Crate bp_messages

Primitives of messages module.

Modules

• source_chain
  Primitives of messages module, that are used on the source chain.
• storage_keys
  Storage keys of bridge messages pallet.
• target_chain
  Primitives of messages module, that are used on the target chain.

Structs

• BaseMessagesProofInfo
  Generic info about a messages delivery/confirmation proof.
• DeliveredMessages
  Delivered messages with their dispatch result.
• HashedLaneId
  Bridge lane identifier.
• InboundLaneData
  Inbound lane data.
• InboundMessageDetails
  Inbound message details, returned by runtime APIs.
• LegacyLaneId
  Bridge lane identifier (legacy).
• Message
  Message as it is stored in the storage.
• MessageKey
  Message key (unique message identifier) as it is stored in the storage.
• OutboundLaneData
  Outbound lane data.
• OutboundMessageDetails
  Outbound message details, returned by runtime APIs.
• ReceiveMessagesDeliveryProofInfo
  Info about a ReceiveMessagesDeliveryProof call which tries to update a single lane.
• ReceiveMessagesProofInfo
  Info about a ReceiveMessagesProof call which tries to update a single lane.
• ReceivedMessages
  Received messages with their dispatch result.
• UnrewardedRelayer
  Unrewarded relayer entry stored in the inbound lane data.
• UnrewardedRelayerOccupation
  Occupation state of the unrewarded relayers vector.
• UnrewardedRelayersState
  Gist of InboundLaneData::relayers field used by runtime APIs.
• Weight

Enums

• BridgeMessagesCall
  A minimized version of pallet-bridge-messages::Call that can be used without a runtime.
• LaneState
  Lane state.
• MessagesCallInfo
  Info about a ReceiveMessagesProof or a ReceiveMessagesDeliveryProof call which tries to update a single lane.
• MessagesOperatingMode
  Messages pallet operating mode.
• ReceptionResult
  Result of single message receival.
• VerificationError
  Error that happens during message verification.

Constants

• HARD_MESSAGE_SIZE_LIMIT
  Hard limit on message size that can be sent over the bridge.

Traits

• ChainWithMessages
  Substrate-based chain with messaging support.
• LaneIdType
  Trait representing a generic LaneId type.

Functions

• calc_relayers_rewards
  Calculate the number of messages that the relayers have delivered.
• maximal_incoming_message_size
  Return maximal size of the message the chain with max_extrinsic_size is able to receive.

Type Aliases

• MessageNonce
  Message nonce. Valid messages will never have 0 nonce.
• MessagePayload
  Opaque message payload. We only decode this payload when it is dispatched.
