key or -1 if it could not be found. Only the first len(key) bytes from the start of the 4-byte entries will be considered for the search and the first match in Index will be returned.

func (Index) Next ¶

func (s Index) Next(key []byte, x int) int

Next finds the next occurrence of key after index x, which must have been obtained from a call to Index using the same key. It returns x+1 or -1.
