Crate bp_kusama

Primitives of the Kusama chain.

Modules

• parachains
  Primitives of polkadot-like chains, that are related to parachains functionality.
• time_units
  Human readable time units defined in terms of number of blocks.

Structs

• AccountInfoStorageMapKeyProvider
  Provides a storage key for account data.
• BlockLength
  All Polkadot-like chains have maximal block size set to 5MB.
• BlockWeights
  All Polkadot-like chains have the same block weights.
• ExtrinsicBaseWeight
  Time to execute a NO-OP extrinsic, for example System::remark. Calculated by multiplying the Average with 1.0 and adding 0.
• Kusama
  Kusama Chain
• Perbill
  A fixed point representation of a number in the range [0, 1].

Constants

• AVERAGE_HEADER_SIZE
  Average header size in votes_ancestries field of justification on Polkadot-like chains.
• AVERAGE_ON_INITIALIZE_RATIO
  All Polkadot-like chains assume that an on-initialize consumes 1 percent of the weight on average, hence a single extrinsic will not be allowed to consume more than AvailableBlockRatio - 1 percent.
• BEST_FINALIZED_KUSAMA_HEADER_METHOD
  Name of the <ThisChain>FinalityApi::best_finalized runtime method.
• DAYS
  A day, expressed in Polkadot-like chain blocks.
• 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.
• HOURS
  A hour, expressed in Polkadot-like chain blocks.
• KUSAMA_SYNCED_HEADERS_GRANDPA_INFO_METHOD
  Name of the <ThisChain>FinalityApi::accepted_<consensus>_finality_proofs runtime method.
• MAXIMUM_BLOCK_WEIGHT
  All Polkadot-like chains allow 2 seconds of compute with a 6-second average block time.
• MAX_AUTHORITIES_COUNT
  Maximal number of GRANDPA authorities at Polkadot-like chains.
• MAX_MANDATORY_HEADER_SIZE
  Approximate maximal header size on Polkadot-like chains.
• MAX_MESSAGES_IN_DELIVERY_TRANSACTION
  Maximal number of messages in single delivery transaction.
• MAX_NESTED_PARACHAIN_HEAD_DATA_SIZE
  Maximal size of encoded bp_parachains::ParaStoredHeaderData structure among all Polkadot parachains.
• MILLISECS_PER_BLOCK
  Milliseconds between Polkadot-like chain blocks.
• MINUTES
  A minute, expressed in Polkadot-like chain blocks.
• PARAS_PALLET_NAME
  Name of the parachains pallet in the Kusama runtime.
• REASONABLE_HEADERS_IN_JUSTIFICATION_ANCESTRY
  Reasonable number of headers in the votes_ancestries on Polkadot-like chains.
• SLOT_DURATION
  Slot duration in Polkadot-like chain consensus algorithms.
• TX_EXTRA_BYTES
  Maximal number of bytes, included in the signed Polkadot-like transaction apart from the encoded call itself.
• WITH_KUSAMA_GRANDPA_PALLET_NAME
  Name of the With-Kusama GRANDPA pallet instance that is deployed at bridged chains.

Traits

• Convert
  Infallible conversion trait. Generic over both source and destination types.
• KusamaFinalityApi
  API for querying information about the finalized chain headers.
• Parameter
  A type that can be used as a parameter in a dispatchable function.
• SuffixedCommonSignedExtensionExt
  Helper trait to define some extra methods on SuffixedCommonSignedExtension.

Functions

• max_extrinsic_size
  Returns maximal extrinsic size on all Polkadot-like chains.
• max_extrinsic_weight
  Returns maximal extrinsic weight on all Polkadot-like chains.

• Address
  Account address, used by the Polkadot-like chain.
• Balance
  The balance of an account on Polkadot-like chain.
• Block
  Block type of Polkadot-like chains.
• BlockNumber
  Block number type used in Polkadot-like chains.

• SignedBlock
  Polkadot-like block signed with a Justification.
• SignedExtension
  Signed extension that is used by most chains.
• SuffixedCommonSignedExtension
  Extra signed extension data that starts with CommonSignedExtra.
