CreateDirIfMissing creates a dir for dirPath if not already exists.

DecodeOrderPreservingVarUint64 decodes the number from the bytes obtained from method 'EncodeOrderPreservingVarUint64'.

DirEmpty returns true if the dir at dirPath is empty.

EncodeOrderPreservingVarUint64 returns a byte-representation for a uint64 number such that all zero-bits starting bytes are trimmed in order to reduce the length of the array For preserving the order in a default bytes-comparison, first byte contains the number of remaining bytes.

FileExists checks whether the given file exists.

ListSubdirs returns the subdirectories.

NewBuffer constructs a new instance of Buffer.

Buffer provides a wrapper on top of proto.Buffer.
