Functions ¶
func InitializeDecompressStreams ¶
func InitializeDecompressStreams(streams map[string]config.DecompressStream) error
InitializeDecompressStreams initializes the snapshotter's decompress stream functions.
This function is a singleton function; after the first call follow on calls will produce the same result.
Types ¶
type DecompressStream ¶
type DecompressStream func(io.Reader) (compression.DecompressReadCloser, error)
DecompressStream is any function which decompresses an archive.
It is defined to match github.com/containerd/containerd/archive/compression.DecompressStream for easier swapping of decompress stream functionality.
func GetDecompressStream ¶
func GetDecompressStream(layerMediaType string) (DecompressStream, bool)
GetDecompressStream returns the decompress stream function for a provided layer media type if the snapshotter has been configured to decompress it.
If no decompression stream is found, then return false.
