Storage

The following sections contain Storage methods are part of the default Substrate runtime. On the api, these are exposed via api.query.<module>.<method>.

(NOTE: These were generated from a static/snapshot view of a recent default Substrate runtime. Some items may not be available in older nodes, or in any customized implementations.)

assetConversion​

nextPoolAssetId(): Option<u32>​

  • interface: api.query.assetConversion.nextPoolAssetId
  • summary: Stores the PoolAssetId that is going to be used for the next lp token. This gets incremented whenever a new lp pool is created.

pools((FrameSupportTokensFungibleUnionOfNativeOrWithId,FrameSupportTokensFungibleUnionOfNativeOrWithId)): Option<PalletAssetConversionPoolInfo>​

  • interface: api.query.assetConversion.pools
  • summary: Map from PoolAssetId to PoolInfo. This establishes whether a pool has been officially created rather than people sending tokens directly to a pool's public account.

assetRate​

conversionRateToNative(u32): Option<u128>​

  • interface: api.query.assetRate.conversionRateToNative

  • summary: Maps an asset to its fixed point representation in the native balance.

  • interface: api.query.babe.currentSlot
  • summary: Current slot number.

epochConfig(): Option<SpConsensusBabeBabeEpochConfiguration>​

epochIndex(): u64​

  • interface: api.query.babe.epochIndex
  • summary: Current epoch index.

epochStart(): (u32,u32)​

  • interface: api.query.babe.epochStart
  • summary: The block numbers when the last and current epoch have started, respectively N-1 and N. NOTE: We track this is in order to annotate the block number when a given pool of entropy was fixed (i.e. it was known to chain observers). Since epochs are defined in slots, which may be skipped, the block numbers may not line up with the slot numbers.

genesisSlot(): u64​

  • interface: api.query.babe.genesisSlot
  • summary: The slot at which the first epoch actually started. This is 0 until the first block of the chain.

initialized(): Option<Option<SpConsensusBabeDigestsPreDigest>>​

lateness(): u32​

  • interface: api.query.babe.lateness

  • summary: How late the current block is compared to its parent.

    This entry is populated as part of block execution and is cleaned up on block finalization. Querying this storage entry outside of block execution context should always yield zero.

nextAuthorities(): Vec<(SpConsensusBabeAppPublic,u64)>​

  • interface: api.query.babe.nextAuthorities
  • summary: Next epoch authorities.

nextEpochConfig(): Option<SpConsensusBabeBabeEpochConfiguration>​

  • interface: api.query.babe.nextEpochConfig

pendingEpochConfigChange(): Option<SpConsensusBabeDigestsNextConfigDescriptor>​

  • interface: api.query.babe.pendingEpochConfigChange
  • summary: Pending epoch configuration change that will be applied when the next epoch is enacted.

randomness(): [u8;32]​

  • interface: api.query.babe.randomness

  • summary: The epoch randomness for the current epoch.

    Security​

    This MUST NOT be used for gambling, as it can be influenced by a malicious validator in the short term. It MAY be used in many cryptographic protocols, however, so long as one remembers that this (like everything else on-chain) it is public. For example, it can be used where a number is needed that cannot have been chosen by an adversary, for purposes such as public-coin zero-knowledge proofs.

segmentIndex(): u32​

  • interface: api.query.babe.segmentIndex

  • summary: Randomness under construction.

    We make a trade-off between storage accesses and list length. We store the under-construction randomness in segments of up to UNDER_CONSTRUCTION_SEGMENT_LENGTH.

    Once a segment reaches this length, we begin the next one. We reset all segments and return to 0 at the beginning of every epoch.

skippedEpochs(): Vec<(u64,u32)>​

  • interface: api.query.babe.skippedEpochs

  • summary: A list of the last 100 skipped epochs and the corresponding session index when the epoch was skipped.

    This is only used for validating equivocation proofs. An equivocation proof must contains a key-ownership proof for a given session, therefore we need a way to tie together sessions and epoch indices, i.e. we need to validate that a validator was the owner of a given key on a given session, and what the active epoch index was during that session.

underConstruction(u32): Vec<[u8;32]>​

  • interface: api.query.babe.underConstruction
  • summary: TWOX-NOTE: SegmentIndex is an increasing integer, so this is okay.

balances​

account(AccountId32): PalletBalancesAccountData​

  • interface: api.query.balances.account

  • summary: The Balances pallet example of storing the balance of an account.

    Example​

    nocompile impl pallet_balances::Config for Runtime { type AccountStore = StorageMapShim<Self::Account<Runtime>, frame_system::Provider<Runtime>, AccountId, Self::AccountData<Balance>> }

    You can also store the balance of an account in the System pallet.

    Example​

    nocompile impl pallet_balances::Config for Runtime { type AccountStore = System }

    But this comes with tradeoffs, storing account balances in the system pallet stores frame_system data alongside the account data contrary to storing account balances in the Balances pallet, which uses a StorageMap to store balances data only. NOTE: This is only used in the case that this pallet is used to store balances.

freezes(AccountId32): Vec<FrameSupportTokensMiscIdAmountRuntimeFreezeReason>​

  • interface: api.query.balances.freezes
  • summary: Freeze locks on account balances.

holds(AccountId32): Vec<FrameSupportTokensMiscIdAmountRuntimeHoldReason>​

  • interface: api.query.balances.locks

  • summary: Any liquidity locks on some account balances. NOTE: Should only be accessed when setting, changing and freeing a lock.

    Use of locks is deprecated in favour of freezes. See https://github.com/paritytech/substrate/pull/12951/

reserves(AccountId32): Vec<PalletBalancesReserveData>​

  • interface: api.query.balances.reserves

  • summary: Named reserves on some account balances.

    Use of reserves is deprecated in favour of holds. See https://github.com/paritytech/substrate/pull/12951/

totalIssuance(): u128​

  • interface: api.query.balances.totalIssuance
  • summary: The total units issued in the system.

  • interface: api.query.beefy.nextAuthorities
  • summary: Authorities set scheduled to be used with the next session

setIdSession(u64): Option<u32>​

  • interface: api.query.beefy.setIdSession

  • summary: A mapping from BEEFY set ID to the index of the most recent session for which its members were responsible.

    This is only used for validating equivocation proofs. An equivocation proof must contains a key-ownership proof for a given session, therefore we need a way to tie together sessions and BEEFY set ids, i.e. we need to validate that a validator was the owner of a given key on a given session, and what the active set ID was during that session.

    TWOX-NOTE: ValidatorSetId is not under user control.

validatorSetId(): u64​

  • interface: api.query.beefy.validatorSetId
  • summary: The current validator set id

contracts​

codeInfoOf(H256): Option<PalletContractsWasmCodeInfo>​

  • interface: api.query.contracts.codeInfoOf
  • summary: A mapping from a contract's code hash to its code info.

contractInfoOf(AccountId32): Option<PalletContractsStorageContractInfo>​

  • interface: api.query.contracts.contractInfoOf

  • summary: The code associated with a given account.

    TWOX-NOTE: SAFE since AccountId is a secure hash.

deletionQueue(u32): Option<Bytes>​

  • interface: api.query.contracts.deletionQueue

  • summary: Evicted contracts that await child trie deletion.

    Child trie deletion is a heavy operation depending on the amount of storage items stored in said trie. Therefore this operation is performed lazily in on_idle.

deletionQueueCounter(): PalletContractsStorageDeletionQueueManager​

  • interface: api.query.contracts.deletionQueueCounter
  • summary: A pair of monotonic counters used to track the latest contract marked for deletion and the latest deleted contract in queue.

migrationInProgress(): Option<Bytes>​

  • interface: api.query.contracts.migrationInProgress
  • summary: A migration can span across multiple blocks. This storage defines a cursor to track the progress of the migration, enabling us to resume from the last completed position.

nonce(): u64​

  • interface: api.query.contracts.nonce

  • summary: This is a monotonic counter incremented on contract instantiation.

    This is used in order to generate unique trie ids for contracts. The trie id of a new contract is calculated from hash(account_id, nonce). The nonce is required because otherwise the following sequence would lead to a possible collision of storage:

    1. Create a new contract. 2. Terminate the contract. 3. Immediately recreate the contract with the same account_id.

      This is bad because the contents of a trie are deleted lazily and there might be storage of the old instantiation still in it when the new contract is created. Please note that we can't replace the counter by the block number because the sequence above can happen in the same block. We also can't keep the account counter in memory only because storage is the only way to communicate across different extrinsics in the same block.

      Note​

      Do not use it to determine the number of contracts. It won't be decremented if a contract is destroyed.

pristineCode(H256): Option<Bytes>​

  • interface: api.query.contracts.pristineCode
  • summary: A mapping from a contract's code hash to its code.

convictionVoting​

classLocksFor(AccountId32): Vec<(u16,u128)>​

  • interface: api.query.convictionVoting.classLocksFor
  • summary: The voting classes which have a non-zero lock requirement and the lock amounts which they require. The actual amount locked on behalf of this pallet should always be the maximum of this list.

votingFor(AccountId32, u16): PalletConvictionVotingVoteVoting​

  • interface: api.query.convictionVoting.votingFor
  • summary: All voting for a particular voter in a particular voting class. We store the balance for the number of votes that we have recorded.

    TWOX-NOTE: Safe, as increasing integer keys are safe.

lastTabledWasExternal(): bool​

  • interface: api.query.democracy.lastTabledWasExternal
  • summary: True if the last referendum tabled was submitted externally. False if it was a public proposal.

lowestUnbaked(): u32​

  • interface: api.query.democracy.lowestUnbaked
  • summary: The lowest referendum index representing an unbaked referendum. Equal to ReferendumCount if there isn't a unbaked referendum.

metadataOf(PalletDemocracyMetadataOwner): Option<H256>​

nextExternal(): Option<(FrameSupportPreimagesBounded,PalletDemocracyVoteThreshold)>​

  • interface: api.query.democracy.nextExternal

  • summary: The referendum to be tabled whenever it would be valid to table an external proposal. This happens when a referendum needs to be tabled and one of two conditions are met:

  • interface: api.query.democracy.referendumCount
  • summary: The next free referendum index, aka the number of referenda started so far.

referendumInfoOf(u32): Option<PalletDemocracyReferendumInfo>​

  • interface: api.query.democracy.referendumInfoOf

  • summary: Information concerning any given referendum.

    TWOX-NOTE: SAFE as indexes are not under an attacker’s control.

votingOf(AccountId32): PalletDemocracyVoteVoting​

  • interface: api.query.democracy.votingOf

  • summary: All votes for a particular voter. We store the balance for the number of votes that we have recorded. The second item is the total amount of delegations, that will be added.

    TWOX-NOTE: SAFE as AccountIds are crypto hashes anyway.

electionProviderMultiPhase​

currentPhase(): PalletElectionProviderMultiPhasePhase​

  • interface: api.query.electionProviderMultiPhase.currentPhase
  • summary: Current phase.

desiredTargets(): Option<u32>​

  • interface: api.query.electionProviderMultiPhase.desiredTargets

  • summary: Desired number of targets to elect for this round.

    Only exists when [Snapshot] is present. Note: This storage type must only be mutated through [SnapshotWrapper].

minimumUntrustedScore(): Option<SpNposElectionsElectionScore>​

  • interface: api.query.electionProviderMultiPhase.minimumUntrustedScore

  • summary: The minimum score that each 'untrusted' solution must attain in order to be considered feasible.

    Can be set via set_minimum_untrusted_score.

queuedSolution(): Option<PalletElectionProviderMultiPhaseReadySolution>​

  • interface: api.query.electionProviderMultiPhase.queuedSolution

  • summary: Current best solution, signed or unsigned, queued to be returned upon elect.

    Always sorted by score.

round(): u32​

  • interface: api.query.electionProviderMultiPhase.round

  • summary: Internal counter for the number of rounds.

    This is useful for de-duplication of transactions submitted to the pool, and general diagnostics of the pallet.

    This is merely incremented once per every time that an upstream elect is called.

signedSubmissionIndices(): Vec<(SpNposElectionsElectionScore,u32,u32)>​

  • interface: api.query.electionProviderMultiPhase.signedSubmissionIndices

  • summary: A sorted, bounded vector of (score, block_number, index), where each index points to a value in SignedSubmissions.

    We never need to process more than a single signed submission at a time. Signed submissions can be quite large, so we're willing to pay the cost of multiple database accesses to access them one at a time instead of reading and decoding all of them at once.

signedSubmissionNextIndex(): u32​

  • interface: api.query.electionProviderMultiPhase.signedSubmissionNextIndex

  • summary: The next index to be assigned to an incoming signed submission.

    Every accepted submission is assigned a unique index; that index is bound to that particular submission for the duration of the election. On election finalization, the next index is reset to 0.

    We can't just use SignedSubmissionIndices.len(), because that's a bounded set; past its capacity, it will simply saturate. We can't just iterate over SignedSubmissionsMap, because iteration is slow. Instead, we store the value here.

signedSubmissionsMap(u32): Option<PalletElectionProviderMultiPhaseSignedSignedSubmission>​

  • interface: api.query.electionProviderMultiPhase.signedSubmissionsMap

  • summary: Unchecked, signed solutions.

    Together with SubmissionIndices, this stores a bounded set of SignedSubmissions while allowing us to keep only a single one in memory at a time.

    Twox note: the key of the map is an auto-incrementing index which users cannot inspect or affect; we shouldn't need a cryptographically secure hasher.

snapshot(): Option<PalletElectionProviderMultiPhaseRoundSnapshot>​

  • interface: api.query.electionProviderMultiPhase.snapshot

  • summary: Snapshot data of the round.

    This is created at the beginning of the signed phase and cleared upon calling elect. Note: This storage type must only be mutated through [SnapshotWrapper].

snapshotMetadata(): Option<PalletElectionProviderMultiPhaseSolutionOrSnapshotSize>​

  • interface: api.query.electionProviderMultiPhase.snapshotMetadata

  • summary: The metadata of the [RoundSnapshot]

    Only exists when [Snapshot] is present. Note: This storage type must only be mutated through [SnapshotWrapper].

elections​

candidates(): Vec<(AccountId32,u128)>​

  • interface: api.query.elections.candidates

  • summary: The present candidate list. A current member or runner-up can never enter this vector and is always implicitly assumed to be a candidate.

    Second element is the deposit.

    Invariant: Always sorted based on account id.

electionRounds(): u32​

  • interface: api.query.elections.electionRounds
  • summary: The total number of vote rounds that have happened, excluding the upcoming one.

members(): Vec<PalletElectionsPhragmenSeatHolder>​

  • interface: api.query.elections.members

  • summary: The current elected members.

    Invariant: Always sorted based on account id.

runnersUp(): Vec<PalletElectionsPhragmenSeatHolder>​

  • interface: api.query.elections.runnersUp

  • summary: The current reserved runners-up.

    Invariant: Always sorted based on rank (worse to best). Upon removal of a member, the last (i.e. best) runner-up will be replaced.

voting(AccountId32): PalletElectionsPhragmenVoter​

  • interface: api.query.elections.voting

  • summary: Votes and locked stake of a particular voter.

    TWOX-NOTE: SAFE as AccountId is a crypto hash.

fastUnstake​

counterForQueue(): u32​

  • interface: api.query.fastUnstake.counterForQueue
  • summary: Counter for the related counted storage map

erasToCheckPerBlock(): u32​

  • interface: api.query.fastUnstake.erasToCheckPerBlock

  • summary: Number of eras to check per block.

    If set to 0, this pallet does absolutely nothing. Cannot be set to more than [Config::MaxErasToCheckPerBlock].

    Based on the amount of weight available at [Pallet::on_idle], up to this many eras are checked. The checking is represented by updating [UnstakeRequest::checked], which is stored in [Head].

trashData(u32): Option<[u8;1024]>​

  • interface: api.query.glutton.trashData

  • summary: Storage map used for wasting proof size.

    It contains no meaningful data - hence the name "Trash". The maximal number of entries is set to 65k, which is just below the next jump at 16^4. This is important to reduce the proof size benchmarking overestimate. The assumption here is that we won't have more than 65k * 1KiB = 65MiB of proof size wasting in practice. However, this limit is not enforced, so the pallet would also work out of the box with more entries, but its benchmarked proof weight would possibly be underestimated in that case.

  • interface: api.query.imOnline.heartbeatAfter

  • summary: The block number after which it's ok to send heartbeats in the current session.

    At the beginning of each session we set this to a value that should fall roughly in the middle of the session duration. The idea is to first wait for the validators to produce a block in the current session, so that the heartbeat later on will not be necessary.

    This value will only be used as a fallback if we fail to get a proper session progress estimate from NextSessionRotation, as those estimates should be more accurate then the value we calculate for HeartbeatAfter.

  • interface: api.query.staking.nominators

  • summary: The map from nominator stash key to their nomination preferences, namely the validators that they wish to support.

    Note that the keys of this storage map might become non-decodable in case the account's [NominationsQuota::MaxNominations] configuration is decreased. In this rare case, these nominators are still existent in storage, their key is correct and retrievable (i.e. contains_key indicates that they exist), but their value cannot be decoded. Therefore, the non-decodable nominators will effectively not-exist, until they re-submit their preferences such that it is within the bounds of the newly set Config::MaxNominations.

    This implies that ::iter_keys().count() and ::iter().count() might return different values for this map. Moreover, the main ::count() is aligned with the former, namely the number of keys that exist.

    Lastly, if any of the nominators become non-decodable, they can be chilled immediately via [Call::chill_other] dispatchable by anyone.
