Functions

func B2S

func B2S(b []byte) string

b2s converts byte slice to a string without memory allocation. See https://groups.google.com/forum/#!msg/Golang-Nuts/ENgbUzYvCuU/90yGx7GUAgAJ .

Note it may break if string and/or slice header will change in the future go versions.

func GenerateRandomBytes

func GenerateRandomBytes(n int) ([]byte, error)

GenerateRandomBytes returns securely generated random bytes. It will return an error if the system's secure random number generator fails to function correctly, in which case the caller should not continue.

func GenerateRandomString

func GenerateRandomString(s int) (string, error)

GenerateRandomString returns a URL-safe

func Int64Pointer

func Int64Pointer(i int64) *int64

func IsPowerOfTwo

func IsPowerOfTwo(n int64) bool

Util - Is Power Of Two

func OrPanic

func OrPanic(args ...interface{}) []interface{}

func S2B

func S2B(s string) (b []byte)

S2B converts string to a byte slice without memory allocation.

Note it may break if string and/or slice header will change in the future go versions. Warning: Writing data into the array is not a good idea, as this will result in a segfault This is really bad do not writing or modity the data in the array which is returned.

func StringPointer

func StringPointer(s string) *string

func TlsConfig

func TlsConfig(pubkey string) *tls.Config
