func (e ChecksumError) Error() string

type Decoder

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

Decoder provides decoding of an Event Stream messages.

func NewDecoder

func NewDecoder(r io.Reader, opts ...func(*Decoder)) *Decoder

NewDecoder initializes and returns a Decoder for decoding event stream messages from the reader provided.

func (*Decoder) Decode

func (d *Decoder) Decode(payloadBuf []byte) (m Message, err error)

func (Headers) Get

func (hs Headers) Get(name string) Value

Get returns the Value associated with the header. Nil is returned if the value does not exist.

func (*Headers) Set

func (hs *Headers) Set(name string, value Value)

Set associates the name with a value. If the header name already exists in the Headers the value will be replaced with the new one.
