  • interface: api.query.system.allExtrinsicsLen
  • summary: Total length (in bytes) for all extrinsics put together, for the current block.

blockHash(BlockNumber): Hash#

  • interface: api.query.system.blockHash
  • summary: Map of block numbers to block hashes.

blockWeight(): ConsumedWeight#

  • interface: api.query.system.blockWeight
  • summary: The current weight for the block.

digest(): DigestOf#

  • interface: api.query.system.digest

eventCount(): EventIndex#

  • interface: api.query.system.eventCount
  • summary: The number of events in the Events<T> list.

events(): Vec<EventRecord>#

  • interface: api.query.system.events
  • summary: Events deposited for the current block.

eventTopics(Hash): Vec<(BlockNumber,EventIndex)>#

  • interface: api.query.system.eventTopics

  • summary: Mapping between a topic (represented by T::Hash) and a vector of indexes of events in the <Events<T>> list.

    All topic vectors have deterministic storage locations depending on the topic. This allows light-clients to leverage the changes trie storage tracking mechanism and in case of changes fetch the list of events of interest.

    The value has the type (T::BlockNumber, EventIndex) because if we used only just the EventIndex then in case if the topic has the same contents on the next block no notification will be triggered thus the event might be lost.

executionPhase(): Option<Phase>#

  • interface: api.query.system.executionPhase
  • summary: The execution phase of the block.

extrinsicCount(): Option<u32>#

  • interface: api.query.system.extrinsicCount
  • summary: Total extrinsics count for the current block.

extrinsicData(u32): Bytes#

  • summary: Extrinsics data for the current block (maps an extrinsic's index to its data).

lastRuntimeUpgrade(): Option<LastRuntimeUpgradeInfo>#

  • interface: api.query.system.lastRuntimeUpgrade
  • summary: Stores the spec_version and spec_name of when the last runtime upgrade happened.

number(): BlockNumber#

  • interface: api.query.system.number
  • summary: The current block number being processed. Set by execute_block.

parentHash(): Hash#

  • interface: api.query.system.parentHash
  • summary: Hash of the previous block.

upgradedToDualRefCount(): bool#

  • interface: api.query.system.upgradedToDualRefCount
  • summary: True if we have upgraded so that AccountInfo contains two types of RefCount. False (default) if not.

upgradedToU32RefCount(): bool#

  • interface: api.query.system.upgradedToU32RefCount
  • summary: True if we have upgraded so that type RefCount is u32. False (default) if not.

technicalCommittee#

members(): Vec<AccountId>#

  • interface: api.query.technicalCommittee.members
  • summary: The current members of the collective. This is stored sorted (just by value).

prime(): Option<AccountId>#

  • interface: api.query.technicalCommittee.prime
  • summary: The prime member that helps determine the default vote behavior in case of absentations.

proposalCount(): u32#

  • interface: api.query.technicalCommittee.proposalCount

proposalOf(Hash): Option<Proposal>#

  • interface: api.query.technicalCommittee.proposalOf
  • summary: Actual proposal for a given hash, if it's current.

proposals(): Vec<Hash>#

  • interface: api.query.technicalCommittee.proposals
  • summary: The hashes of the active proposals.

voting(Hash): Option<Votes>#

  • interface: api.query.technicalCommittee.voting
  • summary: Votes on a given proposal, if it is ongoing.

technicalMembership#

members(): Vec<AccountId>#

  • interface: api.query.technicalMembership.members
  • summary: The current membership, stored as an ordered Vec.

prime(): Option<AccountId>#

  • interface: api.query.technicalMembership.prime
  • summary: The current prime member, if one exists.

timestamp#

didUpdate(): bool#

  • interface: api.query.timestamp.didUpdate
  • summary: Did the timestamp get updated in this block?

now(): Moment#

  • interface: api.query.timestamp.now
  • summary: Current time for the current block.

tips#

reasons(Hash): Option<Bytes>#

  • interface: api.query.tips.reasons
  • summary: Simple preimage lookup from the reason's hash to the original data. Again, has an insecure enumerable hash since the key is guaranteed to be the result of a secure hash.

tips(Hash): Option<OpenTip>#

  • interface: api.query.tips.tips
  • summary: TipsMap that are not yet completed. Keyed by the hash of (reason, who) from the value. This has the insecure enumerable hash function since the key itself is already guaranteed to be a secure hash.

transactionPayment#

nextFeeMultiplier(): Multiplier#

  • interface: api.query.transactionPayment.nextFeeMultiplier

storageVersion(): Releases#

  • interface: api.query.transactionPayment.storageVersion
