Struct diem_types::epoch_state::EpochState

pub struct EpochState {
    pub epoch: u64,
    pub vrf_seed: Vec<u8>,
    /* private fields */
}

EpochState represents a trusted validator set to validate messages from the specific epoch, it could be updated with EpochChangeProof.

Fields

epoch: u64

vrf_seed: Vec<u8>

Implementations

impl EpochState

pub fn empty() -> Self

pub fn new(epoch: u64, verifier: ValidatorVerifier, vrf_seed: Vec<u8>) -> Self

pub fn verifier(&self) -> &ValidatorVerifier

Trait Implementations

impl Clone for EpochState

fn clone(&self) -> EpochState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EpochState

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EpochState

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for EpochState

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

Formats the value using the given formatter.

impl OnChainConfig for EpochState

const IDENTIFIER: &'static str = "DiemSystem"

const ADDRESS: &'static str = CONFIG_ADDRESS_STR

const CONFIG_ID: ConfigID = _

fn deserialize_default_impl(bytes: &[u8]) -> Result<Self>

fn deserialize_into_config(bytes: &[u8]) -> Result<Self>

fn fetch_config<T>(storage: &T) -> Option<Self>

where T: ConfigStorage,

impl PartialEq for EpochState

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for EpochState

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Verifier for EpochState

fn verify(&self, ledger_info: &LedgerInfoWithSignatures) -> Result<()>

Verify if the ledger_info is trust worthy.

fn epoch_change_verification_required(&self, epoch: u64) -> bool

Returns true in case the given epoch is larger than the existing verifier can support. In this case the EpochChangeProof should be verified and the verifier updated.

fn is_ledger_info_stale(&self, ledger_info: &LedgerInfo) -> bool

Returns true if the given LedgerInfo is stale and probably in our trusted prefix.
