Types

type ChecksumMapper 

type ChecksumMapper interface {
	// Get finds a checksum for a given eTag, returns false if not found
	Get(eTag string) (string, bool)
	// Set stores an eTag checksum couple if it does not already exists
	Set(eTag, checksum string)
	// Purge removes unknown values based on the full list of know values
	Purge(knownETags []string) int
}

ChecksumMapper maintains a mapping of eTags => checksum

type Client 

type Client struct {
	Oc                          nodes.StorageClient
	Bucket                      string
	RootPath                    string
	Host                        string
	ServerRequiresNormalization bool
	// contains filtered or unexported fields
}

Client wraps a Minio Client to speak with an S3-compatible backend
