Types

type Decoder

type Decoder interface {
	// Decode will return io.EOF when no more objects are available.
	Decode(defaults *schema.GroupVersionKind, into runtime.Object) (runtime.Object, *schema.GroupVersionKind, error)
	// Close closes the underlying stream.
	Close() error
}

Decoder is a runtime.Decoder from a stream.

func NewDecoder

func NewDecoder(r io.ReadCloser, d runtime.Decoder) Decoder

NewDecoder creates a streaming decoder that reads object chunks from r and decodes them with d. The reader is expected to return ErrShortRead if the provided buffer is not large enough to read an entire object.

type Encoder

type Encoder interface {
	// Encode will write the provided object to the stream or return an error. It obeys the same
	// contract as runtime.VersionedEncoder.
	Encode(obj runtime.Object) error
}

Encoder is a runtime.Encoder on a stream.

func NewEncoder

func NewEncoder(w io.Writer, e runtime.Encoder) Encoder

NewEncoder returns a new streaming encoder.

type Serializer

type Serializer interface {
	NewEncoder(w io.Writer) Encoder
	NewDecoder(r io.ReadCloser) Decoder
}

Serializer is a factory for creating encoders and decoders that work over streams.
