Module vstaging

Staging Primitives.

Modules

async_backing

Async backing primitives

Structs

BackedCandidate

A backed (or backable, depending on context) candidate.

CandidateDescriptorV2

A unique descriptor of the candidate receipt.

CandidateReceiptV2

A candidate-receipt at version 2.

CandidateUMPSignals

User-friendly representation of a candidate’s UMP signals.

ClaimQueueOffset

An offset in the relay chain claim queue.

CommittedCandidateReceiptV2

A candidate-receipt with commitments directly included.

CoreSelector

A strictly increasing sequence number, typically this would be the least significant byte of the block number.

DisputeProof

We store most of the information about a lost dispute on chain. This struct is required to identify and verify it.

InherentData

Parachains inherent-data passed into the runtime by a block author

InternalVersion

A type representing the version of the candidate descriptor and internal version number.

OccupiedCore

Information about a core which is currently occupied.

PendingSlashes

Slashes that are waiting to be applied once we have validator key identification.

ScrapedOnChainVotes

Scraped runtime backing votes and resolved disputes.

Enums

CandidateDescriptorVersion

A type representing the version of the candidate descriptor.

CandidateEvent

An event concerning a candidate.

CommittedCandidateReceiptError

CommittedCandidateReceiptError construction errors.

CoreState

The state of a particular availability core.

DisputeOffenceKind

Supercedes the old ‘SlashingOffenceKind’ enum.

UMPSignal

Signals that a parachain can send to the relay chain via the UMP queue.

Constants

DEFAULT_CLAIM_QUEUE_OFFSET

The default claim queue offset to be used if it’s not configured/accessible in the parachain runtime

UMP_SEPARATOR

Separator between XCM and UMPSignal.

Traits

MutateDescriptorV2

A trait to allow changing the descriptor field values in tests.

Functions

skip_ump_signals

Utility function for skipping the ump signals.

transpose_claim_queue

Returns a mapping between the para id and the core indices assigned at different depths in the claim queue.

Type Aliases

ApprovedPeerId

Approved PeerId type. PeerIds in polkadot should typically be 32 bytes long but for identity multihash can go up to 64. Cannot reuse the PeerId type definition from the networking code as it’s too generic and extensible.

TransposedClaimQueue

The claim queue mapped by parachain id.
