Types

type Validators

type Validators struct {
	// contains filtered or unexported fields
}

Validators group of an epoch with weights. Optimized for BFT algorithm calculations. Read-only.

func ArrayToValidators

func ArrayToValidators(ids []idx.ValidatorID, weights []Weight) *Validators

ArrayToValidators builds new read-only Validators object from array

func EqualWeightValidators

func EqualWeightValidators(ids []idx.ValidatorID, weight Weight) *Validators

EqualWeightValidators builds new read-only Validators object with equal weights (for tests)

func (*Validators) Builder

func (vv *Validators) Builder() ValidatorsBuilder

Builder returns a mutable copy of content

func (*Validators) Copy

func (vv *Validators) Copy() *Validators

Copy constructs a copy.

func (*Validators) DecodeRLP

func (vv *Validators) DecodeRLP(s *rlp.Stream) error

DecodeRLP is for RLP deserialization.

func (*Validators) EncodeRLP

func (vv *Validators) EncodeRLP(w io.Writer) error

EncodeRLP is for RLP serialization.

func (*Validators) Exists

func (vv *Validators) Exists(id idx.ValidatorID) bool

Exists returns boolean true if address exists in Validators object

func (*Validators) Get

func (vv *Validators) Get(id idx.ValidatorID) Weight

get returns weight for validator by ID

func (*Validators) GetID

func (vv *Validators) GetID(i idx.Validator) idx.ValidatorID

GetID returns index validator ID by index (offset) of validator in the group

func (*Validators) GetIdx

func (vv *Validators) GetIdx(id idx.ValidatorID) idx.Validator

GetIdx returns index (offset) of validator in the group

func (*Validators) GetWeightByIdx

func (vv *Validators) GetWeightByIdx(i idx.Validator) Weight

GetWeightByIdx returns weight for validator by index

func (*Validators) IDs

func (vv *Validators) IDs() []idx.ValidatorID

IDs returns not sorted ids.

func (*Validators) Idxs

func (vv *Validators) Idxs() map[idx.ValidatorID]idx.Validator

Idxs gets deterministic total order of validators.

func (*Validators) Len

func (vv *Validators) Len() idx.Validator

Len returns count of validators in Validators objects

func (Validators) NewCounter

func (vv Validators) NewCounter() *WeightCounter

NewCounter constructor.

func (*Validators) Quorum

func (vv *Validators) Quorum() Weight

Quorum limit of validators.

func (*Validators) SortedIDs

func (vv *Validators) SortedIDs() []idx.ValidatorID

SortedIDs returns deterministically sorted ids. The order is the same as for Idxs().

func (*Validators) SortedWeights

func (vv *Validators) SortedWeights() []Weight

SortedWeights returns deterministically sorted weights. The order is the same as for Idxs().

func (*Validators) TotalWeight

func (vv *Validators) TotalWeight() (sum Weight)

TotalWeight of validators.
