Struct diem_sdk::types::epoch_state::EpochState

pub struct EpochState {
    pub epoch: u64,
    pub verifier: ValidatorVerifier,
}

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

Fields

epoch: u64

verifier: ValidatorVerifier

Implementations

impl EpochState

pub fn empty() -> EpochState

Trait Implementations

impl Clone for EpochState

pub 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

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

Formats the value using the given formatter.

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

pub fn deserialize<__D>(
    __deserializer: __D
) -> Result<EpochState, <__D as Deserializer<'de>>::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Display for EpochState

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

Formats the value using the given formatter.

impl PartialEq<EpochState> for EpochState

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

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

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

This method tests for !=.

impl Serialize for EpochState

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

Serialize this value into the given Serde serializer.

impl Verifier for EpochState

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

Verify if the ledger_info is trust worthy.

pub 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.

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

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