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 Arbitrary for EpochState

type Parameters = (<u64 as Arbitrary>::Parameters, <ValidatorVerifier as Arbitrary>::Parameters)

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Map<(<u64 as Arbitrary>::Strategy, <ValidatorVerifier as Arbitrary>::Strategy), fn(_: (u64, ValidatorVerifier)) -> EpochState>

The type of Strategy used to generate values of type Self.

fn arbitrary_with( _top: <EpochState as Arbitrary>::Parameters ) -> <EpochState as Arbitrary>::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

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<(), Error>

Formats the value using the given formatter.

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

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

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

Formats the value using the given formatter.

impl PartialEq<EpochState> 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 as Serializer>::Ok, <__S as Serializer>::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Verifier for EpochState

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

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.
