Functions

func Clone

func Clone(b []byte) []byte

Clone returns a copy of b[:len(b)]. The result may have additional unused capacity. Clone(nil) returns nil.

func Equal

func Equal(a, b []byte) bool

Equal reports whether a and b are the same length and contain the same bytes. A nil argument is equivalent to an empty slice.

func GetChangelogPath

func GetChangelogPath(dbPath string) string

func GetMemIavlDBPath

func GetMemIavlDBPath(homePath string) string

func IndexToVersion

func IndexToVersion(index uint64, initialVersion uint32) int64

IndexToVersion converts rlog index to version, reverse of versionToIndex

func Join

func Join(errs ...error) error

Join returns an error that wraps the given errors. Any nil error values are discarded. Join returns nil if errs contains no non-nil values. The error formats as the concatenation of the strings obtained by calling the Error method of each element of errs, with a newline between each string.

func NextVersion

func NextVersion(v int64, initialVersion uint32) int64

NextVersion get the next version

func VersionToIndex

func VersionToIndex(version int64, initialVersion uint32) uint64

VersionToIndex converts version to rlog index based on initial version
