Functions

func BinaryToIPString

func BinaryToIPString(b []byte) string

func Compare

func Compare[T constraints.Ordered](x, y T) int

Compare returns

-1 if x is less than y,
 0 if x equals y,
+1 if x is greater than y.

For floating-point types, a NaN is considered less than any non-NaN, a NaN is considered equal to a NaN, and -0.0 is equal to 0.0.

func GenerateRandomString

func GenerateRandomString(n int) (string, error)

func GetIPFromHeader

func GetIPFromHeader(headerValue string) (string, error)

func GjsonGet

func GjsonGet(json []byte, path string) (gjson.Result, error)

func GjsonParseStringMap

func GjsonParseStringMap(jsonObject string) (map[string]string, error)

func IPDesensitize

func IPDesensitize(ipAddr string) string

func IPStringToBinary

func IPStringToBinary(ip string) ([]byte, error)

func IfOr

func IfOr[T any](a bool, x, y T) T

func IfOrFn

func IfOrFn[T any](a bool, x, y func() T) T

func IsFileExists

func IsFileExists(path string) bool

func Itoa

func Itoa[T constraints.Integer](i T) string

func SplitIPAddr

func SplitIPAddr(v4v6Bundle string) (string, string, string)

SplitIPAddr 传入/分割的v4v6混合地址，返回v4和v6地址与有效地址

func Uint64SubInt64
