type ValidatorCurrentRewardsRecord struct {
	ValidatorAddress sdk.ValAddress          `json:"validator_address" yaml:"validator_address"`

used for import / export via genesis json

type ValidatorHistoricalRewards 

type ValidatorHistoricalRewards struct {

	ReferenceCount        uint16       `json:"reference_count" yaml:"reference_count"`
}

historical rewards for a validator height is implicit within the store key cumulative reward ratio is the sum from the zeroeth period until this period of rewards / tokens, per the spec The reference count indicates the number of objects which might need to reference this historical entry at any point. ReferenceCount = 

  number of outstanding delegations which ended the associated period (and might need to read that record)
+ number of slashes which ended the associated period (and might need to read that record)
+ one per validator for the zeroeth period, set on initialization

func NewValidatorHistoricalRewards 

func NewValidatorHistoricalRewards(cumulativeRewardRatio sdk.DecCoins, referenceCount uint16) ValidatorHistoricalRewards

create a new ValidatorHistoricalRewards

type ValidatorHistoricalRewardsRecord struct {

used for import / export via genesis json

type ValidatorOutstandingRewards 

type ValidatorOutstandingRewards = sdk.DecCoins

outstanding (un-withdrawn) rewards for a validator inexpensive to track, allows simple sanity checks

type ValidatorOutstandingRewardsRecord 

type ValidatorOutstandingRewardsRecord struct {
	ValidatorAddress   sdk.ValAddress `json:"validator_address" yaml:"validator_address"`
	OutstandingRewards sdk.DecCoins   `json:"outstanding_rewards" yaml:"outstanding_rewards"`
}

type ValidatorSlashEvent 

type ValidatorSlashEvent struct {

	Fraction        sdk.Dec `json:"fraction" yaml:"fraction"`                 // slash fraction
}

validator slash event height is implicit within the store key needed to calculate appropriate amounts of staking token for delegations which withdraw after a slash has occurred
