Enum polkadot_node_network_protocol::v1::StatementDistributionMessage

pub enum StatementDistributionMessage {
    Statement(Hash, UncheckedSignedFullStatement),
    LargeStatement(StatementMetadata),
}

Network messages used by the statement distribution subsystem.

Variants

Statement(Hash, UncheckedSignedFullStatement)

A signed full statement under a given relay-parent.

LargeStatement(StatementMetadata)

Seconded statement with large payload (e.g. containing a runtime upgrade).

We only gossip the hash in that case, actual payloads can be fetched from sending node via request/response.

Implementations

impl StatementDistributionMessage

pub fn get_fingerprint(&self) -> (CompactStatement, ValidatorIndex)

Get fingerprint describing the contained statement uniquely.

pub fn get_signature(&self) -> ValidatorSignature

Get the signature from the statement.

pub fn get_relay_parent(&self) -> Hash

Get contained relay parent.

pub fn is_large_statement(&self) -> bool

Whether this message contains a large statement.

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>

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 From<StatementDistributionMessage> for ValidationProtocol

fn from(original: StatementDistributionMessage) -> ValidationProtocol

Converts to this type from the input type.

impl PartialEq 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.
