Functions ¶

func GetDiffer ¶

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

GetDiffer returns a differ than can be used with ApplyDiffWithDiffer. If it returns an error that matches ErrFallbackToOrdinaryLayerDownload, the caller can retry the operation with a different method.

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. Deprecated: Use pkg/chunked/compressor.ZstdCompressor.

Types ¶

type ErrBadRequest ¶

type ErrBadRequest struct {
}

ErrBadRequest is returned when the request is not valid

func (ErrBadRequest) Error ¶

func (e ErrBadRequest) Error() string

type ErrFallbackToOrdinaryLayerDownload ¶

type ErrFallbackToOrdinaryLayerDownload struct {
	Err error
}

ErrFallbackToOrdinaryLayerDownload is a custom error type that suggests to the caller that a fallback mechanism can be used instead of a hard failure.

func (ErrFallbackToOrdinaryLayerDownload) Error ¶

func (c ErrFallbackToOrdinaryLayerDownload) Error() string

func (ErrFallbackToOrdinaryLayerDownload) Unwrap ¶

func (c ErrFallbackToOrdinaryLayerDownload) Unwrap() error

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.
