Functions

func GetDiffer

func GetDiffer(ctx context.Context, store storage.Store, blobSize int64, annotations map[string]string, iss ImageSourceSeekable) (graphdriver.Differ, error)

GetDiffer returns a differ than can be used with ApplyDiffWithDiffer.

func ZstdCompressor

func ZstdCompressor(r io.Writer, metadata map[string]string, level *int) (io.WriteCloser, error)

ZstdCompressor is a CompressorFunc for the zstd compression algorithm.

Types

type ErrBadRequest

type ErrBadRequest struct {
}

ErrBadRequest is returned when the request is not valid

func (ErrBadRequest) Error

func (e ErrBadRequest) Error() string

type ImageSourceChunk

type ImageSourceChunk struct {
	Offset uint64
	Length uint64
}

ImageSourceChunk is a portion of a blob.

type ImageSourceSeekable

type ImageSourceSeekable interface {
	// GetBlobAt returns a stream for the specified blob.
	GetBlobAt([]ImageSourceChunk) (chan io.ReadCloser, chan error, error)
}

ImageSourceSeekable is an image source that permits to fetch chunks of the entire blob.
