Crate bp_bridge_hub_cumulus

Primitives of all Cumulus-based bridge hubs.

Structs

• AccountInfoStorageMapKeyProvider
  Provides a storage key for account data.
• BlockExecutionWeight
  Importing a block with 0 Extrinsics.
• BlockLength
  Size limit of the Cumulus-based bridge hub blocks.
• BlockWeights
  Weight limit of the Cumulus-based bridge hub blocks.
• BlockWeightsForAsyncBacking
  Weight limit of the Cumulus-based bridge hub blocks when async backing is enabled.
• ExtrinsicBaseWeight
  Executing a NO-OP System::remarks Extrinsic.
• Perbill
  A fixed point representation of a number in the range [0, 1].

Constants

• AVERAGE_BLOCK_INTERVAL
  Average block interval in Cumulus-based parachains.
• AVERAGE_ON_INITIALIZE_RATIO
  All cumulus bridge hubs assume that about 5 percent of the block weight is consumed by on_initialize handlers. This is used to limit the maximal weight of a single extrinsic.
• EXTRA_STORAGE_PROOF_SIZE
  Number of extra bytes (excluding size of storage value itself) of storage proof, built at Polkadot-like chain. This mostly depends on number of entries in the storage trie. Some reserve is reserved to account future chain growth.
• MAX_BRIDGE_HUB_HEADER_SIZE
  Maximal bridge hub header size.
• MAX_UNCONFIRMED_MESSAGES_IN_CONFIRMATION_TX
  Maximal number of unconfirmed messages at inbound lane for Cumulus-based parachains. Note: this value is security-relevant, decreasing it should not be done without careful analysis (like the one above).
• MAX_UNREWARDED_RELAYERS_IN_CONFIRMATION_TX
  Maximal number of unrewarded relayer entries at inbound lane for Cumulus-based parachains. Note: this value is security-relevant, decreasing it should not be done without careful analysis (like the one above).
• NORMAL_DISPATCH_RATIO
  All cumulus bridge hubs allow normal extrinsics to fill block up to 75 percent.
• TX_EXTRA_BYTES
  Maximal number of bytes, included in the signed Polkadot-like transaction apart from the encoded call itself.

Type Aliases

• AccountId
  Id of account on Polkadot-like chains.
• AccountPublic
  Public key of account on Polkadot-like chains.
• AccountSigner
  Public key of the chain account that may be used to verify signatures.
• Address
  The address format for describing accounts.
• Balance
  The balance of an account on Polkadot-like chain.
• BlockNumber
  Block number type used in Polkadot-like chains.
• Hash
  Hash type used in Polkadot-like chains.
• Hasher
  The type of object that can produce hashes on Polkadot-like chains.

• Signature
  Signature type used by Polkadot-like chains.
• SignedBlock
  Polkadot-like block signed with a Justification.
• TransactionExtension
  Signed extension that is used by all bridge hubs.
• UncheckedExtrinsic
  Unchecked Extrinsic type.
