Functions

func CanBaseKeyByAddr 

func CanBaseKeyByAddr(addr common.NodeAddress) []byte

func CanBaseKeyBySuffix 

func CanBaseKeyBySuffix(addr []byte) []byte

func CanMutableKeyByAddr 

func CanMutableKeyByAddr(addr common.NodeAddress) []byte

func CanMutableKeyBySuffix

func CompareDefault 

func CompareDefault(removes NeedRemoveCans, left, right *Validator) int

NOTE: Sort By Default

When sorting is done by default, it is slashed and is sorted to the end.

The priorities just like that: Slashing > ProgramVersion > Shares > BlockNumber > TxIndex

Slashing: From no to yes ProgramVersion: From big to small Shares： From big to small BlockNumber: From small to big TxIndex: From small to big

Compare Left And Right 1: Left > Right 0: Left == Right -1:Left < Right

func CompareForDel 

func CompareForDel(removes NeedRemoveCans, left, right *Validator) int

NOTE: These are sorted by priority that will be removed

When sorting is done by delete slashing, it is slashed and is sorted to the front.

The priorities just like that: Invalid > ProgramVersion > validaotorTerm > Shares > BlockNumber > TxIndex

What is the invalid ? That are DuplicateSign and lowRatio&invalid and lowVersion and withdrew&NotInEpochValidators

Invalid Status: From invalid to valid ProgramVersion: From small to big validaotorTerm: From big to small Shares： From small to big BlockNumber: From big to small TxIndex: From big to small

Compare Left And Right 1: Left > Right 0: Left == Right -1:Left < Right

func CompareForStore 

func CompareForStore(_ NeedRemoveCans, left, right *Validator) int

NOTE: Sort when doing storage

The priorities just like that: (No shares) ProgramVersion > validaotorTerm > BlockNumber > TxIndex

Compare Left And Right 1: Left > Right 0: Left == Right -1:Left < Right
