Implementations

impl PosState

pub fn new( initial_seed: Vec<u8>, initial_nodes: Vec<(NodeID, u64)>, initial_committee: Vec<(AccountAddress, u64)>, genesis_pivot_decision: PivotBlockDecision, ) -> Self

pub fn new_empty() -> Self

pub fn set_skipped(&mut self, skipped: bool)

pub fn set_pivot_decision(&mut self, pivot_decision: PivotBlockDecision)

pub fn pivot_decision(&self) -> &PivotBlockDecision

pub fn target_term_seed(&self, target_term: u64) -> &Vec<u8>

pub fn epoch_state(&self) -> &EpochState

pub fn term_list(&self) -> &TermList

pub fn account_node_data( &self, account_address: AccountAddress, ) -> Option<&NodeData>

impl PosState

Read-only functions use in TransactionValidator

pub fn validate_election_simple( &self, election_tx: &ElectionPayload, ) -> Option<DiscardedVMStatus>

pub fn validate_pivot_decision_simple( &self, pivot_decision_tx: &PivotBlockDecision, ) -> Option<DiscardedVMStatus>

impl PosState

Read-only functions used in execute_block

pub fn validate_election(&self, election_tx: &ElectionPayload) -> Result<()>

pub fn validate_pivot_decision( &self, pivot_decision_tx: &PivotBlockDecision, signature: MultiConsensusSignature, ) -> Result<()>

pub fn validate_dispute(&self, dispute_payload: &DisputePayload) -> Result<()>

pub fn get_committee_at( &self, term: u64, ) -> Result<(ValidatorVerifier, Vec<u8>)>

Return (validator_set, term_seed).

pub fn next_elect_term(&self, author: &AccountAddress) -> Option<u64>

TODO(lpl): Return VDF seed for the term. Return Some(target_term) if author should send its election transaction.

pub fn final_serving_view(&self, author: &AccountAddress) -> Option<Round>

pub fn get_unlock_events(&self) -> Vec<ContractEvent>

pub fn current_view(&self) -> u64

pub fn skipped(&self) -> bool

pub fn next_evicted_term(&mut self) -> BTreeMap<H256, u64>

impl PosState

Write functions used apply changes (process events in PoS and PoW)

pub fn register_node(&mut self, node_id: NodeID) -> Result<()>

pub fn update_voting_power( &mut self, addr: &AccountAddress, increased_voting_power: u64, ) -> Result<()>

pub fn new_node_elected(&mut self, event: &ElectionEvent) -> Result<()>

pub fn next_view(&mut self) -> Result<Option<EpochState>>

get_new_committee has been called before this to produce an EpochState. And next_view will not be called for blocks following a pending reconfiguration block.

pub fn retire_node(&mut self, addr: &AccountAddress, votes: u64) -> Result<()>

pub fn force_retire_node(&mut self, addr: &AccountAddress) -> Result<()>

pub fn forfeit_node(&mut self, addr: &AccountAddress) -> Result<()>

impl PosState

pub fn record_update_views( &mut self, address: &AccountAddress, views: Vec<View>, )

Trait Implementations

impl Clone for PosState

fn clone(&self) -> PosState

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PosState

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PosState

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PosState

fn eq(&self, other: &PosState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for PosState

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
