Module substrate_relay_helper::cli::relay_headers_and_messages

Complex 2-ways headers+messages relays support.

To add new complex relay between ChainA and ChainB, you must:

1. ensure that there’s a declare_chain_cli_schema!(...) for both chains.
2. add declare_chain_to_chain_bridge_schema!(...) or declare_chain_to_parachain_bridge_schema for the bridge.
3. declare a new struct for the added bridge and implement the Full2WayBridge trait for it.

Modules

• parachain_to_parachain
  Parachain to parachain relayer CLI primitives.
• relay_to_parachain
  Relay chain to parachain relayer CLI primitives.
• relay_to_relay
  Relay chain to Relay chain relayer CLI primitives.

Structs

• BridgeEndCommonParams
  Parameters that are associated with one side of the bridge.
• Full2WayBridgeCommonParams
  Bridge parameters, shared by all bridge types.
• FullBridge
  All data of the bidirectional complex relay.
• HeadersAndMessagesSharedParams
  Parameters that have the same names across all bridges.

Traits

• Full2WayBridge
  Bidirectional complex relay.
• Full2WayBridgeBase
  Base portion of the bidirectional complex relay.
