Struct DoubleVotingProof 

pub struct DoubleVotingProof<Number, Id, Signature> {
    pub first: VoteMessage<Number, Id, Signature>,
    pub second: VoteMessage<Number, Id, Signature>,
}

Proof showing that an authority voted twice in the same round.

One type of misbehavior in BEEFY happens when an authority votes in the same round/block for different payloads. Proving is achieved by collecting the signed commitments of conflicting votes.

Fields

first: VoteMessage<Number, Id, Signature>

The first vote in the equivocation.

second: VoteMessage<Number, Id, Signature>

The second vote in the equivocation.

Implementations

impl<Number, Id, Signature> DoubleVotingProof<Number, Id, Signature>

pub fn offender_id(&self) -> &Id

Returns the authority id of the equivocator.

pub fn round_number(&self) -> &Number

Returns the round number at which the equivocation occurred.

pub fn set_id(&self) -> ValidatorSetId

Returns the set id at which the equivocation occurred.

Trait Implementations

impl<Number: Clone, Id: Clone, Signature: Clone> Clone for DoubleVotingProof<Number, Id, Signature>

fn clone(&self) -> DoubleVotingProof<Number, Id, Signature>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

Formats the value using the given formatter.

impl<Number, Id, Signature> Decode for DoubleVotingProof<Number, Id, Signature>

where VoteMessage<Number, Id, Signature>: Decode,

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

impl<Number, Id, Signature> Encode for DoubleVotingProof<Number, Id, Signature>

where VoteMessage<Number, Id, Signature>: Encode,

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>
