Functions

func AddressRange

func AddressRange(network *net.IPNet) (net.IP, net.IP)

AddressRange returns the first and last addresses in the given CIDR range.

func Any

func Any(arrays []string, excludes ...string) string

func Append

func Append(ips []string, app string) []string

func Assert

func Assert(check bool, msg string, params ...interface{})

func Async

func Async() *async

func Base64File

func Base64File(file string) string

func CamelName

func CamelName(name string) string

下划线写法转为驼峰写法

func Catch

func Catch(fns ...func(error))

func CompileSplit2

func CompileSplit2(str, sep string) (a, b string)

func CompileSplit3

func CompileSplit3(str, sep string) (a, b, c string)

func ComposeIP

func ComposeIP(a, b net.IP) int

func Copy

func Copy(src, dest string) (err error)

func Copyto

func HashApr1

func HashApr1(password string) (string, error)

func HashApr1WithSalt

func HashApr1WithSalt(password, salt string) (string, error)

Hash hashes the given password, along with the salt. I did not design this algorithm, only re-implement and optimize slightly. This assumes strings are valid UTF-8 encoded strings. The salt must be 8 bytes long. This algorithm is adopted from the Java implementation found here: http://commons.apache.org/proper/commons-codec/apidocs/src-html/org/apache/commons/codec/digest/Md5Crypt.html
