Module messages

Tools for supporting message lanes between two Substrate-based chains.

Modules

• metrics
  Tools for supporting message lanes between two Substrate-based chains.
• source
  Substrate client as Substrate messages source. The chain we connect to should have runtime that implements <BridgedChainName>HeaderApi to allow bridging with <BridgedName> chain.
• target
  Substrate client as Substrate messages target. The chain we connect to should have runtime that implements <BridgedChainName>HeaderApi to allow bridging with <BridgedName> chain.

Structs

• BatchProofTransaction
  Batch transaction that brings headers + and messages delivery/receiving confirmations to the source node.
• DirectReceiveMessagesDeliveryProofCallBuilder
  Building receive_messages_delivery_proof call when you have direct access to the source chain runtime.
• DirectReceiveMessagesProofCallBuilder
  Building receive_messages_proof call when you have direct access to the target chain runtime.
• MessageLaneAdapter
  Adapter that allows all SubstrateMessageLane to act as MessageLane.
• MessagesRelayLimits
  Delivery transaction limits.
• MessagesRelayParams
  Substrate <-> Substrate messages relay parameters.

Traits

• ReceiveMessagesDeliveryProofCallBuilder
  Different ways of building receive_messages_delivery_proof calls.
• ReceiveMessagesProofCallBuilder
  Different ways of building receive_messages_proof calls.
• SubstrateMessageLane
  Substrate -> Substrate messages synchronization pipeline.

Functions

• relay_messages_delivery_confirmation
  Relay messages delivery confirmation of Substrate-to-Substrate messages. No checks are made to ensure that transaction will succeed.
• relay_messages_range
  Deliver range of Substrate-to-Substrate messages. No checks are made to ensure that transaction will succeed.
• run
  Run Substrate-to-Substrate messages sync loop.
