Functions

func DecodeOrderPreservingVarUint64

func DecodeOrderPreservingVarUint64(bytes []byte) (uint64, int)

DecodeOrderPreservingVarUint64 decodes the number from the bytes obtained from method 'EncodeOrderPreservingVarUint64'. Also, returns the number of bytes that are consumed in the process

func EncodeOrderPreservingVarUint64

func EncodeOrderPreservingVarUint64(number uint64) []byte

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-comparision, first byte contains the number of remaining bytes. The presence of first byte also allows to use the returned bytes as part of other larger byte array such as a composite-key representation in db

func IsNil

func IsNil(b []byte) bool

IsNil returns true if b is either nil or zero-length array

func NotNil

func NotNil(b []byte) bool

NotNil returns true if b is a non-zero length array
