## 语法
```
type Index
func New(data []byte) *Index
func (x *Index) Bytes() []byte
func (x *Index) Read(r io.Reader) error
func (x *Index) Write(w io.Writer) error
func (x *Index) Lookup(s []byte, n int) (result []int)
func (x *Index) FindAllIndex(r *regexp.Regexp, n int) (result [][]int)
```
## 示例
```
index := suffixarray.New([]byte("abc abc abc"))
offsets := index.Lookup([]byte("bc"), -1)
fmt.Printf("%+v\n", offsets) // [9 5 1]
compile := regexp.MustCompile("bc")
allIndex := index.FindAllIndex(compile, -1)
fmt.Printf("%+v\n", allIndex) // [[1 3] [5 7] [9 11]]
```
