Crate bp_bridge_hub_kusama 

Module with configuration which reflects BridgeHubKusama runtime setup (AccountId, Headers, Hashes…)

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.

BridgeHubKusama

BridgeHubKusama parachain.

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.

BEST_FINALIZED_BRIDGE_HUB_KUSAMA_HEADER_METHOD

Name of the <ThisChain>FinalityApi::best_finalized runtime method.

BRIDGE_HUB_KUSAMA_PARACHAIN_ID

Identifier of BridgeHubKusama in the Kusama relay chain.

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.

FREE_HEADERS_INTERVAL_FOR_BRIDGE_HUB_KUSAMA_METHOD

Name of the <ThisChain>FinalityApi::free_headers_interval runtime method.

FROM_BRIDGE_HUB_KUSAMA_MESSAGE_DETAILS_METHOD

Name of the From<ThisChain>InboundLaneApi::message_details runtime method.

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.

TO_BRIDGE_HUB_KUSAMA_MESSAGE_DETAILS_METHOD

Name of the To<ThisChain>OutboundLaneApi::message_details runtime method.

TX_EXTRA_BYTES

Maximal number of bytes, included in the signed Polkadot-like transaction apart from the encoded call itself.

WITH_BRIDGE_HUB_KUSAMA_MESSAGES_PALLET_NAME

Name of the With-BridgeHubKusama messages pallet instance that is deployed at bridged chains.

WITH_BRIDGE_HUB_KUSAMA_RELAYERS_PALLET_NAME

Name of the With-BridgeHubKusama bridge-relayers pallet instance that is deployed at bridged chains.

Traits

BridgeHubKusamaFinalityApi

API for querying information about the finalized chain headers.

FromBridgeHubKusamaInboundLaneApi

Inbound message lane API for messages sent by this chain.

ToBridgeHubKusamaOutboundLaneApi

Outbound message lane API for messages that are sent to this chain.
