Types

type Value

type Value struct {
	Key   uint8
	Value string
}

Value represents a key/value pair for META.

func (*Value) Parse

func (v *Value) Parse(s string) error

Parse k=v expression.

func (Value) String

func (v Value) String() string

type Values

type Values []Value

Values is a collection of Value.

func DecodeValues

func DecodeValues(s string) (Values, error)

DecodeValues parses a string representation of Values for the environment variable.

See Encode for the details of the encoding.

func (Values) Encode

func (v Values) Encode(allowGzip bool) string

Encode returns a string representation of Values for the environment variable.

Each Value is encoded a k=v, split by ';' character. The result is base64 encoded.
