Enum polkadot_statement_table::generic::Statement

pub enum Statement<Candidate, Digest> {
    Seconded(Candidate),
    Valid(Digest),
}

Statements circulated among peers.

Variants

Seconded(Candidate)

Broadcast by an authority to indicate that this is its candidate for inclusion.

Broadcasting two different candidate messages per round is not allowed.

Valid(Digest)

Broadcast by a authority to attest that the candidate with given digest is valid.

Trait Implementations

impl<Candidate: Clone, Digest: Clone> Clone for Statement<Candidate, Digest>

fn clone(&self) -> Statement<Candidate, Digest>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Candidate: Debug, Digest: Debug> Debug for Statement<Candidate, Digest>

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

Formats the value using the given formatter.

impl<Candidate, Digest> Decode for Statement<Candidate, Digest>where Candidate: Decode, Digest: Decode,

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

Attempt to deserialise the value from input.

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<Candidate, Digest> Encode for Statement<Candidate, Digest>where Candidate: Encode, Digest: Encode,

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

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

fn size_hint(&self) -> usize

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

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

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere 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<'a> From<&'a Statement<CommittedCandidateReceipt<H256>, CandidateHash>> for PrimitiveStatement

fn from(s: &'a Statement) -> PrimitiveStatement

Converts to this type from the input type.

impl<Candidate: PartialEq, Digest: PartialEq> PartialEq<Statement<Candidate, Digest>> for Statement<Candidate, Digest>

fn eq(&self, other: &Statement<Candidate, Digest>) -> 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.
