A request to the Runtime API subsystem.

Variants

Version(RuntimeApiSender<u32>)

Get the version of the runtime API, if any.

Authorities(RuntimeApiSender<Vec<AuthorityDiscoveryId>>)

Get the next, current and some previous authority discovery set deduplicated.

Validators(RuntimeApiSender<Vec<ValidatorId>>)

Get the current validator set.

ValidatorGroups(RuntimeApiSender<(Vec<Vec<ValidatorIndex>>, GroupRotationInfo)>)

Get the validator groups and group rotation info.

AvailabilityCores(RuntimeApiSender<Vec<CoreState>>)

Get information on all availability cores.

PersistedValidationData(ParaId, OccupiedCoreAssumption, RuntimeApiSender<Option<PersistedValidationData>>)

Get the persisted validation data for a particular para, taking the given OccupiedCoreAssumption, which will inform on how the validation data should be computed if the para currently occupies a core.

AssumedValidationData(ParaId, Hash, RuntimeApiSender<Option<(PersistedValidationData, ValidationCodeHash)>>)

Get the persisted validation data for a particular para along with the current validation code hash, matching the data hash against an expected one.

CheckValidationOutputs(ParaId, CandidateCommitments, RuntimeApiSender<bool>)

Sends back true if the validation outputs pass all acceptance criteria checks.

SessionIndexForChild(RuntimeApiSender<SessionIndex>)

Get the session index that a child of the block will have.

ValidationCode(ParaId, OccupiedCoreAssumption, RuntimeApiSender<Option<ValidationCode>>)

Get the validation code for a para, taking the given OccupiedCoreAssumption, which will inform on how the validation data should be computed if the para currently occupies a core.

ValidationCodeByHash(ValidationCodeHash, RuntimeApiSender<Option<ValidationCode>>)

Get validation code by its hash, either past, current or future code can be returned, as long as state is still available.

CandidatePendingAvailability(ParaId, RuntimeApiSender<Option<CommittedCandidateReceipt>>)

Get a the candidate pending availability for a particular parachain by parachain / core index

CandidateEvents(RuntimeApiSender<Vec<CandidateEvent>>)

Get all events concerning candidates (backing, inclusion, time-out) in the parent of the block in whose state this request is executed.

SessionInfo(SessionIndex, RuntimeApiSender<Option<SessionInfo>>)

Get the session info for the given session, if stored.

DmqContents(ParaId, RuntimeApiSender<Vec<InboundDownwardMessage<BlockNumber>>>)

Get all the pending inbound messages in the downward message queue for a para.

InboundHrmpChannelsContents(ParaId, RuntimeApiSender<BTreeMap<ParaId, Vec<InboundHrmpMessage<BlockNumber>>>>)

Get the contents of all channels addressed to the given recipient. Channels that have no messages in them are also included.

CurrentBabeEpoch(RuntimeApiSender<BabeEpoch>)

Get information about the BABE epoch the block was included in.

FetchOnChainVotes(RuntimeApiSender<Option<ScrapedOnChainVotes>>)

Get all disputes in relation to a relay parent.

SubmitPvfCheckStatement(PvfCheckStatement, ValidatorSignature, RuntimeApiSender<()>)

Submits a PVF pre-checking statement into the transaction pool.

PvfsRequirePrecheck(RuntimeApiSender<Vec<ValidationCodeHash>>)

Returns code hashes of PVFs that require pre-checking by validators in the active set.

ValidationCodeHash(ParaId, OccupiedCoreAssumption, RuntimeApiSender<Option<ValidationCodeHash>>)

Get the validation code used by the specified para, taking the given OccupiedCoreAssumption, which will inform on how the validation data should be computed if the para currently occupies a core.

Disputes(RuntimeApiSender<Vec<(SessionIndex, CandidateHash, DisputeState<BlockNumber>)>>)

Returns all on-chain disputes at given block number. Available in v3.
