Trait representing a call that is a sub type of pallet_bridge_messages::Call.

Required Methods

fn receive_messages_proof_info( &self, ) -> Option<ReceiveMessagesProofInfo<T::LaneId>>

Create a new instance of ReceiveMessagesProofInfo from a ReceiveMessagesProof call.

fn receive_messages_delivery_proof_info( &self, ) -> Option<ReceiveMessagesDeliveryProofInfo<T::LaneId>>

Create a new instance of ReceiveMessagesDeliveryProofInfo from a ReceiveMessagesDeliveryProof call.

fn call_info(&self) -> Option<MessagesCallInfo<T::LaneId>>

Create a new instance of MessagesCallInfo from a ReceiveMessagesProof or a ReceiveMessagesDeliveryProof call.

fn call_info_for( &self, lane_id: T::LaneId, ) -> Option<MessagesCallInfo<T::LaneId>>

Create a new instance of MessagesCallInfo from a ReceiveMessagesProof or a ReceiveMessagesDeliveryProof call, if the call is for the provided lane.

fn check_obsolete_call(&self) -> TransactionValidity

Ensures that a ReceiveMessagesProof or a ReceiveMessagesDeliveryProof call:

• does not deliver already delivered messages. We require all messages in the ReceiveMessagesProof call to be undelivered;

• does not submit empty ReceiveMessagesProof call with zero messages, unless the lane needs to be unblocked by providing relayer rewards proof;

• brings no new delivery confirmations in a ReceiveMessagesDeliveryProof call. We require at least one new delivery confirmation in the unrewarded relayers set;

• does not violate some basic (easy verifiable) messages pallet rules obsolete (like submitting a call when a pallet is halted or delivering messages when a dispatcher is inactive).

If one of above rules is violated, the transaction is treated as invalid.
