Types

type Encoding

type Encoding struct {
	// contains filtered or unexported fields
}

Encoding represents a given base-N encoding.

func NewEncoding

func NewEncoding(alphabet string) *Encoding

NewEncoding creates a new base-N representation from the given alphabet. Panics if the alphabet is not unique. Only ASCII characters are supported.

func (*Encoding) Base

func (enc *Encoding) Base() int

Base returns the number base of the encoding.

func (*Encoding) DecodeString

func (enc *Encoding) DecodeString(s string) ([]byte, error)

DecodeString returns the bytes for the given base-encoded string.

func (*Encoding) DecodeStringN

func (enc *Encoding) DecodeStringN(s string, n int) ([]byte, error)

DecodeStringN returns N bytes for the given base-encoded string. Use this method to ensure the value is left-padded with zeroes.

func (*Encoding) EncodeToString

func (enc *Encoding) EncodeToString(b []byte) string

EncodeToString returns the base-encoded string representation of the given bytes.

func (*Encoding) MustRandom

func (enc *Encoding) MustRandom(n int) string

MustRandom returns the base-encoded representation of n random bytes, panicking in the unlikely event of a read error from the random source.

func (*Encoding) Random

func (enc *Encoding) Random(n int) (string, error)

Random returns the base-encoded representation of n random bytes.
