Functions

func HasProposedForEpoch added in v0.3.2

func HasProposedForEpoch(history *slashpb.ProposalHistory, epoch uint64) bool

HasProposedForEpoch returns whether a validators proposal history has been marked for the entered epoch. If the request is more in the future than what the history contains, it will return false. If the request is from the past, and likely previously pruned it will return false.

func SetProposedForEpoch added in v0.3.2

func SetProposedForEpoch(history *slashpb.ProposalHistory, epoch uint64) *slashpb.ProposalHistory

SetProposedForEpoch updates the proposal history to mark the indicated epoch in the bitlist and updates the last epoch written if needed. Returns the modified proposal history.

type Validator

type Validator interface {
	Done()
	WaitForChainStart(ctx context.Context) error
