func (*VoteTally) Affirmations 

func (tally *VoteTally) Affirmations() (c int)

Affirmations counts the number of selected ticket holders who have voted in favor of the block for the given hash.

func (*VoteTally) Mark 

func (tally *VoteTally) Mark(vote bool)

Mark adds the vote to the VoteTally.

func (*VoteTally) Status 

func (tally *VoteTally) Status() ([]int, int)

Status is a list of ints representing votes both received and not yet received for a block, and a single int representing consensus. 0: rejected, 1: affirmed, 2: vote not yet received

func (*VoteTally) VoteCount

type VotingInfo 

type VotingInfo struct {
	TicketsVoted     uint16          `json:"tickets_voted"`
	MaxVotesPerBlock uint16          `json:"max_votes_per_block"`
	VotedTickets     map[string]bool `json:"-"`
	// VoteTallys maps block hash to vote counts.
	VoteTallys map[string]*VoteTally `json:"vote_tally"`
}

VotingInfo models data about the validity of the next block from mempool.

func NewVotingInfo 

func NewVotingInfo(votesPerBlock uint16) VotingInfo

NewVotingInfo initializes a VotingInfo.

func (*VotingInfo) BlockStatus 

func (vi *VotingInfo) BlockStatus(hash string) ([]int, int)

BlockStatus fetches a list of votes in mempool, for the provided block hash. If not found, a list of VoteMissing is returned.

func (*VotingInfo) Tally 

func (vi *VotingInfo) Tally(vinfo *VoteInfo)

Tally adds the VoteInfo to the VotingInfo.VoteTally
