Struct diem_sdk::types::epoch_change::EpochChangeProof

pub struct EpochChangeProof {
    pub ledger_info_with_sigs: Vec<LedgerInfoWithSignatures, Global>,
    pub more: bool,
}

A vector of LedgerInfo with contiguous increasing epoch numbers to prove a sequence of epoch changes from the first LedgerInfo’s epoch.

Fields

ledger_info_with_sigs: Vec<LedgerInfoWithSignatures, Global>

more: bool

Implementations

impl EpochChangeProof

pub fn new( ledger_info_with_sigs: Vec<LedgerInfoWithSignatures, Global>, more: bool ) -> EpochChangeProof

pub fn epoch(&self) -> Result<u64, Error>

The first/lowest epoch of the proof to indicate which epoch this proof is helping with

pub fn verify( &self, verifier: &dyn Verifier ) -> Result<&LedgerInfoWithSignatures, Error>

Verify the proof is correctly chained with known epoch and validator verifier and return the LedgerInfoWithSignatures to start target epoch.

In case a waypoint is present, it’s going to be used for verifying the very first epoch change (it’s the responsibility of the caller to not pass a waypoint in case it’s not needed).

We will also skip any stale ledger info’s in the EpochChangeProof.

Trait Implementations

impl Arbitrary for EpochChangeProof

type Parameters = ()

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

type Strategy = BoxedStrategy<EpochChangeProof>

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

fn arbitrary_with( _args: <EpochChangeProof as Arbitrary>::Parameters ) -> <EpochChangeProof 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 EpochChangeProof

fn clone(&self) -> EpochChangeProof

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EpochChangeProof

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EpochChangeProof

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

Deserialize this value from the given Serde deserializer.

impl PartialEq<EpochChangeProof> for EpochChangeProof

fn eq(&self, other: &EpochChangeProof) -> 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 EpochChangeProof

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.
