Crate sp_domains

Primitives for domains pallet.

Modules

• bundle_producer_election
• core_api
• extrinsics
• merkle_tree
• proof_provider_and_verifier
• storage
• valued_trie

Structs

• BlockFees
• Bundle
  Domain bundle.
• BundleDigest
  A digest of the bundle
• BundleHeader
• DomainAllowlistUpdates
  Domain chains allowlist updates.
• DomainBlockLimit
• DomainBundleLimit
• DomainId
  Unique identifier of a domain.
• DomainInstanceData
  DomainInstanceData is used to construct the genesis storage of domain instance chain
• DomainSudoCall
  Domain Sudo runtime call. This structure exists because we need to generate a storage proof for FP and Storage shouldn’t be None. So each domain must always hold this value even if there is an empty runtime call inside
• ExecutionReceipt
  Receipt of a domain block execution.
• GenesisDomain
• InboxedBundle
  InboxedBundle represents a bundle that was successfully submitted to the consensus chain
• OperatorKey
  A type that implements BoundToRuntimeAppPublic, used for operator signing key.
• OperatorSigningKeyProofOfOwnershipData
  Preimage to verify the proof of ownership of Operator Signing key. Operator owner is used to ensure the signature is used by anyone except the owner of the Signing key pair.
• ProofOfElection
• RuntimeObject
• SealedBundleHeader
  Header of bundle.
• SealedSingletonReceipt
• SingletonReceipt
  Singleton receipt submit along when there is a gap between domain_best_number and HeadReceiptNumber
• Transfers
  Type that holds the transfers(in/out) for a given chain.

Enums

• BundleValidity
• ChainId
  Identifier of a chain.
• DomainDigestItem
  Domains specific digest item.
• DomainsHoldIdentifier
  Domains specific Identifier for Balances holds.
• ExtrinsicDigest
  Represents the extrinsic either as full data or hash of the data.
• InvalidBundleType
  Bundle invalidity type
• InvalidReceipt
  Receipt invalidity type.
• MessengerHoldIdentifier
  Messenger specific hold identifier
• OperatorAllowList
  Type that represents an operator allow list for Domains.
• PermissionedActionAllowedBy
  Permissioned actions allowed by either specific accounts or anyone.
• ReceiptValidity
• RuntimeType
  Types of runtime pallet domains currently supports
• StakingHoldIdentifier
  Staking specific hold identifier

Constants

• DOMAIN_EXTRINSICS_SHUFFLING_SEED_SUBJECT
  Extrinsics shuffling seed
• DOMAIN_STORAGE_FEE_MULTIPLIER
• EMPTY_EXTRINSIC_ROOT
  Empty extrinsics root.
• INITIAL_DOMAIN_TX_RANGE
  Initial tx range = U256::MAX / INITIAL_DOMAIN_TX_RANGE.
• KEY_TYPE
  Key type for Operator.

Traits

• BundleProducerElectionApi
• DomainBundleSubmitted
  Post hook to know if the domain had bundle submitted in the previous block.
• DomainOwner
  Trait to check domain owner.
• DomainsApi
  API necessary for domains pallet.
• DomainsDigestItem
  Domains specific digest items.
• DomainsTransfersTracker
  Trait that tracks the balances on Domains.
• OnChainRewards
  Hook to handle chain rewards.
• OnDomainInstantiated
  A hook to call after a domain is instantiated

Functions

• calculate_max_bundle_weight_and_size
  Calculates the max bundle weight and size
• derive_domain_block_hash
• domain_account_storage_key
  Account info on frame_system on Domains
• domain_total_issuance_storage_key
  Total issuance storage for Domains.
• dummy_opaque_bundle
• operator_block_fees_final_key
  This is a representation of actual Block Fees storage in pallet-block-fees. Any change in key or value there should be changed here accordingly.
• self_domain_id_storage_key
  The storage key of the SelfDomainId storage item in the pallet-domain-id
• signer_in_tx_range
  Checks if the signer Id hash is within the tx range
• system_digest_final_key
  Digest storage key in frame_system. Unfortunately, the digest storage is private and not possible to derive the key from it directly.

Type Aliases

• ChannelId
  Channel identity.
• EpochIndex
  Type representing domain epoch.
• ExecutionReceiptFor
• ExtrinsicsRoot
  The Trie root of all extrinsics included in a bundle.
• HeaderHashFor
  Type alias for Header hash.
• HeaderHashingFor
  Type alias for Header Hashing.
• HeaderNumberFor
  Type alias for Header number.
• OpaqueBundle
  Bundle with opaque extrinsics.
• OpaqueBundles
  List of OpaqueBundle.
• OperatorId
  Type representing operator ID
• OperatorPair
  An operator authority keypair. Necessarily equivalent to the schnorrkel public key used in the main executor module. If that ever changes, then this must, too.
• OperatorPublicKey
  An operator authority identifier.
• OperatorSignature
  An operator authority signature.
• RuntimeId
  Type representing the runtime ID.
• StakeWeight
  Stake weight in the domain bundle election.
