Enum polkadot_primitives::v8::ConsensusLog

pub enum ConsensusLog {
    ParaUpgradeCode(Id, ValidationCodeHash),
    ParaScheduleUpgradeCode(Id, ValidationCodeHash, BlockNumber),
    ForceApprove(BlockNumber),
    Revert(BlockNumber),
}

A consensus log item for polkadot validation. To be used with POLKADOT_ENGINE_ID.

Variants

ParaUpgradeCode(Id, ValidationCodeHash)

A parachain upgraded its code.

ParaScheduleUpgradeCode(Id, ValidationCodeHash, BlockNumber)

A parachain scheduled a code upgrade.

ForceApprove(BlockNumber)

Governance requests to auto-approve every candidate included up to the given block number in the current chain, inclusive.

Revert(BlockNumber)

A signal to revert the block number in the same chain as the header this digest is part of and all of its descendants.

It is a no-op for a block to contain a revert digest targeting its own number or a higher number.

In practice, these are issued when on-chain logic has detected an invalid parachain block within its own chain, due to a dispute.

Implementations

impl ConsensusLog

pub fn from_digest_item(digest_item: &DigestItem) -> Result<Option<Self>, Error>

Attempt to convert a reference to a generic digest item into a consensus log.

Trait Implementations

impl Clone for ConsensusLog

fn clone(&self) -> ConsensusLog

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Decode for ConsensusLog

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 ConsensusLog

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<ConsensusLog> for DigestItem

fn from(c: ConsensusLog) -> DigestItem

Converts to this type from the input type.

impl PartialEq for ConsensusLog

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