Struct CommittedCandidateReceipt 

pub struct CommittedCandidateReceipt<H = H256> {
    pub descriptor: CandidateDescriptorV2<H>,
    pub commitments: CandidateCommitments,
}

A candidate-receipt with commitments directly included.

Fields

descriptor: CandidateDescriptorV2<H>

The descriptor of the candidate.

commitments: CandidateCommitments

The commitments of the candidate receipt.

Implementations

impl<H> CommittedCandidateReceiptV2<H>

where H: Clone,

pub fn to_plain(&self) -> CandidateReceiptV2<H>

Transforms this into a plain CandidateReceipt.

pub fn hash(&self) -> CandidateHash

where H: Encode,

Computes the hash of the committed candidate receipt.

This computes the canonical hash, not the hash of the directly encoded data. Thus this is a shortcut for candidate.to_plain().hash().

pub fn corresponds_to(&self, receipt: &CandidateReceiptV2<H>) -> bool

where H: PartialEq,

Does this committed candidate receipt corresponds to the given CandidateReceiptV2?

impl<H> CommittedCandidateReceiptV2<H>

where H: Copy + AsRef<[u8]>,

pub fn parse_ump_signals( &self, cores_per_para: &BTreeMap<Id, BTreeMap<u8, BTreeSet<CoreIndex>>>, ) -> Result<CandidateUMPSignals, CommittedCandidateReceiptError>

Performs checks on the UMP signals and returns them.

Also checks if descriptor core index is equal to the committed core index.

Params:

• cores_per_para is a claim queue snapshot at the candidate’s relay parent, stored as a mapping between ParaId and the cores assigned per depth.

NOTE: This must only be called in the runtime and backing - never in approval voting nor disputes! At least not as long as nodes exist which don’t understand v3 candidate descriptors. Not checking there is fine, because it is checked by the runtime - if it can be disputed, it has been checked already!

impl Ord for CommittedCandidateReceiptV2

fn cmp(&self, other: &CommittedCandidateReceiptV2) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,
