Struct ValidatorSet 

pub struct ValidatorSet { /* private fields */ }

Implementations

impl ValidatorSet

pub fn new(validators: Vec<ValidatorInfo>) -> Self

pub fn from_signers(signers: &[&dyn Signer]) -> Self

Build a ValidatorSet from signers with equal power (1 each).

pub fn rebuild_index(&mut self)

Rebuild the index map after deserialization.

NOTE: This is now called automatically during deserialization. You only need to call this manually if you modify the validators list directly.

pub fn validators(&self) -> &[ValidatorInfo]

pub fn total_power(&self) -> u64

pub fn quorum_threshold(&self) -> u64

Quorum threshold: ceil(2n/3) where n = total_power

pub fn max_faulty_power(&self) -> u64

Maximum faulty power: total_power - quorum_threshold

pub fn leader_for_view(&self, view: ViewNumber) -> &ValidatorInfo

Round-robin leader selection: v mod n

pub fn validator_count(&self) -> usize

pub fn index_of(&self, id: ValidatorId) -> Option<usize>

O(1) index lookup

pub fn get(&self, id: ValidatorId) -> Option<&ValidatorInfo>

O(1) validator info lookup

pub fn power_of(&self, id: ValidatorId) -> u64

pub fn apply_updates(&self, updates: &[ValidatorUpdate]) -> ValidatorSet

Apply validator updates and return a new ValidatorSet.

• power > 0: update existing validator’s power/key, or add new validator
• power == 0: remove validator

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
