Functions

func ContainAny

func ContainAny(s string, substrList []string) bool

ContainAny contain any of list

func CountPrefix

func CountPrefix(s, substr string) int

CountPrefix 和 strings.Count 类似，不过 CountPrefix 只会统计以 substr 开头的个数

当 s=**1** substr=* 的时候，返回 2 当 substr 为空的时候，一定返回 0

func FindLastAfterSubstr

func FindLastAfterSubstr(s, substr string) string

FindLastAfterSubstr 寻找字符串 s 中，匹配最后一个 substr 后的字符串

当 substr 为空的时候，必定返回空字符串 当 s==1/2/3 substr=/ 返回 3

func TeeWriter

func TeeWriter(writers []io.Writer, opt *TeeWriterOption) io.Writer

TeeWriter write data to multi writer

Types

type TeeWriterOption

type TeeWriterOption struct {
	// When an error occurs when writing data in multiple writers, exit immediately,
	// instead of writing all the writers,
	// the default is false
	// 当在多个 writer 中写数据发生错误的时候，立刻退出，而不是将所有 writer 都写完，默认是 false
	BreakWhenErr bool `json:"break_when_err"`
}
