Enum polkadot_node_network_protocol::vstaging::StatementDistributionMessage

pub enum StatementDistributionMessage {
    Statement(Hash, UncheckedSignedStatement),
    BackedCandidateManifest(BackedCandidateManifest),
    BackedCandidateKnown(BackedCandidateAcknowledgement),
    V1Compatibility(StatementDistributionMessage),
}

Network messages used by the statement distribution subsystem.

Variants

Statement(Hash, UncheckedSignedStatement)

A notification of a signed statement in compact form, for a given relay parent.

BackedCandidateManifest(BackedCandidateManifest)

A notification of a backed candidate being known by the sending node, for the purpose of being requested by the receiving node if needed.

BackedCandidateKnown(BackedCandidateAcknowledgement)

A notification of a backed candidate being known by the sending node, for the purpose of informing a receiving node which already has the candidate.

V1Compatibility(StatementDistributionMessage)

All messages for V1 for compatibility with the statement distribution protocol, for relay-parents that don’t support asynchronous backing.

These are illegal to send to V1 peers, and illegal to send concerning relay-parents which support asynchronous backing. This backwards compatibility should be considered immediately deprecated and can be removed once the node software is not required to support logic from before asynchronous backing anymore.

Trait Implementations

impl Clone for StatementDistributionMessage

fn clone(&self) -> StatementDistributionMessage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StatementDistributionMessage

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

Formats the value using the given formatter.

impl Decode for StatementDistributionMessage

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 StatementDistributionMessage

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, 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 From<StatementDistributionMessage> for ValidationProtocol

fn from(original: StatementDistributionMessage) -> ValidationProtocol

Converts to this type from the input type.

impl PartialEq<StatementDistributionMessage> for StatementDistributionMessage

fn eq(&self, other: &StatementDistributionMessage) -> 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.
