## 主要函数如下：
~~~
func Compare(a, b string) int
是否包含子串
func Contains(s, substr string) bool
是否包含包括unicode
func ContainsAny(s, chars string) bool
func ContainsRune(s string, r rune) bool
统计sep出现的次数，如果sep为空则为len(s)+1
func Count(s, sep string) int
func EqualFold(s, t string) bool
用1个或多个空格来进行分割字符串
func Fields(s string) []string
func FieldsFunc(s string, f func(rune) bool) []string
匹配头部，零值字符串也会匹配成功
func HasPrefix(s, prefix string) bool
匹配尾部
func HasSuffix(s, suffix string) bool
查找sep在s中的索引位置，如果不存在为-1
func Index(s, sep string) int
匹配任何第一个相同的串
func IndexAny(s, chars string) int
func IndexByte(s string, c byte) int
func IndexFunc(s string, f func(rune) bool) int
func IndexRune(s string, r rune) int
合并字符串
func Join(a []string, sep string) string
返回最后一个匹配的索引位置
func LastIndex(s, sep string) int
func LastIndexAny(s, chars string) int
func LastIndexByte(s string, c byte) int
func LastIndexFunc(s string, f func(rune) bool) int
func Map(mapping func(rune) rune, s string) string
重复字符串追加几次
func Repeat(s string, count int) string
替换字符串
func Replace(s, old, new string, n int) string
分割字符串
func Split(s, sep string) []string
func SplitAfter(s, sep string) []string
分割成几个
func SplitAfterN(s, sep string, n int) []string
func SplitN(s, sep string, n int) []string
英文里面首字母大写
func Title(s string) string
转换小写
func ToLower(s string) string
func ToLowerSpecial(c unicode.SpecialCase, s string) string
func ToTitle(s string) string
func ToTitleSpecial(c unicode.SpecialCase, s string) string
转换成大写
func ToUpper(s string) string
func ToUpperSpecial(c unicode.SpecialCase, s string) string
前后空白字符删除 strip

func TrimFunc(s string, f func(rune) bool) string
清除左侧空白字符
func TrimLeft(s string, cutset string) string
func TrimLeftFunc(s string, f func(rune) bool) string
清除前缀，类剪切只是匹配前缀
func TrimPrefix(s, prefix string) string
func TrimRight(s string, cutset string) string
func TrimRightFunc(s string, f func(rune) bool) string
清除前后的空白字符
func TrimSpace(s string) string
从后匹配进行清除
func TrimSuffix(s, suffix string) string
