Enum polkadot_primitives::v8::DisputeStatement

pub enum DisputeStatement {
    Valid(ValidDisputeStatementKind),
    Invalid(InvalidDisputeStatementKind),
}

A statement about a candidate, to be used within the dispute resolution process.

Statements are either in favor of the candidate’s validity or against it.

Variants

Valid(ValidDisputeStatementKind)

A valid statement, of the given kind.

Invalid(InvalidDisputeStatementKind)

An invalid statement, of the given kind.

Implementations

impl DisputeStatement

pub fn payload_data( &self, candidate_hash: CandidateHash, session: SessionIndex, ) -> Result<Vec<u8>, ()>

Get the payload data for this type of dispute statement.

Returns Error if the candidate_hash is not included in the list of signed candidate from ApprovalCheckingMultipleCandidate.

pub fn check_signature( &self, validator_public: &ValidatorId, candidate_hash: CandidateHash, session: SessionIndex, validator_signature: &ValidatorSignature, ) -> Result<(), ()>

Check the signature on a dispute statement.

pub fn indicates_validity(&self) -> bool

Whether the statement indicates validity.

pub fn indicates_invalidity(&self) -> bool

Whether the statement indicates invalidity.

pub fn is_backing(&self) -> bool

Statement is backing statement.

Trait Implementations

impl Clone for DisputeStatement

fn clone(&self) -> DisputeStatement

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DisputeStatement

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

Formats the value using the given formatter.

impl Decode for DisputeStatement

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,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Encode for DisputeStatement

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>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl PartialEq for DisputeStatement

fn eq(&self, other: &DisputeStatement) -> 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 TypeInfo for DisputeStatement

type Identity = DisputeStatement

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
