Type Alias polkadot_statement_table::v2::Statement

pub type Statement = Statement<CommittedCandidateReceipt, CandidateHash>;

Statements about candidates on the network.

Aliased Type

enum Statement {
    Seconded(CommittedCandidateReceipt),
    Valid(CandidateHash),
}

Variants

Seconded(CommittedCandidateReceipt)

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

Broadcasting two different candidate messages per round is not allowed.

Valid(CandidateHash)

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

where Candidate: Encode, Digest: 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>

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<Candidate: PartialEq, Digest: PartialEq> PartialEq 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.
