Functions

func Decode

func Decode(input []byte) ([]byte, error)

Decode decodes a byte array to provide an interface like `base64/DecodeString`.

func DecodeGunzip

func DecodeGunzip(encoded string) ([]byte, error)

DecodeGunzip base64 decodes a string with optional gzip uncompression.

func DecodeGunzipJSON

func DecodeGunzipJSON(encoded string, output any) error

DecodeGunzipJSON base64 decodes a string with optoinal gunzip uncompression and then unmarshals the data to a struct.

func EncodeGzip

func EncodeGzip(data []byte, compressLevel int) (string, error)

Encode with optional gzip compression. 0 = no compression. 9 = best compression.

func EncodeGzipJSON

func EncodeGzipJSON(data any, compressLevel int) (string, error)

EncodeGzipJSON encodes a struct that is JSON encoded.

func IsValid

func IsValid(input []byte) bool

func IsValidString

func IsValidString(input string) bool

func Pad

func Pad(encoded string) string

func ReadAll

func ReadAll(r io.Reader) ([]byte, error)

ReadAll provides an interface like `io.ReadAll` with optional base64 decoding. It is useful for decoding `*http.Response.Body`.

func StripPadding

func StripPadding(str string) string
