Functions

func CreateMultihash

func CreateMultihash(bytes []byte) ([]byte, error)

CreateMultihash creates a multihash given bytes

func IntOrEmptyInt

func IntOrEmptyInt(s *int) int

IntOrEmptyInt returns an empty int if a int pointer is nil. Otherwise returns the int value of the pointer.

func IntToPtr

func IntToPtr(s int) *int

IntToPtr is a convenience func that converts a int to it's pointer

func MultiHashString

func MultiHashString(str string) (string, error)

MultiHashString create a multihash hex from a string

func StrOrEmptyStr

func StrOrEmptyStr(s *string) string

StrOrEmptyStr returns an empty string if a string pointer is nil. Otherwise returns the string value of the pointer.

func StrToPtr

func StrToPtr(s string) *string

StrToPtr is a convenience func that converts a string to it's pointer
