Enum cumulus_primitives_core::relay_chain::v2::ConsensusLog

pub enum ConsensusLog {
    ParaUpgradeCode(Id, ValidationCodeHash),
    ParaScheduleUpgradeCode(Id, ValidationCodeHash, u32),
    ForceApprove(u32),
    Revert(u32),
}

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

Variants

ParaUpgradeCode(Id, ValidationCodeHash)

A parachain or parathread upgraded its code.

ParaScheduleUpgradeCode(Id, ValidationCodeHash, u32)

A parachain or parathread scheduled a code upgrade.

ForceApprove(u32)

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

Revert(u32)

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<ConsensusLog>, 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>(
    __codec_input_edqy: &mut __CodecInputEdqy
) -> Result<ConsensusLog, Error>where
    __CodecInputEdqy: Input,

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 Encode for ConsensusLog

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

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 PartialEq<ConsensusLog> 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.
